Never less sleep ? What do you feel ? Headache, trouble concentrating, memory impairment , and all feels slow. But why ? Researchers can find the answer.
The benefits of sleep
Experts from the difficulty of determining the benefits from a long sleep . When asked about the benefits of sleep , so experts do not know the answer. Only they 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 its small .
When deprived of sleep or suffering from sleeping sickness , the person experiences a decline in brain function. In addition , hormonal changes that eventually interfere with the functions of organs to give rise to various diseases occur .
Experts have noted decreased resistance , increased blood pressure , decreased cardiac function , metabolic disorders , and the easiest to see is a decrease in the quality of the skin.
In another 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 .
glymphatic system
The journal Science published a study that may shed some light on the benefits of sleep directly . This study affirms that sleep serves as a detoxification from waste materials unused brain .
Our body has a system to dispose of the remains of burning the body unused. The system has this feature. However, the brain has no lymphatic system. The brain has its own system. Blood-brain barrier , for example, serves as a kind of filter materials anything into or out of the brain.
Experts say that 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 removing unused substances.
System Glymphatic system known as beta amyloid shot , a metabolite that is trusted by the experts play a role in the development of Alzheimer's disease .
Go to bed to waste the toxic
In theory , during wakefulness , the brain has to work hard as arson. This combustion produces trash unused. Trash must be removed so it does not accumulate and poison the brain. Well, sleeping brain acts to detoxify these toxic substances.
Experts want to see how the exhaust system works. For injecting dye into the cerebrospinal fluid of rats . First with green dye , and these mice were stimulated to sleep. After sleeping for half an hour , these mice were injected with red dye .
When comparing the flow of cerebrospinal fluid color, the experts can determine how to move fluid in the brain . It was found that the gap between the current cell is only 5 percent compared with waking during sleep. It came to the conclusion that , during sleep, the brain fluid flows more freely.
Compared to brain volume , the gap between cells to 13-15 percent when awake. As for sleep , this gap widened 22 to 24 percent of brain volume. Unfortunately , researchers have yet to figure out how this gap could be extended . Possibly because the cells that contract during sleep.
Neurodegenerative diseases
Alzheimer 's disease and some other neurological diseases caused by deterioration thought to be caused by lack of sleep and the accumulation of waste products in the brain. Whether the production of harmful metabolites or system failure excessive exhaust those substances, but the lack of sleep itself is almost certainly lose nerve function.
These factors obviously damage nerve neurons that eventually lead to dementia or senile.
Of course , like other innovative research, this study raises more questions . Hopefully future most illuminating studies of the relationship and neuro - degenerative diseases beds disease.
