The myth of the eight-hour sleep

Should we really be sleeping for eight hours non-stop or might it not be as healthy as it seems ?
New evidence suggests waking up in the middle of the night and being unable to get back to sleep might actually be beneficial and that the idea of a single eight-hour sleep may be unnatural. A growing amount of historical evidence has also challenged our sleeping patterns by revealing that people once slept at night in two distinct chunks of sleep as oppose to a single long snooze.
In 2001, historian Roger Ekirch of Virginia Tech published a seminal paper, drawn from 16 years of research, revealing a wealth of historical evidence that humans used to sleep in two distinct chunks.

On weekdays I sleep 5-6 hours a night and I feel more rested throughout the day than on the weekends where I sleep 7-8.

I sleep around 8-12 hours a day and i love it. Also it makes me smarter. You do know the longer you sleep the smarter you get, right? No way dude, I know people who sleep a whole lot (they're French, don't work and get money for free) and they're dumber than the dirt on my boots. When I got divorced I was still a full time student and I had to work full time at the same time. I had to sleep in two periods of 2 and half hours, one in the afternoon and one at 3:30 am. I did my best work during that period.

I usually get about 7 hours of sleep per night. I have sleep apnea and understand the importance of 'real' sleep. I've read many articles on sleep. I've even found some articles that state that the body can actually 'bank' sleep. I like to take naps on the weekends because I never know how much true sleep I will get at night. Without my CPAP machine I stop breathing for more than 30 seconds at a time, an average of 29 times per hour. When a person that has sleep apnea has that happen they can actually be on the edge of slipping into a therapeutic sleep state and all of sudden stop breathing. T... [More]

I usually get about 7 hours of sleep per night. My CPAP machine (Darth Vader mask as I refer to it so I don't think I look so dorky while wearing it in my sleep) has really helped. Dear Darth, Well said! I am a 17 cm3 settings sleep apnea kind of guy! I would wake as if hit by a Mac truck during the night, being so tired from sleeping. My attempts to catch a breath led to knots in my hair every morning. I guess I would spin on my head or some other kind of break dancing! lol Anyway, thanks for spotting the good moment for a little educational treatise!

I need about 6 hours to feel ok and about 7 to feel good. I actually can't sleep beyond 7 hours even if I want to. However, I do sleep 6 to 7 hours without fully waking up. It's kind of interesting how people vary in sleep patterns.

17 cm3 is pretty high isn't it? I think I'm only set at 8 cm3. I try to educate all of my friends about sleep apnea. It's more common than people think. I even had my sister go get a sleep study done. The CPAP helped me immensely but I was still lacking energy. Turns out I have an extremely low Vitamin D level as well. So now I take 5000 ui per day of Vitamin D and I'm noticing a difference. Yeah, when my wife's fifth meditarsol in her left foot was broken--Dancer's Break the call it--the pedodiatrist said he was glad she was taking mega-calciun with vitamine D so the calcium would be abundent...

Insomnia is one of the worst things that can ever happen to you.

The '8' Hour sleep thing is bull****. You wake up in the night because you're body and mind tells you too because after that you've finished you're sleep. No matter what time it is.
