Loss of brain cells
According to one study that was carried out on rats, constant sleep deprivation led to the loss of brain cells over time. Chronic sleep deprivation can have the same impact on humans.
Accumulation of toxins
In 2012, researchers at the University of Rochester Medical Center found that while you sleep, your cerebrospinal is flushed, which is an energy-intensive process that can’t be done while awake. This process removes waste and toxins that play a role in brain disorders.
More prone to anxiety and depression
