The Social Consequences of Sleep Deprivation
Sleep deprivation significantly impacts social behavior by making individuals asocial and prone to withdrawal from social interactions. Research shows that sleep-deprived individuals appear more socially repulsive to others, decreasing their attractiveness as potential friends or acquaintances. This reaction contributes to a cycle of increased loneliness among both the sleep-deprived and those interacting with them, further isolating the affected person. The implications extend even to civic engagement, as sleep-deprived people are less likely to participate in voting, highlighting the critical role of adequate sleep in functioning societies.
