The benefits of sleep for BrainThe experts from the long time has difficulty to determining benefits of sleep. When asked about the benefits of sleep, then the experts will not know the answer. They only know the consequences if we are deprived of sleep. That's because so far, all the research in the field of sleep can not be directly examined the benefits of sleep. The only way is to examine the effect on a person if his reduced.
When deprived of sleep or suffering from sleeping sickness, a person experiences a decrease in brain functions. In addition, hormonal changes occur that will eventually interfere with organ functions to result in various diseases.
Experts have pointed to a decrease in endurance, increased blood pressure, decreased cardiac function, metabolic disorders, to the most easily seen is a decline in the quality of the skin.
In a further development, some diseases are suspected neurological impairment also exacerbated by lack of sleep or sleeping sickness. Call it Alzheimer's, dementia, or Parkinson 's disease.
The journal Science published a study that may shed some light on the benefits of sleep directly. This study states that sleep serves as a detox from residual materials unused brain.
Our body has a system to dispose of the remains of the burning of the body unused. The system has had this function. However, the brain has no lymphatic system. The brain has its own system. Blood brain barrier, for example, it serves as a kind of filter materials anything that gets in or out of the brain.
Experts say a system in the brain called glymphatic system, which is taken from the name of glial cells and the lymphatic system. Glial cells have also been known to play a role in the process of disposal of unused substances.
Glymphatic system is known as beta amyloid throw system, a metabolite that is trusted by the experts play a role in the development of Alzheimer's disease.
Go to sleep for Detoks
In theory, during wakefulness, the brain need to work hard as arson. This combustion produces unused junk. Garbage must be disposed of so as not to accumulate and poison the brain. Well, sleeping brain acts to detoxify from these toxic substances.
The experts want to see how the exhaust system works. For that they inject dye in rat cerebrospinal fluid. First with green dye, and these mice were stimulated to fall asleep. After sleeping for half an hour, these mice were injected with red dye.
By comparing the flow of cerebrospinal fluid color, experts can determine how to move fluid in the brain. It was found that the gap between the current cell is just 5 percent compared to waking during sleep. Thus concluded that, during sleep, the brain fluid flowing more profusely.
Compared with brain volume, inter -cell gap is 13-15 percent while awake. As for sleep, this gap widened 22-24 percent of brain volume. Unfortunately, researchers have yet to figure out how this gap could widen. Possibly because the cells that constrict during sleep.
Diseases of neuro-degenerative
Alzheimer 's disease and some diseases caused by other neurological impairment thought to be caused by lack of sleep and the buildup of waste products in the brain. Either because of the production of harmful metabolites or due to excessive exhaust system failure such substances, but the lack of sleep itself is almost certain to lose nerve functions.
All these factors will obviously damage the nerve neurons that eventually lead to dementia or senility.
Of course like other groundbreaking research, this study raises more questions. Hopefully future studies more enlightening about the relationship and disease -bed neuro-degenerative diseases.
