we and our sleep...

I'm a kind of person who never mind about sleeps... but it affected me a lots... here some facts abt our sleep...
  • Seventeen hours of sustained wakefulness leads to a decrease in performance equivalent to a blood alcohol-level of 0.05%.
  • Scientists have not been able to explain a 1998 study showing a bright light shone on the backs of human knees can reset the brain's sleep-wake clock.
  • Dreams may not serve any purpose at all but be merely a meaningless byproduct of two evolutionary adaptations - sleep and consciousness.
  • Exposure to noise at night can suppress immune function even if the sleeper doesn’t wake. Unfamiliar noise, and noise during the first and last two hours of sleep, has the greatest disruptive effect on the sleep cycle.
  • After five nights of partial sleep deprivation, three drinks will have the same effect on your body as six would when you've slept enough.
  • Snoring occurs only in non-REM sleep... meaning of REM
  • Experts say one of the most alluring sleep distractions is the 24-hour accessibility of the internet.
  • The record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.
