Never sleep deprivation? What were you feeling? Headaches, hard to concentrate, memory decrease, and all of it feels sluggish. But why? Researchers may have found the answer.
The benefits of sleep
Experts have long been trouble determining the benefits of sleep. If asked about the benefits of sleep, then the experts will answer don't know. They only knew the consequences if we lack sleep. That's because during this time, all research in the field of sleep is unable to directly examine the benefits of sleep. The only way of researching is to look at its effect on someone if sleep was reduced.
When lack of sleep or suffer from sleeping sickness, someone experiencing loss of brain functions. In addition, hormonal changes occur that will eventually disrupt the functions of the organs of the body and result in various diseases.
Experts have pointed to a decrease of body endurance, increased blood pressure, decreased cardiac function, metabolic disorders, up to the most easily visible is a decrease in the quality of the skin.
In a further development, several diseases decreased nerve function also suspected was exacerbated by lack of sleep or sleeping sickness. You name it, dementia, alzheimer's or parkinson's disease.
System glymphatic
The journal Science publishes a study that may give you a little enlightenment about the benefits of sleep directly. The study mentions that sleep serves as detox from materials remaining unused brain.
Our body has a system for disposing of the remains of the burning of the body unused. The system has had this functionality. 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 just about anything can get in or out of the brain.
Experts say a system in the brain called the glymphatic system, which is taken from the name of glial cells and lymphatic system. Glial cells have also been known to play a role in the process of disposal of unused substances.
This is known as the glymphatic system is the system that discards amyloid beta, a metabolite which is believed by the experts involved in the development of Alzheimer's disease.
Sleep to dispose of toxins
In theory, as long as the brain awake, working hard as if in need of combustion. This resulted in a combustion residual unused junk. Garbage-garbage must be disposed of so that it cannot accumulate and poison the brain. Well, sleep role to detoxify the brain from toxic substances.
Experts want to see how work this exhaust system. For that they inject the dye substance in the brain fluid of rats. First with green dye, and this stimulated rats to fall asleep. After sleeping for half an hour, the rats were injected with a dye that is red again.
By comparing brain this colored liquid flow, experts can determine how fluids move in the brain. Found that the gap between the cells while awake is merely 5 percent than when sleeping. Thus it was concluded that, while sleeping, brain fluid to flow more copiously.
Compared with the volume of the brain, the gap between the cells while awake is 13-15 percent. As for while sleeping, this gap widened 22-24 percent of the volume of the brain. Unfortunately, researchers have yet to figure out how this gap could widen. Possibly because the cells shrinks while sleeping.
Diseases neuro-degenerative
Alzheimer's disease and some diseases due to other suspected nerve function caused by lack of sleep as well as buildup of residual substances in the brain. Either because production of metabolites of metabolites of excessive harm-or because of a breakdown in the system of disposal of such substances, but the lack of sleep itself is certainly going to lose nerve functions.
All these factors will certainly damage the neurons nerves that eventually led to dementia or senility.
Certainly like other groundbreaking studies, this study raises more questions. Hopefully more studies giving enlightenment about the relationship of sleep and disease-disease of the neuro-degenerative diseases.
