Amazing Facts about Sleep



12.50 pm..huarghh..so sleepy. Now it is time to sleep, but I need to finish up my blog to ensure all people get a right data and information. Hm..I think this topic is quite interesting to share to you all. Here i list down all facts about sleep that categorized as amazing facts you never heard before. Take a moment to
read this as your references.
  1. Anything less than five minutes to fall asleep at night means you’re sleep deprived. The ideal is between 10 and 15 minutes, meaning you’re still tired enough to sleep deeply, but not so exhausted you feel sleepy by day.
  2. A new baby typically results in 400-750 hours lost sleep for parents in the first year.
  3. Tiny luminous rays from a digital alarm clock can be enough to disrupt the sleep cycle even if you do not fully wake. The light turns off a “neural switch” in the brain, causing levels of a key sleep chemical to decline within minutes.
  4. ]To drop off we must cool off; body temperature and the brain’s sleep-wake cycle are closely linked. That’s why hot summer nights can cause a restless sleep. The blood flow mechanism that transfers core body heat to the skin works best between 18 and 30 degrees. But later in life, the comfort zone shrinks to between 23 and 25 degrees - one reason why older people have more sleep disorders.
  5. Ten per cent of snorers have sleep apnea, a disorder which causes sufferers to stop breathing up to 300 times a night and significantly increases the risk of suffering a heart attack or stroke.
  6. Snoring occurs only in non-REM sleep.
  7. Teenagers need as much sleep as small children (about 10 hrs) while those over 65 need the least of all (about six hours). For the average adult aged 25-55, eight hours is considered optimal.
  8. Some studies suggest women need up to an hour’s extra sleep a night compared to men, and not getting it may be one reason women are much more susceptible to depression than men.
  9. Experts say one of the most alluring sleep distractions is the 24-hour accessibility of the internet.
