Son cleanses toxins from

While our body is at rest, our brain holds the hard work by removing toxins that are produced during our waking hours.

Accumulating, these compounds can lead to a number of diseases, including Alzheimer's disease and other neurological diseases.

Scientists from the University of Rochester Medical Center (URMC) came to the following conclusion: cleaning of the brain that occurs during sleep, so energy-intensive that if these "Dump" processes occur during wakefulness, just to prevent the thought processes of man. Because sleep is vital for a normal human being and a "clear" head.

Scientists give an example: a person can not simultaneously receive guests and deal with cleaning the house. Similarly, the brain, appear to be unable to "master", "clean" himself from the biochemical debris and simultaneously engage in the processing of incoming information.

"Our study suggests that the brain performs different functions depending on the state in which the person resides," - experts say. According to the authors, some incurable diseases are a consequence of chronic sleep deprivation, when the brain just does not have time to clean the toxic substances produced during the day's work.

Interestingly, the brain during sleep cells "compressed" by nearly 60%, to aid purification processes, thus extending channels for circulation of cerebrospinal fluid.
