The summary video features Matthew Walker, a professor of neuroscience and psychology at the University of California Berkeley, who discusses the effects of sleep deprivation on the body and brain.
Lack of sleep can prevent the brain from making new memories, increase the risk of developing Alzheimer’s disease, and age the reproductive system by almost a decade.
It can also weaken the immune system, increasing the risk of developing cancer, and impact the cardiovascular system, raising the risk of heart attacks and strokes.
After 16 hours of being awake, mental and physiological deterioration begins, and after 19-20 hours, mental capacity is impaired to the extent of someone who is legally drunk behind the wheel of a car.
Walker emphasizes the importance of getting sufficient sleep to repair the damage of wakefulness.
