California (US): Humans help one another; it is one of the pillars of civilised society. However, a new study conducted by scientists at the University of California, Berkeley, reveals that a lack of sleep impairs this fundamental human trait, with real-world consequences.
Sleep deprivation has been linked to an increased risk of cardiovascular disease, depression, diabetes, hypertension, and overall mortality. These new findings, however, show that a lack of sleep also impairs our basic social conscience, causing us to withdraw our desire and willingness to help others.
