A study has suggested that when we sleep, our brains work to clear away the entire junk that piles up in them while we are awake. According to the researchers, this suggestion might help in the treatment of Alzheimer’s disease and other disorders.
Sleep Might Slow Brain Damage
Although the effect of sleep on brain cleaning was detected in mice, scientists say that there is no reason why the results cannot be extrapolated to humans. If brain cleaning also occurs in people, it implies that ‘sleep would perhaps be even more important in slowing the progression of further damage’, said Dr. Clete Kushida, medical director of the Stanford Sleep Medicine Center.
During the course of the study, the research team at the University of Rochester Medical Center observed that when the mice slept, the brain cells shrank which widened the inter cell spaces, thereby providing ample space for waste to be flushed out.
