Tips to beat insomnia

This article gives 10 tips to help you beat insomnia.

Insomnia is the inability to get enough sleep needed to wake up feeling refreshed and well-rested.  Millions of people are suffering from this sleeping disorder.   You can cure insomnia without the additional cost of medication with just little changes in your lifestyle.

1. What you drink and eat before bedtime are also factors that can induce insomnia.  Cut down on alcohol, and do not eat heavy meals before bedtime.  Stick to light snacks and chamomile tea.Cut the caffeine – caffeine is a stimulant.  Cut down on other drinks and foods that have caffeine also, like sodas, teas, and tiramisus.  Coffee should be drank in the morning or at least eight hours before sleep.
2. Keep a quite, dark, and cool bedroom – an uncomfortable sleeping area will not induce sleep. Noise, light, and heat interfere with sleep.
3. The bed is for sleeping and sex – train your brain and body that the bed is for sleeping and sex. Doing office work and reading in bed is a no-no.  The goal is to associate the bed with relaxation and sleep.  Avoid watching TV while lying down in bed, watching TV stimulates your brain to think.  It may make your eyes tired, but the brain is busy converting images to thoughts.  Better yet, transfer the TV to the living room.
4. Avoid naps – try hard not to get that super nap in the afternoon. Naps disrupts sleep at night.  If you really can’t avoid it, limit it to 30 minutes before 3 pm.
5. Quit Smoking – nicotine, like caffeine, is a stimulant. The more you smoke, the more awake you’ll be.  Aside from the hazards of smoking, quitting will do wonders on your sleeping habits.
6. Change the way you think about insomnia – self-defeating thoughts help fuel insomnia. Think positive.  Instead of thoughts like “It’s the same every night,  another night of misery’, think this way instead “This does not every nught, some nights I get enough rest.”  Don’t worry too much, quit this mental habit.
7. Do away with stressful situations before bedtime – avoid heated discussions, heavy mental activities, even strenious activities before bedtime. Try some relaxing activities instead, listening to soft music with keeping the lights low will help in relaxing the brain.
8. Ban Blue Light in the bedroom – Short waves from blue light interferes with sleep. Use devices that have blue light an hour before going to sleep.  This includes TV, cellphones, and digital clocks.
9. Fat or Flat – not the body types, this refers to pillows. The discomfort you give your necks affects the quality of sleep, aside from having a sore neck upon waking up.  Pillows should be just the right size.  Side sleepers should have their nose align with the center of the body while sleeping.  Stomach sleeping should be avoided as this cranes the neck.
10. Control your body clock – go to sleep and wake up around the same time daily, irregardless if its a holiday or a weekend the next day. Our bodies have biological clocks and it is light regulated.  Try getting a ray of sunshine the minute you wake up, for 5 to 30 minutes.

Kids with ADHD may be more likely to drink and smoke

A study shows that kids who have ADHD may be more likely to drink and smoke as teenagers.

Teens are more likely to start smoking or drinking with each additional symptom they have of attention-deficit hyperactivity disorder (ADHD) or conduct disorder, new research suggests.

"Our findings underscore the need to counsel families about the risk of substance use as [these] children approach adolescence," said study author Dr. William Brinkman, research director at Cincinnati Pediatric Research Group, which is part of Cincinnati Children's Hospital. "This need is heightened among children with ADHD and/or conduct disorder diagnoses or symptoms."

Brinkman's team analyzed data on more than 2,500 teens, aged 12 to 15, in a national survey conducted with their parents between 2000 and 2004.

First, the researchers identified the teens with an ADHD and/or conduct disorder diagnosis, as well as those with the symptoms of either disorder, regardless of whether there was a diagnosis. Conduct disorder is characterized by aggressive, destructive or deceitful behavior. Children with ADHD tend to be hyperactive, impulsive and/or inattentive.

Then Brinkman's team compared use of tobacco and alcohol among the teens, to look for a link between symptoms of ADHD or conduct disorder and substance use.

Brinkman said that 45 percent of the children in the study had at least one ADHD symptom, and nearly 15 percent had at least one conduct disorder symptom.

For each additional ADHD symptom related to inattention -- but not hyperactivity or impulsivity -- the risk that a teen would use tobacco or alcohol increased by 8 percent to 10 percent. Similarly, each additional conduct disorder symptom was linked to a 31 percent increase in the likelihood of using tobacco, according to the study.

A very small percentage of teens in the study -- about 1.5 percent -- were diagnosed with both ADHD and conduct disorder. These teens were more than three times more likely to use tobacco or alcohol, even after accounting for differences in age, race/ethnicity, sex, household income and having a household member who smoked.

The findings were published recently in the journal Drug and Alcohol Dependence.

Brinkman said more research may provide clues as to why the link exists between these disorders and substance use.

"Because nicotine can improve attention and arousal, some have speculated that the association between inattention symptoms and higher rates of tobacco use suggests a form of self-medication for ADHD," Brinkman said. "Certainly higher rates of risk taking and novelty seeking has been documented among children with a diagnosis of ADHD, as well as those with ADHD symptoms [but too few for a diagnosis]."

Social pressures may be involved as well, suggested Dr. Glen Elliott, chief psychiatrist and medical director of Children's Health Council in Palo Alto, Calif.

"It is important to emphasize that not all teens with ADHD follow this path, just a higher percentage than those without ADHD," Elliott said. "We believe it is a combination of impulsive decision-making and perhaps the social strain that ADHD can place on the individual, who may feel unable to connect with peers in socially acceptable ways and therefore more vulnerable to trying other methods such as doing things peers dare them to do or that they view as 'cool' or 'adult.' "

Elliott said the study provides new insights into the interplay between ADHD and conduct disorder. But it sheds little light on whether treating ADHD, either earlier in childhood or during adolescence, might change the risk of starting to smoke or drink, he said.

"We believe medication can make a difference, but the evidence is not nearly as compelling as we wish it were -- partly because teens often go through a phase of refusing to take medications just when it might do them the most good," Elliott said. "Just as with parents of any teenager, there is no guaranteed way to prevent a son or daughter from experimenting if they are determined to do so."

The best tools parents have, Elliott said, are setting consistent and clear expectations for their children, closely monitoring them, praising them for good choices and administering appropriate, meaningful consequences for poor choices -- while also showing children early on what behavior is acceptable.

"Adolescence is hard," Elliott said. "And having ADHD can make it harder. So parents need to be vigilant, caring, consistent and involved."

Study: Smokers can learn to dislike cigarettes while sleeping

A study claims that smokers can be taught to dislike cigarettes while they are sleeping.

Bad smells during sleep may teach smokers to dislike cigarettes and help them cut back, a new study hints.

Smokers who were exposed to the smell of cigarettes along with an unpleasant odor during a single night of sleep smoked less for days afterward, the researchers found.

This study shows that "sleep learning can influence later wake behavior," says Anat Arzi. She's a PhD student at the Weizmann Institute of Science in Rehovot, Israel.

She presented the study at the Society for Neuroscience 2014 Annual Meeting in Washington, D.C.

Subliminal Messages

"This research stems from recent findings suggesting that novel associations can be learned during human sleep and retrieved upon awakening," Arzi said during a media briefing.

The researchers chose this method because the brain’s reward system, which is activated during addictive behavior, shares traits with the olfactory system, or sense of smell.

The study involved 76 adult smokers who wanted to quit. During 1 night in the sleep lab, they were exposed to cigarette smells and the smell of rotten fish or rotten eggs during light sleep (known as stage 2 sleep) or during "rapid eye movement" (REM) sleep, when people tend to dream. The odors didn't wake up the participants, Arzi said.

The experiment was also done while the smokers were awake. 

They kept a diary of how many cigarettes they smoked for 7 days before and 7 days after the experiment.

The linking of the cigarette smell to the rotten food smell is called aversive conditioning. The smokers who had aversive conditioning during stage 2 sleep reduced smoking by 34% in the following week. When conditioning was done during REM sleep, they cut back on smoking by 12%.

"The reduction in smoking was significantly larger and longer-lasting following conditioning during stage 2 sleep in comparison to REM sleep," Arzi said.

Aversive conditioning while smokers were awake did not lessensmoking.

"We know that behavioral approaches can help treat nicotine addiction, but none have been remarkably successful," Arzi said in a conference statement.

More study is needed to figure out whether the tactic could work as a quit-smoking aid and a potential treatment for addiction in general, she said during the briefing.

Useful Tool

Marina Picciotto, PhD, from Yale University, said the findings "could be a very useful tool to both motivate and assist people in quitting who might not otherwise have even thought about quitting. This study used smokers, but you could imagine that this could be applied to any addiction."

"We don't know yet from this early study how long the effect lasts and how useful it will be to actually induce quitting, but … the potential as a treatment is there," Picciotto said.

No link between sleep apnea and cancer

A study shows there is no link between sleep apnea and cancer.

Canadian researchers have found no apparent connection between sleep apnea and cancer in a new study of more than 10,000 people with this common sleep disorder.

People with sleep apnea experience repeated periods of disrupted breathing during sleep. Studies suggesting a link between the condition and cancer risk theorized that low oxygen levels might trigger cell mutations connected with cancer.

"We were not able to confirm previous hypotheses that obstructive sleep apnea is a cause of overall cancer development through intermittent lack of oxygen," said lead author Dr. Tetyana Kendzerska, from the Institute for Clinical Evaluative Sciences and Women's College Hospital at the University of Toronto.

The report, published Aug. 5 in the Canadian Medical Association Journal, is unlikely to put the question to rest, however.

"Additional studies are needed to find out whether there is an independent effect of sleep apnea on specific types of cancer," Kendzerska said.

Dr. Leonard Lichtenfeld, deputy chief medical officer of the American Cancer Society, said the findings suggest that sleep apnea by itself is not related to an increased risk of cancer. "However, for some people the factors that cause sleep apnea are related to an increased risk of cancer," he said.

Risk factors for sleep apnea include smoking, chronic lung disease, obesity and diabetes, Lichtenfeld said. "It is these conditions that are more likely to cause the increased cancer risk seen in other studies, not the sleep apnea itself," he said.

This study isn't the "final answer," he said. "More research will have to be done."

For the study, Kendzerska and colleagues studied about 10,150 patients suffering from sleep apnea who took part in a sleep study between 1994 and 2010. They linked this data to health databases from 1991 to 2013.

At the start of the study, about 5 percent of the patients had cancer. Over an average of nearly eight years of follow-up, an additional 6.5 percent of the participants developed cancer. Most common were prostate, breast, colorectal and lung cancers, the researchers said.

Although no link was seen for cancer in general, the researchers did find that low oxygen levels related to sleep apnea were associated with smoking-related cancers, such as lung cancer.

Dr. Yosef Krespi, director of the Center for Sleep Disorders at Lenox Hill Hospital in New York City, cautioned that while sleep apnea may not cause cancer, it is a serious condition that needs to be treated.

"One should not ignore sleep apnea," Krespi said. "Sleep apnea is a chronic progressive disorder that if left untreated can result in serious heart problems."

More than 18 million American adults have sleep apnea, according to the National Sleep Foundation. Some experts say the condition is increasing because of the obesity epidemic.

Sleep apnea can make a cancer patient's life more difficult, Krespi said.

"The quality of life of sleep apnea patients with cancer and their ability to tolerate treatments such as chemotherapy and radiation can be very different than those without the condition," he said.

Treating ADHD lowers the chance that a child will smoke

A study shows that treating ADHD lowers the chances that children with ADHD will smoke.

Children taking medications to treat attention-deficit/hyperactivity disorder (ADHD) -- such as Adderall, Ritalin and Vyvanse -- are less likely to smoke, according to a new analysis.

Kids with ADHD who were treated with these so-called stimulant medications were about half as likely to smoke as children with this disorder who weren't treated with these medications, researchers found.

"We found an association between getting treated with stimulant medications and having a lower risk of smoking in adolescence and adulthood," said study researcher Erin Schoenfelder, clinical psychologist at Duke University School of Medicine in Durham, N.C.

The study, which was funded by the U.S. National Institute on Drug Abuse, is published online May 12 and in the June print issue of the journalPediatrics.

About 11 percent of American children aged 4 to 17 have a diagnosis of ADHD, according to the U.S. Centers for Disease Control and Prevention (CDC). Children with ADHD can be impulsive, have trouble concentrating and may have other behavior problems. About 70 percent to 80 percent of children respond to stimulant medicine, according to the CDC. Behavior therapy can also help.

Experts have long known that children with ADHD have a higher risk of starting to smoke cigarettes. Teens with ADHD are two to three times more likely to smoke cigarettes than their friends who don't have the diagnosis, according to Schoenfelder, citing previous research.

But, research on the effects of ADHD stimulant medicine on the risk of smoking has been conflicting.

To try to better answer the question of whether or not these medications could help prevent kids from smoking, the Duke researchers re-analyzed the results of 14 studies of cigarette smoking and ADHD treatments. The studies included more than 2,300 children with ADHD. About 1,400 of the kids were being treated with stimulant medications, according to the new analysis.

The studies were published between 1980 and 2013. The average follow-up time was about seven years. The researchers compared the teens treated with stimulants to those who weren't to see which group was more likely to smoke.

Overall, those on medications were about half as likely to smoke as those not on the medications, Schoenfelder said.

"Those who took their medication consistently and for a longer period of time had an even lower risk of smoking," she added.

The data she analyzed overwhelmingly showed that medications appear to decrease the risk of smoking, according to Schoenfelder.

Like all medications, ADHD medicines have side effects. This analysis showed a "slight effect" on growth, she said. However, that finding must be weighed against the many positive long-term benefits, she explained.

Schoenfelder pointed out that the researchers "can't say based on this study that the treatment caused the lower rate of smoking, but there is an association we found."

However, association does not prove a cause-and-effect relationship.

One potential reason medication might have an effect is that both nicotine and the stimulant medications used to treat ADHD operate on the same pathways in the brain. They both improve the same processes that are disrupted in ADHD, according to Schoenfelder.

"Kids who have ADHD know that something is not quite right," said Dr. Trevor Resnick, chief of the department of neurology at Miami Children's Hospital, who commented on the study.

"They try to self-medicate," he explained, and "cigarettes would be an example of self-medication." As a result, children with ADHD have a much higher risk in general of turning to cigarettes, pot or illicit drugs, he said.

"What this study shows, similar to previous research, is that successful treatment of ADHD with stimulant medication decreases the risk of self-medication in these children," Resnick noted.

While stimulant medications do have several possible side effects, Resnick said, "most kids are able to tolerate" the medication.

Smoking rates lower with ADHD treatment

A study found that treating ADHD is associated with a lower rate of smoking.

Treating attention deficit hyperactivity disorder (ADHD) with stimulant medication may reduce smoking risk, especially when medication is taken consistently, according to an analysis led by researchers at Duke Medicine.

The findings appear online May 12, 2014, in the journal Pediatrics.

"Given that individuals with ADHD are more likely to smoke, our study supports the use of stimulant treatment to reduce the likelihood of smoking in youth with ADHD," said senior author Scott Kollins, Ph.D., professor of psychiatry and behavioral sciences and director of the Duke ADHD Program. "The risk is further lowered when adherence to medication treatment is consistent, presumably since this increases the chances that symptoms are managed effectively."

ADHD is a common childhood disorder that can continue through adolescence and adulthood, and is characterized by hyperactivity, difficulty paying attention and impulsivity. It is most commonly treated with stimulant medication (such as Vyvanse or Concerta), as well as with behavior therapy or a combination of the two.

Individuals with ADHD smoke at rates significantly higher than the general population, and they often start earlier. Studies have shown that youth with ADHD are two to three times more likely to smoke cigarettes than their peers, and 40 percent of adults with ADHD smoke regularly, more than twice the rate among adults without ADHD.

Research on how stimulant medications influence smoking behaviors in individuals with ADHD has led to mixed results. Some studies suggest an increase in smoking among those treated with stimulant medications, while others showed no effect or a decrease in smoking.

"Nicotine operates on the same pathways in the brain as stimulant medications, and the relationship between stimulants and smoking has been controversial," said lead author Erin Schoenfelder, Ph.D., clinical associate and a psychologist in the Duke ADHD Program.

"It has been suggested that some people with ADHD 'self-medicate' their attention deficits using nicotine," Schoenfelder said. "Our findings show that treating ADHD effectively with medication may prevent young people from picking up the habit."

The researchers examined 14 longitudinal studies of cigarette smoking and ADHD treatment, including a total of 2,360 individuals with ADHD, making this the largest meta-analysis on the issue to date.

Some of the studies used nicotine dependence to measure smoking behaviors, although nicotine dependence may not be found in adolescents who recently started smoking. In order to capture an accurate picture of smoking behaviors, the researchers expanded their criteria beyond nicotine dependence to include smoking frequency and whether participants currently smoked.

The analysis revealed a significant association between stimulant treatment and lower smoking rates. The effect was larger in those with more severe ADHD and when participants took stimulant medications continuously.

The researchers noted that based on the design of the study, they were able to identify an association but not a causal relationship between reduced smoking risk and stimulant treatment. Additional studies are needed to determine the recommended timing and duration of stimulant treatment to help lower smoking risk.

"This study may debunk the perception that stimulants will increase one's risk for smoking," Kollins said. "It gives us more confidence when we talk with parents to reassure them that consistent ADHD treatment won't increase their children's risk of smoking, and in fact, may actually do the opposite."

"My hope is that this research can help inform our efforts to prevent negative outcomes for kids with ADHD, including cigarette smoking," Schoenfelder said. "This population hasn't been targeted for smoking prevention efforts, despite the well-known connection between ADHD and smoking."

Quitting smoking can help you with a good night's sleep

A recent study shows that quitting smoking has many health benefits, such as increasing her sleep quality.

As if cancer, heart disease and other diseases were not enough motivation to make quitting smoking your New Year's resolution, here's another wake-up call: New research published in the January 2014 issue of The FASEB Journal suggests that smoking disrupts the circadian clock function in both the lungs and the brain. Translation: Smoking ruins productive sleep, leading to cognitive dysfunction, mood disorders, depression and anxiety.

"This study has found a common pathway whereby cigarette smoke impacts both pulmonary and neurophysiological function. Further, the results suggest the possible therapeutic value of targeting this pathway with compounds that could improve both lung and brain functions in smokers," said Irfan Rahman, Ph.D., a researcher involved in the work from the Department of Environmental Medicine at the University of Rochester Medical Center in Rochester, N.Y. "We envisage that our findings will be the basis for future developments in the treatment of those patients who are suffering with tobacco smoke-mediated injuries and diseases.

Rahman and colleagues found that tobacco smoke affects clock gene expression rhythms in the lung by producing parallel inflammation and depressed levels of brain locomotor activity. Short- and long- term smoking decreased a molecule known as SIRTUIN1 (SIRT1, an anti-aging molecule) and this reduction altered the level of the clock protein (BMAL1) in both lung and brain tissues in mice. A similar reduction was seen in lung tissue from human smokers and patients with chronic obstructive pulmonary disease (COPD). They made this discovery using two groups of mice which were placed in smoking chambers for short-term and long-term tobacco inhalation. One of the groups was exposed to clean air only and the other was exposed to different numbers of cigarettes during the day. Researchers monitored their daily activity patterns and found that these mice were considerably less active following smoke exposure.

Scientists then used mice deficient in SIRT1 and found that tobacco smoke caused a dramatic decline in activity but this effect was attenuated in mice that over expressed this protein or were treated with a small pharmacological activator of the anti-aging protein. Further results suggest that the clock protein, BMAL1, was regulated by SIRT1, and the decrease in SIRT1 damaged BMAL1, resulting in a disturbance in the sleep cycle/molecular clock in mice and human smokers. However, this defect was restored by a small molecule activator of SIRT1.

"If you only stick to one New Year's resolution this year, make it quitting smoking," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "Only Santa Claus has a list longer than that of the ailments caused or worsened by smoking. If you like having a good night's sleep, then that's just another reason to never smoke."

Sleep apnea risk factors

This article discusses different risk factors for obstructive sleep apnea.

Obstructive sleep apnea is a deadly sleep disorder. Those with obstructive sleep apnea may feel lethargic after a good night's sleep or you may snore loudly. But, there are certain risk factors associated with obstructive sleep apnea. We explore these risk factors.

Risk factors of obstructive sleep apnea:

1) Age: Obstructive sleep apnea is mainly associated with age. Those above 60 are prone to obstructive sleep apnea, but there are other risk factors that bring down the age group for sleep apnea.

2) Males: Having the X and Y chromosomes can make you prone to obstructive sleep apnea.Yes, males have a higher chance of developing apnea.

3) Weight: Excessive weight can result in obstructive sleep apnea. Over weight individuals tend to have thicker necks which make it difficult to breath. But obstructive sleep disorder can also affect individuals who are thin.

4) Genes: Family history of obstructive sleep disorder and narrow airway that you may have inherited are risk factors for obstructive sleep apnea.

5) Menopause: Though obstructive sleep apnea is prone to men, it can affect women after their menopause, especially is they are overweight.

6) Difficulty is breathing: Individuals who have nasal congestion and allergies associated with the respiration system are likely to develop obstructive sleep apnea. But it also depends on the breathing with correlation to the above mentioned risk factors.

7) Smoking: Smoking tends to build up water in the upper airway and also results in inflammation of the air way. These are the risk factors of developing obstructive sleep apnea.

8) Relaxed muscles: Sedatives that relaxes the muscles is a risk factor for obstructive sleep apnea.

Smoking during pregnancy may result in bipolar disorder in child

This study claims that a mother who smokes while pregnant has two times the risk of her child developing bipolar disorder compared to a mother who does not smoke while pregnant.

A study published today in theAmerican Journal of Psychiatry suggests an association between smoking during pregnancy and increased risk for developing bipolar disorder (BD) in adult children. Researchers at the New York State Psychiatric Institute and the Department of Epidemiology at the Mailman School of Public Health at Columbia University, in collaboration with scientists at the Kaiser Permanente Division of Research in Oakland, California, evaluated offspring from a large cohort of pregnant women who participated in the Child Health and Development Study (CHDS) from 1959-1966. The study was based on 79 cases and 654 comparison subjects. Maternal smoking during pregnancy was associated with a twofold increased risk of BD in their offspring.

Smoking during pregnancy is known to contribute to significant problems in utero and following birth, including low birth weight and attentional difficulties. This is the first study to suggest an association between prenatal tobacco exposure and BD, a serious psychiatric illness marked by significant shifts in mood that alternate between periods of depression and mania. Symptoms typically become noticeable in the late teens or early adulthood.

"These findings underscore the value of ongoing public health education on the potentially debilitating, and largely preventable, consequences that smoking may have on children over time," said Alan Brown, MD, MPH, senior author and Professor of Clinical Psychiatry and Epidemiology at the New York State Psychiatric Institute, Columbia University and Mailman School of Public Health.

The authors wrote: "Much of the psychopathology associated with prenatal tobacco exposure clusters around the 'externalizing' spectrum, which includes attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), conduct disorder (CD), and substance abuse disorders. Although not diagnostically classified along the externalizing spectrum, BD shares a number of clinical characteristics with these disorders, including inattention, irritability, loss of self-control, and proclivity to drug/alcohol use." In effect, children who were exposed to tobacco smoke in utero may exhibit some symptoms and behaviors that are found in BD.

A previous study by Dr. Brown and colleagues found that flu virus in pregnant mothers was associated with a fourfold increased risk that their child would develop BD.

What increases risk for sleep apnea?

This article discusses 8 things and behaviors that can increase a person's risk for sleep apnea.

It used to be that if someone told you you snored, you shrugged it off as more of an annoyance to them than anything telling about your own health and wellbeing.

Today, we have a greater understanding of at least one potential risk of being a frequent snorer: You could have sleep apnea, a potentially harmful sleep disorder during which people stop breathing, sometimes hundreds of times a night.

Obstructive sleep apnea (OSA) is the most common type of sleep apnea, and occurs when the muscles in the back of the throat collapse, causing the opening through which air passes to disappear. (Watch this video for an in-depth explanation of what happens during OSA.)

But certain people are more likely to experience this interruption of breathing than others. We asked Dr. Matthew Mingrone, lead physician for EOS Sleep Centers in California specializing in sleep apnea and snoring issues, to help explain why.

Obesity
Likely the most indicative risk factor is carrying too much extra weight. Obese adults are seven times more likely to develop OSA than their normal-weight peers, according to WebMD. OSA is essentially a blockage of the upper airway, says Mingrone. Part of the tissue running from the nose to the voicebox collapses, cutting off the passage of oxygen. Excess weight adds to the pressure on tube, he says, making the diameter of the opening even smaller than it already is.

Neck Circumference

Obese people aren't the only demographic with larger-than-average necks. Consider the muscular build of professional athletes, for example, who aren't obese but thanks to muscle development are larger than us mere mortals.

Men with a neck circumference greater than 17 inches and women over 15 inches have a higher risk of OSA, WebMD reported.

Age
People of any age can develop sleep apnea, but the condition is more common the older you get, according to the National Heart Lung and Blood Institute. "As we get older, we lose tone and elasticity as part of the normal aging process," says Mingrone. With that natural softening of the tissue in the throat, there's higher likelihood of collapse, he says.

Family History
It's not that you have a genetic predisposition to developing sleep apnea, says Mingrone, like a specific type of cancer that may run in families. Instead, it's likely that you've inherited certain aspects of your physical makeup that increase sleep apnea risk, he says. If Mom's being treated for sleep apnea and you've inherited her narrow jaw, you may have a similar doctor's visit in your future.

Alcohol Use

Because it's a muscle relaxant, alcohol too close to bedtime can lead to episodes of apnea, says Mingrone, even in someone who doesn't have OSA. And in those with the disorder, alcohol can lengthen the duration of apnea episodes, according to the National Institute on Alcohol Abuse and Alcoholism.

Race
Studies show that both sleep apnea risk and sleep apnea severity vary by race. It may be due to anatomical differences in the airways of different ethnic groups, according to Mingrone.

Smoking

Current smokers are 2.5 times more likely to have OSA than smokers and nonsmokers combined, according to a 2001 study. "Smoking most airway tissue swell because it's an irritant," says Mingrone. Swelling in the nose and the throat further reduces the space for air to flow through.

Gender
Middle-aged men are twice as likely to have OSA than women of the same age, according to the American Lung Association. Mingrone says in his practice, about 15 to 20 percent of patients are female. The variance may be due again to anatomical differences, especially since men are simply bigger than women more often than not.

Smoking leads to sleeping issues

Research suggest that smoking can negatively influence sleep and result in sleeping issues and disturbances.

Smoking may interfere with a good night's sleep, a new study suggests.

Despite being well established as the leading cause of preventable death and a wide range of health problems, smoking's effects on sleep are little understood.

In an effort to fill this gap in knowledge, researchers from the University of Florida and Research Triangle Park examined the relationship between sleep difficulty and smoking status among a nationally representative sample.

Twelve percent of current smokers, they found, reported trouble falling asleep, while 10 percent complained of waking too early. An additional 11 percent, moreover, said they often woke during the night.

Insufficient sleep is associated with a wide range of health problems, including depression, diabetes and high blood sugar. As a result, the researchers hypothesize that smokers may be putting themselves at risk for much more than the commonly recognized health problems associated with smoking, such as cancer and cardiovascular disease.

In an effort to decrease smoking rates across the United States, government health officials launched an anti-smoking campaign last year using funding provided by the Affordable Care Act's Prevention and Public Health Fund. Called "Tips From Former Smokers," the campaign was designed to depict in graphic detail the effects of smoking.

According to a study released by the Centers for Disease Control (CDC), the campaign prompted more than 1.6 million Americans to try to quit, of which 200,000 succeeded. 

All told, the results far exceeded the campaign's original goals of 500,000 quit attempts and 50,000 successful quits.

"This is exciting news," CDC Director Dr. Tom Frieden said in a statement. "Quitting can be hard, and I congratulate and celebrate with former smokers -- this is the most important step you can take to a longer, healthier life."

According to the CDC, more than 1,200 people living in the United States die every day due to the effects of smoking.

Study: Smoking during pregnancy may cause conduct issues in children

New research shows that smoking while pregnant is a risk factor for conduct problems, such as ADD, in offspring.

Research led by University of Leicester examines relationship between maternal smoking during pregnancy and offspring conduct problems among children.

Smoking during pregnancy appears to be a prenatal risk factor associated with conduct problems in children, according to a study published byJAMA Psychiatry, a JAMA Network publication.

Conduct disorder represents an issue of significant social, clinical, and practice concern, with evidence highlighting increasing rates of child conduct problems internationally. Maternal smoking during pregnancy is known to be a risk factor for offspring psychological problems, including attention deficits and conduct problems, the authors write in the study background.

Professor Gordon Harold and Dr. Darya Gaysina, of the University of Leicester, with colleagues in the United States and New Zealand, examined the relationship between maternal smoking during pregnancy and offspring conduct problems among children raised by genetically related mothers and genetically unrelated mothers.

Three studies were used: The Christchurch Health and Development Study (a longitudinal cohort study that includes biological and adopted children), the Early Growth and Development Study (a longitudinal adoption-at-birth study), and the Cardiff IVF (In Vitro Fertilization) Study (an adoption-at-conception study among genetically related families and genetically unrelated families). Maternal smoking during pregnancy was measured as the average number of cigarettes per day smoked during pregnancy.

According to the study results,a significant association between maternal smoking during pregnancy and offspring conduct problems was observed among children raised by genetically related mothers and genetically unrelated mothers. Results from a meta-analysis affirmed this pattern of findings across pooled study samples.

"Our findings suggest an association between pregnancy smoking and child conduct problems that is unlikely to be fully explained by postnatal environmental factors (i.e., parenting practices) even when the postnatal passive genotype-environment correlation has been removed." The authors conclude, "The causal explanation for the association between smoking in pregnancy and offspring conduct problems is not known but may include genetic factors and other prenatal environmental hazards, including smoking itself."

Health link between the heart and the brain

This article discusses the link between risk factors of heart disease and declining brain function.

Heart disease risk factors can lead to a decline in brain function in both younger and older adults, Dutch researchers report.

The new study included nearly 3,800 people, aged 35 to 82, who were checked for heart disease risk factors such as smoking, diabetes and high levels of "bad" cholesterol, and given tests to assess their memory and mental skills such as the ability to plan and reason and to begin and switch tasks.

Those with the highest risk for heart disease did 50 percent worse on the mental tests than those with the lowest risk. Two heart disease risk factors -- smoking and diabetes -- were especially associated with poorer brain function, according to the study in the May 2 issue of the journal Stroke.

The link between heart disease risk factors and reduced brain function was seen in all age groups, the investigators noted.

"Young adults may think the consequences of smoking or being overweight are years down the road, but they aren't," study author Dr. Hanneke Joosten, a nephrology fellow at the University Medical Center in Groningen, the Netherlands, said in a journal news release.

"Most people know the negative effects of heart risk factors such as heart attack, stroke and [kidney] impairment, but they do not realize it affects cognitive [mental] health. What's bad for the heart is also bad for the brain," Joosten added.

She said doctors need to be aware of this link between heart disease risk factors and brain function decline, and more public action is needed to reduce heart disease risk factors.

"Smoking cessation programs might not only prevent cancer, stroke and cardiovascular events, but also cognitive [mental] damage," Joosten said.

The association between heart risk factors and poorer brain function seen in the study does not prove a cause-and-effect relationship.

Gestational Diabetes and Poverty Linked to Increased Chance of ADHD

While gestational diabetes and poverty are shown to have an increased chance of a child having ADHD, breastfeeding shows the opposite effect.

Gestational diabetes and a lower socioeconomic status are the latest environmental factors to be associated with an increased risk of attention-deficit/hyperactivity disorder (ADHD), according to new research.

The German study found that children born to mothers who developed high blood sugar during pregnancy (gestational diabetes) were almost twice as likely to have ADHD as children born to mothers without gestational diabetes. The study also found more than double the risk of ADHD for children born into a family with a low socioeconomic status compared to those in the highest socioeconomic class. Children in the middle class had almost a 60 percent higher rate of ADHD compared to the upper-class children.

"This study found interesting associations that have public health implications," said Dr. Andrew Adesman, chief of developmental and behavioral pediatrics at the Steven and Alexandra Cohen Children's Medical Center of New York, in New Hyde Park, N.Y. Adesman wasn't involved in the current research.

"The U.S. is experiencing an increasing epidemic of obesity, which is a risk factor for gestational diabetes. We need to be mindful of the broader implications of these unfortunate trends. They won't just have an impact on the mother's health, but can also affect the offspring," Adesman said.

The good news from this study is they found that breast-feeding appeared to be protective. Children who were breast-fed were almost 20 percent less likely to develop ADHD, according to the study.

Results of the study were published online as a research letter in the Sept. 10 issue of the Archives of Pediatrics & Adolescent Medicine.

In the United States, more than 5 million children between 3 and 17 years of age have been diagnosed with ADHD, a neurobiological condition that often persists into adulthood. ADHD is characterized by difficulty focusing on tasks and controlling behavior, unusual restlessness and impulsiveness.

The authors of the new study noted they had seen a U.S. study suggesting that gestational diabetes and socioeconomic status might be linked to ADHD. So, they reviewed health information from a national German database and focused on more than 13,000 children and teens from 3 years to 17 years old.

Of that group, nearly 5 percent had an ADHD diagnosis.

In addition to the gestational diabetes and socioeconomic status findings, the researchers found a number of factors associated with the development of ADHD. Boys were more than four times as likely to develop the condition as girls were, according to the study.

Maternal smoking was associated with a nearly 50 percent increased risk of ADHD in the child. Perinatal health problems (such as birth defects, preterm birth and low birthweight) increased the risk of a child developing ADHD by 69 percent, according to the study. Researchers also found that having the allergic skin condition eczema was associated with a 62 percent increased risk of ADHD.

"During pregnancy and for the first few years after birth, the brain is undergoing active development, and is vulnerable to a range of influences," Adesman said.

Dr. Mary Rosser, an assistant professor of obstetrics, gynecology and women's health at Montefiore Medical Center, in New York City, said the study covers new ground.

"We've known for a while that perinatal factors have been cited as potential causes for many childhood problems," Rosser said. "Smoking during pregnancy has always been one of the factors that has been linked to ADHD in kids. This study is one of the first I've seen that's looking at gestational diabetes and ADHD."

Noting that "an unfavorable uterine environment can cause developmental issues," Rosser recommended that women see an obstetrician before getting pregnant, and that they continue prenatal care throughout their pregnancies. This can help prevent or treat some of the issues, such as gestational diabetes, that may contribute to ADHD in the child.

In addition, she recommended that women breast-feed their babies. Breast-feeding may be protective for ADHD, and it's known to be beneficial for the baby's overall health, she said.

The study did not prove that gestational diabetes and a lower socioeconomic status cause ADHD, it merely found an association.

Genes can Predict the Brain's Reaction to Smoking and other Addictions

A new study shows that genetics may play a role in how well people respond to smoking and other addicting behaviors.

Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. A study from the Montreal Neurological Institute and Hospital -- The Neuro, McGill University shows that people with genetically fast nicotine metabolism have a significantly greater brain response to smoking cues than those with slow nicotine metabolism.

Previous research shows that greater reactivity to smoking cues predicts decreased success at smoking cessation and that environmental cues promote increased nicotine intake in animals and humans. This new finding that nicotine metabolism rates affect the brain's response to smoking may lead the way for tailoring smoking cessation programs based on individual genetics.

Smoking cues, such as the sight of cigarettes or smokers, affect smoking behavior and are linked to relapse and cigarette use. Nicotine metabolism, by a liver enzyme, also influences smoking behavior. Variations in the gene that codes for this enzyme determine slow or fast rates of metabolism and therefore, the level of nicotine in the blood that reaches the brain. In the study smokers were screened for their nicotine metabolism rates and their enzyme genotype. Participants were aged 18 -- 35 and smoked 5-25 cigarettes daily for a minimum of 2 years. People with the slowest and fastest metabolism had their brain response to visual smoking cues measured using functional MRI. Fast metabolizers had significantly greater response to visual cigarette cues than slow metabolizers in brain areas linked to memory, motivation and reward, namely the amygdala, hippocampus, striatum, insula, and cingulate cortex.

"The finding that nicotine metabolism rate has an impact on the brain's response to smoking cues supports our hypothesis that individuals with fast nicotine metabolism rates would have a greater brain response to smoking cues because of close coupling in everyday life between exposure to cigarettes and surges in blood nicotine concentration. In other words they learn to associate cigarette smoking with the nicotine surge," says clinician-scientist Dr. Alain Dagher, lead investigator at The Neuro. "In contrast, individuals with slow metabolism rates, who have relatively constant nicotine blood levels throughout the day, are less likely to develop conditioned responses to cues. For them, smoking is not associated with brief nicotine surges, so they are smoking for other reasons. Possibilities include maintenance of constant brain nicotine levels for cognitive enhancement (ie, improved attention, memory), or relief of stress or anxiety."

Future research could focus on improving smoking cessation methods by tailoring treatments for different types of smokers. One possibility is to measure the rate of nicotine metabolism as part of the therapeutic decision-making process. For example, targeting cue-induced relapse risk may not help those with slow nicotine metabolism, who are more likely to benefit from long-acting cholinergic drugs such as the nicotine patch, consistent with previous clinical trials. Conversely the use of non-nicotine based therapies aimed at reducing craving may help fast metabolizers, as demonstrated for buproprion, an anti-depressant that has been used for smoking cessation.

Study: Smokers may have more sleep problems

A new study claims why smokers might sleep less and thus have more sleep problems.

Smokers may get fewer hours of sleep and have less restful slumber than non-smokers, according to a German study that looked at more than two thousand people.

Researchers whose work appeared in the journal Addiction Biology found that of nearly 1,100 smokers surveyed, 17 percent got fewer than six hours of sleep each night and 28 percent reported "disturbed" sleep quality.

That compared with rates of seven percent and 19 percent respectively among more than 1,200 non-smokers who were also surveyed, said lead researcher Stefan Cohrs, of Charite Berlin medical school in Germany.

"This study demonstrates for the first time an elevated prevalence of sleep disturbance in smokers compared with non-smokers in a population without lifetime history of psychiatric disorders even after controlling for potentially relevant risk factors," Cohrs and his colleagues wrote.

The findings cannot prove that smoking directly impairs sleep, since smokers may have other habits that could affect their shut-eye such as staying up late to watch TV or getting little exercise, Cohrs told Reuters Health in an email.

But there is also reason to believe the stimulating effects of nicotine may be to blame.

"If you smoke and you do suffer from sleep problems, it is another good reason to quit smoking," Cohrs said.

Poor sleep quality may not only make your waking hours tougher. Some studies have also linked habitually poor sleep to health problems like obesity, diabetes and heart disease.

The study included 1,071 smokers and 1,243 non-smokers who were free of mental health disorders, since those conditions may make a person both more likely to smoke and more vulnerable to sleep problems.

The researchers used a questionnaire that gauges sleep quality. Overall, more than one-quarter of smokers had a score than landed them in the category of "disturbed" sleep, meaning they had a high probability of insomnia.

Many things can affect sleep quality, and Cohrs's team was able to account for factors such as age, weight, and alcohol abuse. Yet smoking was still linked to poorer sleep quality.

It's still possible there are other things about smokers that impair their sleep, but Cohrs said he thinks the most likely culprit is nicotine - and the prospect of better sleep could provide smokers with an additional reason to quit.
