I think they sleep as much, just spread out through the day. Which would be a real pain in the ass to get things done. There is a reason why its a disorder and not commonplace.
The premise of this is pretty cool. When you think about most mammels, they do not sleep for 8 hours while remaining away for 16. Anyone who has kids knows that babies don’t abide by our social sleep cycle. There are different ways to slice the day between awake and sleep, but I read about those who sleep for 1 hour and remain awake for 3 to 5. Effectively you’d sleep 4 to 6 hours a day in intervals. Not sure how you’d really do it unless you worked for yourself and could get by at unconventional hours.
Our sleep cycle is governed by biology. No matter what these people try to claim when they reduce sleep to an addition problem, it doesn’t work that way: http://en.wikipedia.org/wiki/Circadian_rhythm
Melatonin is absent from the system or undetectably low during daytime.
Light resets the biological clock in accordance with the phase response curve (PRC). Depending on the timing, light can advance or delay the circadian rhythm.
Going against the cycle has some known consequences, health wise. I’m sure there are more we don’t know yet that require a long period of ineffective sleep to manifest.
I take sleep very seriously. It was one of the things I was actually interested in during my biology and neuroscience classes in undergraduate.
You have to get REM sleep. If you can get a good amount of it during these short periods, great. If not, you’ll probably be a sleepless traveling consultant dealing soap and starting a fight club.
I got a CPAP machine a few years ago, and it literally changed my life. You have no idea how important good sleep is until you start getting good sleep.
“Exposure to sleep and darkness in the morning resulted in phase delays, whereas exposure in the evening resulted in phase advances relative to controls. Afternoon naps did not change circadian phase.”
Try avoiding artificial light in the evenings for a month or so. It’s amazing (from what I hear, I’ve been doing it so long I just get friends to convert. And they all think I’m crazy)
Originally, I thought I had ADD, because I had extreme difficulty focusing on anything. (This is when I was attending my Top-1 MBA program, and it was extremely demanding, even for those of us with an IQ of 180.)
After going to the psychologist, he said that he didn’t think it was a cognitive problem. He referred me to the sleep specialist, because the symptoms of sleep apnea and ADD can be very similar. Basically, when you don’t get good sleep, your brain never “recovers”, and it’s harder to focus on stuff.
Yes, I did a sleep study.
And waking up in the middle of the night isn’t the real enemy. If you’re waking up because you woke out of REM or need to pee, that’s different. But if you’re choking on your soft palate, then you need to see a doctor. The problem gets exacerbated if you’re overweight (so I’ve heard–not that I’m fat or anything).
Waking in the middle of the night canactually a very good sign, if its for the right reasons. It used to be wayyy more common before Edison’s curse. It’s how we seem designed to sleep. From Jessa Gamble’s TED talk on sleep (a journalist that covers this topic):
So, what would our natural rhythm look like? What would our sleeping patterns be in the sort of ideal sense? Well, it turns out that when people are living without any sort of artificial light at all, they sleep twice every night. They go to bed around 8:00 p.m. until midnight and then again, they sleep from about 2:00 a.m. until sunrise. And in-between, they have a couple of hours of sort of meditative quiet in bed. And during this time, there’s a surge of prolactin, the likes of which a modern day never sees. The people in these studies report feeling so awake during the daytime, that they realize they’re experiencing true wakefulness for the first time in their lives.
If you get >= 7 hours of sleep per night but are tired a lot, I would recommend the sleep study. It cost me about $400 with insurance that didn’t cover it and takes one night of staying at the sleep clinic. I had a mild case of sleep apnea, about 15 apneas an hour. Best money I ever spent was getting that fixed. I also have insomnia and difficulty getting to sleep and recommend intermezzo for that. I’ve tried every sleep drug on the market and that is hands down the best for me.
