Sleep Benefits For The Brain

Do not underestimate the benefits of sleep. Scientists believe they have found a new reason, because it helps replace the activity of brain cells.

Sleep increases the production of coating cells material called the myelin that protects the brain circuitry. Although the discovery has been only demonstrated in mice, but can reveal the role of sleep in brain development and improvement and the MS disease.

The study found that the rate of production of myelin making cells, oligodendrocytes, doubled when mice sleep. This increase will be very high when one enters the stage of dreaming or REM sleep (rapid eye movement) and driven by genes. Conversely, genes that play a role in cell death and response to stress is activated when rats are forced to awake.

The reason why humans need sleep has made scientists wonder for hundreds of years. It is clear that we need sleep to rest our mind and in order to function properly, but the biological processes that occur during sleep were only discovered recently.
