Why does the human body wake up?

Question

I know when a human is sleeping, the human body is in form of hibernation. But why does it decice to wake up, after about 8 hours or so (Apart from a person needing to get up to things)?

Answer 1

inside your head you have three parts to your brain, and the brain runs at four speeds. slow for rest, medium for data storage, fast for awake states, and super fast in emergencies.

the oldest part is at the base of the skull ( 5%) near the spinal cord, it is reptilian in design, a throw back to our evoloution, and was designed to work on a cold blooded animal. this keeps the body functions working, and works on a 28 hour clock, which is reset with sunlight, from a time when our evolountary ancestors used the sun to warm up.

The mamial core, which overrides this brain (15%), is our short term memory, and works on a 28 day cycle, in tune with the luna cycles. it operates the maintenance system of our body, rplacing the fluids and cells in our body, and also stores the vital data we need for emergency reactions. all data is held in it, whilst it awaits sorting into the last part the nono-cortex, the grey matter, which makes up the 80% of the brain. but this part controls body temprature, and puts us into sleep mode, controls sleep and dreams, and wakes us up again

THE NANO-CORTEX works on a weekly routeen, and provides us with the sociual stimulus to make us wait for certain days of the week, it is also the main storage and data processing centre.

during sleep the brain takes about 3 hours to deep sleep, where it does the maintenence at slow speed, then 3 hours to do the REM (rapid eye movement) sleep where the memory is relived at medium speed (dreams) and indexed, stored or even backed up into long term memory. it takes about 40 minutes to slip into sleep with some silly dreams of our day, which we may remember, and about 30 minuted to switch from deep to REM sleep. finally we are slowly brought out of sleep with light dreams again, if jolted awake, we may remember a dream, or just be groggy, as the brain is not workiung at the right frequency to activly think for a few seconds.

i totally second 'shyfello's' response! Proverbs 1:7. reverance for the Lord is the only way to attain true wisdom! it's scripture.

alternatively, it could possibly be the result of the interaction between distinct areas in the brain (e.g. vlpa ventro lateral preoptic area) and a number of hormones including orexins, histamines, achetylcholine, and a couple others.

basically works via disinhibition, so both areas - for ease we'll say waking areas and sleeping areas - cannot be activated at the same time, deficits in either areas cause sleeping disorders for example narcolepsy (when we suddenly fall asleep) can be caused when there are too much orexinergic (or sleep promoting) neurons in the brain.

so that was the intro! basically to put it simply, when we sleep 'sleeping areas' in the brain are inhibited and while they are inhibited, other neurons like the orexins will build up. when a certain amount of such neaurons are detected in the brain we wake up.

if you ask Jesus, it makes more sense ;)
