from the urls-we-dig-up dept
It's still a bit mysterious why sleep is so necessary. Some people seem to need more than others, and there's at least one guy who claims he doesn't need sleep at all. Here are just a few more tidbits on the topic of sleeping, for all of you sleepyheads and night owls.
- Sleeping for only 2-3 hours per day with a polyphasic sleep schedule sounds like a difficult regimen to maintain. This diary of a polyphasic sleep experiment ends after about 5 months, and it's not too hard to imagine why more people don't try it. [url]
- About 1-2% of the population consists of "long sleepers" who need at least 10 hours of sleep at night in order to function normally. Sleep duration varies widely and could involve genetic factors. (Surprise!) [url]
- If you think you're special and don't need as much sleep as anyone else, maybe you are or maybe parts of your brain are shutting down while you're awake and you don't even realize it. At least in sleep-deprived rats, scientists can observe "local sleep" where parts of these rat brains shut down while the rat is still conscious. [url]
