Sleep: Post #7--Sleep deprivation.

Sleep Deprivation:  In 1950, we got 8 hours, but today we sleep only 6.5. Teens need 9 hours, but only get 5.  Shift work: Body clock does not adapt—quality of sleep is poor—simulates jet lag. A result can be micro-sleep—involuntary sleep. Thirty-one percent (31%) of drivers will fall asleep at the wheel in their lifetime, and over 100,000 accidents a year are associated with sleep at the wheel. Poor judgment due to sleep deprivation contributed to the Space Shuttle Challenger disaster. Sleep deficits account for impulsivity, poor judgment, poor memory and poor creativity.
