If you're not getting a good night's sleep, your laptop, smartphone or tablet are to blame, according to a study from the National Sleep Foundation (NSF). The survey found that 95 percent of those polled use devices with bright screens in the hour before bed, while 60 percent of them say that they have sleep-related problems such as snoring or still feeling tired in the morning."Unfortunately, cell phones and computers, which make our lives more productive and enjoyable, may be abused to the point that they contribute to getting less sleep at night, leaving millions of Americans functioning poorly the next day," said Russell Rosenberg, Vice Chairman of the NSF.
The NSF poll found Americans report very active technology use in the hour before trying to sleep, whether it's using a laptop, smartphone or tablet. "Artificial light exposure between dusk and the time we go to bed at night suppresses release of the sleep-promoting hormone melatonin, enhances alertness and shifts circadian rhythms to a later hour -- making it more difficult to fall asleep," said Charles Czeisler, Ph.D., MD, Harvard Medical School and Brigham and Women's Hospital.
