Less Than 8 Hours of Sleep May Not Hurt Health

A new study suggests that people who sleep 8 hours or more a night, or less than 4 hours, have a slightly higher risk of dying in a given time period than those who get 6 and 7 hours of shut-eye.

However, the researchers note that they can't be sure why some of the study subjects had longer or shorter sleep periods, and there's no evidence that sleep patterns-or changing them-can truly influence mortality risk.

Some sleep experts, including those at the National Sleep Foundation (NSF), agree.

Although the study reports data that is of interest, limitations in the study methodology restrict the conclusions that can be reached, particularly about the amount of sleep needed to sustain an individual's health, safety and well-being.

In the study researchers examined the findings of a previously conducted study that included, among other things, data on the sleep habits of 1.1 million people men and women between the ages of 30 and 102.

The study subjects, friends and family members of American Cancer Society volunteers, were interviewed in 1982 about diet, exercise, sleep and health problems and then followed up 6 years later.

Participants who reported sleeping 8 or more hours or less than 4 or 5 hours a night experienced a slightly higher chance of dying-at least a 15% increase in risk -- within that time compared with those who slept 7 hours a night.

Interestingly, only one in a thousand slept at the lower end of the time scale.
Furthermore, the researchers report that insomnia was not associated with excess mortality, although the use of a prescription sleeping pill was also associated with a slightly increased risk of dying during the six-year period.

The study does seem to indicate that fewer than 8 hours of shuteye a night are not necessarily detrimental to health.

The study was not designed to answer why sleeping longer may be deleterious or whether people could extend their life spans by sleeping less. It is possible that people who sleep longer tend to suffer from sleep apnea, a condition in which impaired breathing puts stress on the heart and brain. The need for sleep is akin to the need for food, in that getting less than people want may be better for them.

While agreeing that the risk of dying from reduced sleep is low, he added, "It's hard to know if we shouldn't be worried about five hours of sleep -- if you are talking about being able to drive a truck a thousand miles the next day, being able to concentrate, make important decisions, that's a whole other story."

The average American sleeps 7 hours on weekdays, according to the 2001 Sleep in America Poll (conducted by the National Sleep Foundation). The new study shows that it is quite safe to sleep five, six, or seven hours a night, and people who sleep less than eight hours do not need to worry.

The study's findings may lead the public to be less concerned about insomnia -- a sometimes serious condition marked by an inability to sleep. Even mild sleep deprivation is associated with increased daytime sleepiness, which may lead to adverse outcomes, such as accidents.

Insomnia is associated with impaired quality of life, functional impairment, physical symptoms, and coronary heart disease. Sleep is not bad for you and insomnia is not good.

Sleeplessness produces health consequences that were not measured in the study. The amount of sleep you get impacts how alert you are, your risk for accidents, how you perform at work and school. There's much more to life than how long you live.

The National Sleep Foundation emphasizes that substantial research serves as the basis for the recommendation that adults obtain an average of seven to nine hours of sleep each night.

The group notes that individuals will require different amounts of sleep and that if someone sleeps 8.5 hours a night and feels alert and energetic, it would be incorrect to reduce sleep time based on the study.
Very intresting, though one of my New Year's resolutions was to get at least 8hours of sleep a night.

For the past year or two I've needed something like 12 hours of sleep to feel the way I used to when I had 4 hours of sleep =/

Then again, the longer I sleep, the more interesting my dreams become, so I'm not complaining.

I can sleep 1 hour and still be awake at school. Well, I can go "offline" in maybe 15 mins on school but my teacher screams so much that I can't sleep...

Interesting, but eh, I get around 6-4 hours asleep on the weekdays, and in my psychology class, I learned that that kind of sleeping can make you sleep deprived.

Given the symptoms of sleep deprivation, preeeeetty sure I'm sleep deprived =(

Then sleep more?

I used to be able to sleep 3 or 4 hours a night, wake up and feel completely energized. I don't know what the deal is now, but I'm hoping it's just teenage crap. I miss being able to be awake basically all day.

Well there are a few shows, such as the Daily Show and Colbert report I like to watch when they come on, and chances are my homework ain't done yet so I'm still up finishing that. And I don't usually like to go be before 12:30 since I feel like I'm somehow wasting time by sleeping when I could be doing something else.

Thing is I am not tired during the day besides A Block, but then I seem to get drowzy all of the sudden when I get home.

I love sleeping. In fact, if I weren't trying to get myself back into my school routine, I would be asleep now.

When I'm working, I like to get 8 hours each night, but for school, I seem to get by on 6 or so. Any less and I'll start sleeping through my alarm in the morning.

I dont trust these studies too much, but i love sleeping. Its just a pain in the ass to wake up early.
This all makes me remember that we once had a Psychology class where we were supposed to sleep. The teacher put a tape rolling where a very anemic voice was constantly saying things like "You feel very relaxed.", "Youre becoming tired." all the time.
Of course i couldnt sleep, because the school benches were so uncomfortable. So there i was for 2 hours listening to anemic voice...
