Interesting facts about sleep

This article discusses a few interesting facts about sleep.

A proper sleep cycle ensures the well-being of our physical and mental health, but surprisingly we do very little to maintain our sleep cycle. These intriguing facts about sleep will motivate, if not coerce, you to take your 'sleep' more seriously.

· Economizing on sleep may lead to shrinking of brain
It's a fact that human brain does shrink with age, but people who sleep for less duration are prone to increased rate of reduction. The fact is backed by a research. There are many factors like cholesterol levels, physical activity which are linked to the rate of change in brain volume over a period of time—and sleep has emerged as one of the important factors. A study carried out by Claire Sexton, DPhil, lead researcher found that people who sleep less clocked a higher rate of decline in the size of the frontal, temporal, and parietal lobe areas of the brain.

· Less sleep may lead to or speed up Dementia 
Researchers and doctors promote sleep for an enhanced memory. Now studies have found out that less sleep may lead to dementia or accelerate the emergence of this disease. More research is needed to establish if lack of sleep actually causes dementia; till then, the best thing to do is to relax and sleep for sufficient number of hours.

· Brain makes decision while we are asleep
Remember those times when you were irked to make a decision but couldn't make it. You closed your work and went to sleep. And when you woke up you realized that you've made the decision. Ever wondered why and how? This is a result of your brain that was busy organizing information, processing data and clearing up unnecessary information while you were asleep. The fact was brought to light in a study that was done by a team of French and UK researchers. In this research, a group of adults were given a task of word classification, one when they were awake, and the other while they were asleep. The researchers found that same pattern of brain activities were happening when individuals were presented with even more words while they were asleep. This perfectly explains why we respond when someone calls out our name while we are asleep.

· Sleep Apnea can be treated better with the help of family
Sleep apnea is a sleep disorder which is characterized by breathing pauses or breaks during sleep. There are two types of sleep apnea: obstructive sleep apnea and central sleep apnea. The problem can be mild or severe, based on how often your lungs don't get enough air. Continuous positive airway pressure (CPAP) is the best method for treating sleep disorders. Family support is vital to make a person adhere to this treatment. Studies suggest, people who rated their family relationship quality higher, adhered to CPAP treatment more closely.

· Night birds have more difficulty sticking to an exercise routine
Early risers are found to be disciplined when it comes to exercise routine. It is quite easy for them to get out of bed early morning, and go out for jogging, running, or other exercises. While on the other hand, night owls find it troublesome to stick to an exercise routine. For them getting out of bed early morning is next to impossible. In a study, it was found that night owls generally spent their time sitting aimlessly, feel like doing nothing and gave excuses for not being able to exercise like insufficient number of hours in the day.

· Sleeping with a pet alongside messes your sleep
The world is filled with pet lovers. Out of these pet lovers some even go to an extent where they share bed with their pets. This may sound wonderful but it actually affects your sleep. A research presented at the annual meeting of the Associated Professional Sleep Societies, found that 30% of pet owners who shared bed with their pets get interrupted sleep as they had to get up at least once in the night due to the barks, meows, tail wags, and more. So, overall this idea of sharing bed, however cute it sounds, will disrupt your sleep and affect your health.

Study: Autistic children with pets are more assertive

A study shows that having pets acts as a social catalyst for children, especially those with autism.

Dogs and other pets play an important role in individuals' social lives, and they can act as catalysts for social interaction, previous research has shown. Although much media attention has focused on how dogs can improve the social skills of children with autism, a University of Missouri researcher recently found that children with autism have stronger social skills when any kind of pet lived in the home.

"When I compared the social skills of children with autism who lived with dogs to those who did not, the children with dogs appeared to have greater social skills," said Gretchen Carlisle, research fellow at the Research Center for Human-Animal Interaction (ReCHAI) in the MU College of Veterinary Medicine. "More significantly, however, the data revealed that children with any kind of pet in the home reported being more likely to engage in behaviors such as introducing themselves, asking for information or responding to other people's questions. These kinds of social skills typically are difficult for kids with autism, but this study showed children's assertiveness was greater if they lived with a pet."

Pets often serve as "social lubricants," Carlisle said. When pets are present in social settings or a classroom, children talk and engage more with one another. This effect also seems to apply to children with autism and could account for their increased assertiveness when the children are living in a home with pets, Carlisle said.

"When children with disabilities take their service dogs out in public, other kids stop and engage," Carlisle said. "Kids with autism don't always readily engage with others, but if there's a pet in the home that the child is bonded with and a visitor starts asking about the pet, the child may be more likely to respond."

Carlisle also found that children's social skills increased the longer a family had owned a dog, yet older children rated their relationships with their dogs as weaker. When children were asked, they reported the strongest attachments to smaller dogs, Carlisle found.

"Finding children with autism to be more strongly bonded to smaller dogs, and parents reporting strong attachments between their children and other pets, such as rabbits or cats, serves as evidence that other types of pets could benefit children with autism as well," Carlisle said.

Carlisle surveyed 70 families who had children with autism between the ages of 8 and 18.The children were patients at the MU Thompson Center for Autism and Neurodevelopmental Disorders. Almost 70 percent of the families that participated had dogs, and about half of the families had cats. Other pets owned by participants included fish, farm animals, rodents, rabbits, reptiles, a bird and even one spider.

"Dogs are good for some kids with autism but might not be the best option for every child," Carlisle said. "Kids with autism are highly individual and unique, so some other animals may provide just as much benefit as dogs. Though parents may assume having dogs are best to help their children, my data show greater social skills for children with autism who live in homes with any type of pet."

Pets may be disturbing your sleep

Pets may be disturbing you while you sleep and causing you to not get quality sleep.

Rest assured, there may be a good reason you're dog-tired.

While countless pet owners peacefully sleep with a warm pet nearby, a new Mayo Clinic study, presented this week at the 29th Annual Meeting of the Associated Professional Sleep Societies, finds an increase in the number of people experiencing sleep disturbances because of their pets.

A previous Mayo Clinic study published in 2002 reported that of patients who visited the clinic's sleep center and owned pets, only one percent reported any inconvenience from their pets at night. The new study shows a larger number of patients -- 10 percent in 2013 -- reported annoyance that their pets sometimes disturbed their sleep.

"The study determined that while the majority of patients did not view their pets intolerably disturbing their sleep, a higher percentage of patients experienced irritation -- this may be related to the larger number of households with multiple pets," says Lois Krahn, M.D., Mayo Clinic psychiatrist and author of the study. "When people have these kinds of sleep problems, sleep specialists should ask about companion animals and help patients think about ways to optimize their sleep."

Between August and December 2013, 110 consecutive patients at the Mayo Clinic Center for Sleep Medicine in Arizona provided information about pets at night as part of a comprehensive sleep questionnaire. Questions covered the type and number of pets, where the animals slept, any notable behaviors and whether the patient was disturbed. The survey showed that 46 percent of the patients had pets and 42 percent of those had more than one pet. The most popular pets were dogs, cats and birds.

The disturbances by pets that patients reported included snoring, whimpering, wandering, the need to "go outside" and medical needs.

"One patient owned a parrot who consistently squawked at 6 a.m.," Dr. Krahn says. "He must have thought he was a rooster."
