What makes us tired?

[TTG]

Is there any reason we have to sleep 6-8 hours every night just to get over what we do in the day? That is around 1/3 of our lives!

Kids, stress, work, stress, kids and stress !

When you get a good answer to that I'd like to know why I have to sleep 6-8 hours every day just to get over what I do all night?

There are a number of theories.

One of the most interesting recent ones is that it keeps us out of trouble.

Once you have met your daily requirements - food, water, shelter etc. additional time being out and about increases your probability of meeting a predator, falling off of a cliff or generally meeting a situation to reduce your chance of being killed prior to a sucessful reproduction.

Sleep therefore evolved to give us all a strong need to tuck ourselves out of the way until our body needed something more.

Not saying this is the right explanation - but it is interesting

Mibn - maybe you should wear boxing gloves!

[mibn2cweus]

heathfield, Boxing glove(s)? Where does the other one go?

[TTG]

Thanks Jake. Wonder when mankind will lose this ancient requirement?

Tiredness is the brain's way of telling the body that it is time for sleep when injuries are repaired, growth and regeneration occurs, and the information gathered over the day is re-organised into certain cerebral parts. You can fool your brain by taking 'uppers' and think you feel fine, but you are really harming yourself as the muscles are unable to process the access acid when you do eventually sleep.

A regular sleep regime is therefore good to maintain a healthy body and very necessary for an attentative mind.

Politics! Especially listening to the MP's in the house of commons drone on and on for several weeks about goodness knows what.
