Patient discussion about counteraction

Q. what are the affects of sleep deprivation, and can I counteract them? I’m a college student and I’ve been sleeping for 5-6 hours a night for the past month…what symptoms should I expect? And how can I counteract them?

A. I studied this just 2 days ago:

Studies on sleep deprivation are actually beginning to show that people do not require as much sleep as traditionally taught. While sleep deficits effect first auditory acuity, and can even cause people to go into what are called microsleeps, researchers are finding that when people are being deprived of sleep they actually sleep more efficiently (spending more time in stages 3 and 4 of sleep) The problem is that people do not train themselves properly to shortened sleep periods, thus stuggle to adapt when they cannot receive the customary eight hours. Ideally, with adequate control and preperation, people can sleep for 4 hours a night and be fully cognatively functional.

Just thought you'de find that interesting

See Pinel's chapter on Sleep in his text "Biopsychology" for more. (Pinel, 2009)
