Why we need to sleep.

Sleep 'boosts brain cell numbers'

Myelin ensheaths nerves to protect them and speed up their signalling

Research looks at MS damage repair

Scientists believe they have discovered a new reason why we need to sleep - it replenishes a type of brain cell.

Sleep ramps up the production of cells that go on to make an insulating material known as myelin which protects our brain's circuitry.

The findings, so far in mice, could lead to insights about sleep's role in brain repair and growth as well as the disease MS, says the Wisconsin team.

The work is in the Journal of Neuroscience.

Dr Chiara Cirelli and colleagues from the University of Wisconsin found that the production rate of the myelin making cells, immature oligodendrocytes, doubled as mice slept.

The increase was most marked during the type of sleep that is associated with dreaming - REM or rapid eye movement sleep - and was driven by genes.

In contrast, the genes involved in cell death and stress responses were turned on when the mice were forced to stay awake.

Precisely why we need to sleep has baffled scientists for centuries. It's obvious that we need to sleep to feel rested and for our mind to function well - but the biological processes that go on as we slumber have only started to be uncovered relatively recently.

Growth and repair
Dr Cirelli said: "For a long time, sleep researchers focused on how the activity of nerve cells differs when animals are awake versus when they are asleep.

"Now it is clear that the way other supporting cells in the nervous system operate also changes significantly depending on whether the animal is asleep or awake."

The researchers say their findings suggest that sleep loss might aggravate some symptoms of multiple sclerosis (MS), a disease that damages myelin.


Scientists are only just unravelling the precise mysteries of why we sleep
In MS, the body's immune system attacks and destroys the myelin coating of nerves in the brain and spinal cord.

Future studies could look at whether or not sleep affects the symptoms of MS, says Dr Cirelli.

Her team is also interested in testing whether lack of sleep, especially during adolescence, may have long-term consequences for the brain.

Sleep appears necessary for our nervous systems to work properly, says the US National Institute of Neurological Disorders and Stroke (NINDS).

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", says NINDS.

Sex also helps by releasing many chemicals from your brains during and after the act.

Sleep so that I can enjoy sweet dreams and escape reality...

 

[Leongsam]

I have 8 hours of sleep every night.

i sleep better after sex...

8 hours with pill ; 4-5 hours without

After having my sleep pattern interrupted by nearby construction I am now having trouble sleeping properly. Especially since there are now more noisy people living in these new structures :(

The only time I get to sleep 9+ hours is when I am traveling & staying in a nice quiet hotel.

Johnny Bro, do you know if there is any supplements that can aid or improve the production of myelin? Looks like the key is to improve this particular protein in the brain.

I have tried melatonin, 5-HTP & Valerian root. Used to take them when they were building next door. There would be construction noises from 7am to 10pm, 7 days a week:(


However my current problem is with the noisy environment coming from the new neighbours living in the new buildings. I sleep better during sundays because it's quieter or sleep better with the windows closed.

i sleep better after sex...

Most women cannot sleep after sex, but were asleep before and during sex. Exactly the opposite.

Prolactin is the culprit.

Human shd sleep in the day and work at night.

Why? Get more sex during the day than night. Often you hear men say she is fucking hot!
