Why Do We Need Sleep?

People were going to find out one day!

We have erased all of the records, THIS NEVER HAPPENED!

Maybe chemicals get released to do simple things like repair, enhance, change cells e.t.c.

I remember watching a documentary about modafinil. That allowed people to function with minimal/no sleep. Prescription drug though, I don't think it's available for that purpose in the UK.

Heal, grow, recharge our body and brain and CNS and store memories?

 

[bainbridge]

How else would I go to dreamland?

Maybe it's to protect us from each other.

A question Ive always wondered about myself OP.

Its also the most time-wasting most irritating thing in life. I wish we didnt need it..but we do Such a waste of our lives lying there like a goat motionless.

Arent there some creatures that never sleep...is it sharks? Or can they sleep while swimming? I think they cant stop swimming or they croak (no fresh O2 water over gills).

Does anyone else suspect that the op might be britboy4321?

The tone of the post and even his name are very similar.

Why does our brain release a very powerful hallucinogenic (DMT) when we sleep to cause us to dream? And why would this drug also be found in plants which have no brains.

Not sure, but I believe the purpose of dreaming is to help the transfer of short term memory to long term memory.

Causes terrible mood swings.

I love sleepytime. It's the only time I can be an eagle soaring above the mountains and the only situation in which I will ever play like Liszt. Don't knock it!

Sharks don't sleep, nor can get cancer.

Random facts I remember from way back.

They do sleep, but one cerebral hemisphere per cycle, maintaining partial consciousness and activity at all times. Dophins do the same.

Cancer thing is urban myth. Sharks do get cancer just like every other animal on the planet.

So we can dream and know our future!!!!!

No, why do we have them?

Tide - The moons mavity pulls on the oceans (also the suns mavity, but not as much)
seasons - the earth is tilted a bit so as we orbit the sun either the northern or southern hemisphere is pointed at it.

I think that its a fact. No one can avoid it completely for forever.

Why do we need mavity, the moon, the sun and the northern and southern hemispheres though?

Ha I was going to post the same thing. His posts are completely unbelieveable (especially his latest one above). No one is that dense, he is just trolling.

We sleep because it's awesome!

Also, it's the ideal time for our brains to do some filing, let our bodies recover and fix itself. It can't really do that whilst we're awake as it's too busy using all our senses to help us do the activities that we're doing - which is why it needs us to lose consciousness or at least only have our deep subconscious active. Makes sense to me really.
