Better bedtime reading. Adult volunteers who used electronic readers or tablets, such as iPads, for four hours before bedtime had a harder time falling asleep…got less rapid eye movement (REM) sleep…and felt less alert and rested the next morning than when they spent the same amount of time reading a printed book. Why: Tablets emit blue light directly into the reader’s eyes, which can suppress the sleep hormone melatonin and disrupt the circadian clock.

A long-term study of initially healthy 65-year-olds found that those who slept the least (about five hours or less without waking) tended to have fewer neurons (brain cells) in a part of the brain that controls sleep. Also: Many in the study who developed Alzheimer’s disease were those who had fewer neurons and less sleep. To protect your brain: Keep neurons healthy with good sleep habits, and seek treatment if you suspect you may have a sleep disorder.
In a recent study, according to Peter Liu, PhD, principal investigator, from the biomedical research institute, showed that a group of 19 non-diabetic men who usually sleep about six hours a night during the week spent three days in a sleep lab where they slept 10 hours every night, their insulin sensitivity improved, lowering their risk for type 2 diabetes. Regular sleep just like good eating habits, keeps insulin levels balanced. If you get less than seven hours of sleep a night during the week, plan to get more.
According to bottom line health, in a study of 4,548 adults, those with the greatest variety in what they ate throughout the day slept for seven to eight hours each night, while those with the least variety slept for fewer than five hours. Shorter sleep times were also related to low intake of water and common antioxidants, such as vitamin C and lycopene, commonly found in fruits and vegetables.
Even if the cause of your sleeplessness is properly treated, poor sleep habits might need to be managed separately. These techniques can help.
Set a bedtime and wake-up time. A schedule teaches your body to expect sleep at a certain time each night.
Curb napping. A 30-minute snooze before 3p.m. can help make up for lost sleep, but later naps could hinder sleep at night.
"I often take melatonin to help me sleep me sleep. Will this cause my body to stop producing the hormone or result in any other side effects?"
No. Melatonin supplements have not been shown to stop the pineal gland from producing natural melatonin. Levels of melatonin, a neurohormone naturally produced by the pineal gland in the brain, rise during the night and dip in the morning. In some people melatonin supplements can induce sleepiness at bedtime and help them fall back asleep when taken during nighttime awakenings. A low dose (0.5 mg) is often effective for jet lag and other body-clock disorders.
According to the Lee Swanson Research Update there is a significant correlation between excessive daytime sleepiness, race, and low vitamin levels according to new research. The new study finds progressively higher levels of daytime sleepiness were correlated inversely with progressively lower levels of vitamin D. Led by Dr. David McCarty FROM Louisiana State University Health Sciences Center suggests that people with lower levels of vitamin D may be at increased risk of high levels of day times sleepiness and other sleep disorders.
