Why do humans actually need to sleep

[cannabis campbell]

I heard once (not sure if its true) that there was one man who 'never' slept because he believed that humans did not actually need to and we only do because we are used to it from when we are a baby..

What is the actual reason we need sleep is it because our brains need rest.. well say if you didnt sleep for 2 days or 4 days your brain would still work just as good right?

NO, after about 3 weeks of sleep deprevation you would die. Sleep is needed for the brain to organize the events of the day and for the body to reapir itself and to re-energize. You are no differant then a robot. Altho you dont run on battery power you do run on electro-chemical energy. After 3 days of sleep deprevation you will hallucinate and your heart starts to skip beats. After 5 days you have micro sleep sessions where your brain shuts down for a second or two. like it or not.
We are wired to sleep and if we dont then we break down.

I had a friend who stayed up for 92 hours. Around day three he said it felt like shrooming, and everything was all sped up. How'd he do it? Plenty of caffiene and Diablo II.

The most I have done is two days, and it sucked so bad. eventually you just want to crash and pass out

After a couple of days - It's one of the most uncomfortable things... every little bit of concentration is focussed on staying awake.

the reason we sleep is like why we smoke. try it; go to sleep. wake up in an hour and read this again, so i can say i told you so. we sleep because it feels good.

i dunno if they still do this, but some P.O.W (whichever war) were sometimes tortured with sleep deprivation. i read a book recently called "The Accidental Mind", it's all about the brain and one chapter was on sleep (and dreams).

So basically, yea you'll go mad if you are without sleep for too long. your body and your mind both need to regenerate. plus, regarding all the brain activity during sleep, it is possible, no, probable that your brain uses that time to collect your new memories and "move" them to other parts of your brain, for longterm storage.

cool, huh? :buzz_saw:

To use a computer analogy, sleeping and particularily REM is your brain's way of running a defrag program. All the information your mind has collected or created is organized.
Also, sleep is your brain's time to balance out it's serotonin levels and replenish its serotonin. Serotonin is very important for mood regulation, several forms of cognition and memory, and digestion.

So essentially, without sleep you'd go nucking futs.
