Sleep is overrated - I need about 5 to 6 hours tops a night. I can’t 'lie in' and I wake up in the morning ready for a 2 hour debate on the pros and cons of snowflake schemas in data warehouse design! My brain is buzzing the minute I wake up.

Mr P is 9 hour a night man - more on the weekend and brain function doesn’t really start till around noon.

I go to bed after him and wake up before him. And I'm awake as soon as the sun comes up in summer - so I end up sleeping less in summer than winter.

My husband, daughter, cats & guinea pigs ALL sleep more than me!
I have no trouble getting to sleep - I just don’t do much of it.

But why do you need any ?


why is it so crucial ?

Sleep is also time for immune system to regroup and get ready for another day fighting baddies.

Well, I read the linky that Moscow Mule provided and its a very good theory. But there were a lot of ifs, buts and maybes.

A good working theory though

Not this one. It's something thats always fascinated me, but I dont have any clue

I love sleeping.... it's one of my fave things to do. I am not a morning person and when I am tired I am seriously cranky!!!

[thelace]

I don't get much choice in the matter....

Brain gets tired and turns off, eyes shut!

No concious decision made.

Why don't you sleep on it?

Sleeping does seem like a huge waste of time. Mind you, in my case, so is being awake, to be honest.

[Moscow Mule]

Right, so it's a brain thing, nothing to do with being tired. Good.
So what is down time ? what exactly is going on here ?

What Does Sleep Do For Us?

Although scientists are still trying to learn exactly why people need sleep, animal studies show that sleep is necessary for survival. For example, while rats normally live for two to three years, those deprived of REM sleep survive only about 5 weeks on average, and rats deprived of all sleep stages live only about 3 weeks. Sleep-deprived rats also develop abnormally low body temperatures and sores on their tail and paws. The sores may develop because the rats' immune systems become impaired. Some studies suggest that sleep deprivation affects the immune system in detrimental ways.

Sleep appears necessary for our nervous systems to work properly. Too little sleep leaves us drowsy and unable to concentrate the next day. It also leads to impaired memory and physical performance and reduced ability to carry out math calculations. If sleep deprivation continues, hallucinations and mood swings may develop. Some experts believe sleep gives neurons used while we are awake a chance to shut down and repair themselves. Without sleep, neurons may become so depleted in energy or so polluted with byproducts of normal cellular activities that they begin to malfunction. Sleep also may give the brain a chance to exercise important neuronal connections that might otherwise deteriorate from lack of activity.

Deep sleep coincides with the release of growth hormone in children and young adults. Many of the body's cells also show increased production and reduced breakdown of proteins during deep sleep. Since proteins are the building blocks needed for cell growth and for repair of damage from factors like stress and ultraviolet rays, deep sleep may truly be "beauty sleep." Activity in parts of the brain that control emotions, decision-making processes, and social interactions is drastically reduced during deep sleep, suggesting that this type of sleep may help people maintain optimal emotional and social functioning while they are awake. A study in rats also showed that certain nerve-signaling patterns which the rats generated during the day were repeated during deep sleep. This pattern repetition may help encode memories and improve learning.

do sharks sleep ?

Not sure if it's sharks, but some animals can switch off one side of their brain and operate with the other side, working shifts as it were. That is something that scientists could usefully work on duplicating in humans. Sleeping does seem like a huge waste of time. Mind you, in my case, so is being awake, to be honest.

Blooming heck. This forum.

OK, Let me rephrase the question.

After a frantic evenings sh@gging, why do some people need to close their eyes on the couch to avoid looking at their partner for five hours, whilst others need to close their eyes on the couch to avoid looking at their partner for ten hours ?

In your scenario, I'd say that the time spent sleeping would be inversely proportional to the size of your partners tits.

we get a rest from you.

[EternalOptimist]

Yes, but it's not the same as being unconscious. You brain needs a bit of down time every day, some folk are conditioned to need less than others, but we all need a bit.
