WHY DO WE NEED SLEEP?

Scientists have proposed the following theories on why humans require sleep:

  • Sleep may be a way of recharging the brain. The brain has a chance to shut down and repair neurons and to exercise important neuronal connections that might otherwise deteriorate due to lack of activity.
  • Sleep gives the brain an opportunity to reorganize data to help find a solution to problem, process newly learned information and organize and archive memories.
  • Sleep lowers a person’s metabolic rate and energy consumption.
  • The cardiovascular system also gets a break during sleep. Researchers have found that people with normal or high blood pressure experience a 20 to 30% reduction in blood pressure and 10 to 20% reduction in heart rate.
  • During sleep, the body has a chance to replace chemicals and repair muscles, other tissues and aging or dead cells.
  • In children and young adults, growth hormones are released during deep sleep.
  • When a person falls asleep and wakes up is largely determined by his or her circadian rhythm, a day-night cycle of about 24 hours. Circadian rhythms greatly influence the timing, amount and quality of sleep.

OKAY.
I AM JUST REALLY TRYING TO CONVINCE MYSELF TO SLEEP.
DOING RESEARCH ALSO NO USE.


I HAVE BEEN SURVIVING ON A FEW HOURS OF SLEEP A DAY.
DON'T ASK WHY.
