Sleep helps eliminate toxins in the brain

Recent research by American scientists shows that sleep helps people eliminate harmful toxins in the brain after a stressful working day.

According to scientists, toxic waste can be removed from the brain when people sleep and the system to remove these toxins is also one of the basic reasons for human sleep, BBC reported.

During sleep, cells in the brain like glial cells function to make nerve cells shrink. This process will increase the size of the gaps in brain cells and allow more liquids to be removed to remove toxic scents. When conducting research in rat brains, scientists found that this process took 10 times more effectively while mice slept.

Scientists have previously demonstrated the role of sleep in restoring memory and learning ability. However, the research group at Rochester Medical Center said that the mechanism of cleaning up toxic substances in the brain is one of the main reasons for sleep.

"The brain's energy source is quite limited, so the brain can only choose to perform two different functions that are awakening and awareness, or sleepiness and cleansing of toxic substances in the brain , " said Dr. Maiken Nedergaard said.

Research has important implications for demonstrating the role of sleep in brain cell rehabilitation and may have other protective effects on the brain.

Some toxic proteins that are not cleaned can cause disorders in the brain. Alzheimer's or Parkinson's disease are characteristic diseases caused by damaged proteins that accumulate in the brain.
