Importance of Sleep

In last week's 60 minutes+ episode, a UC berkerley researcher said that sleep deprivation is equal to food deprivation. According to him, from an evolution pt of view, why we have to sleep if we will become so vulnerable when we are asleep.
That implies the importance of sleep.

Other researchers show how lack of quantity and quality sleep will affect our memory, reflexes, emotions and even sex life.
Through a CT scan image, the area in brain that controls emotion is literally 'on fire' if not enough sleep and it ceases to communicate with the brain that controls your logic. Our emotions skip being the counter-checked by my our logical reasoning. We are more likely to do stupid things. Or even lead to psychiatric problems. (this I believe. I had an experience in a psy ward common room, yet don't worry, I was not the patient but a visitor). I overheard people sharing what kicked off their maniac episodes. All of them pointed to the lack of sleep for a period of time. I later dicsussed possible correlation of manic depression and sleep with my friends. So this 60 minutes program gave me more insight on what I previously observed.

Also, people who have been deprived of sleep overestimated their abilities just like drunkers.

Experts' advice: sleep through the night, sleep at least 7.5 to 8 hrs. Doing more does not mean that you are doing them smarter or efficiently.

Friends, sleep well.
