Sleep deprivation linked to loneliness | Matthew Walker
Lack of sleep carries many risks, one of which has serious social consequences. Chiefly, sleep deprivation triggers the onset of a "loneliness phenotype" by inducing critical changes within the brain that alter behavior and emotions, disturb metabolic processes, and influence the expression of immune-related genes. The end result is that people who are sleep-deprived avoid social interaction. Their standoffishness is recognized by other people who, in turn, shun the sleep-deprived people as if they were ill, creating a vicious cycle of loneliness. In this clip, Dr. Matthew Walker describes how sleep deprivation promotes a kind of "viral" loneliness.
