Can a simple laugh physically alter your body's pain tolerance?
In short: Laughter is often dismissed as a mere reaction to humor, but it may have deeper physiological functions. This video explores whether the act of laughing can actually raise your pain threshold, using human experiments to test the biological mechanics of this complex behavior.
Anthropologist Professor Robin Dunbar conducted experiments to investigate the relationship between laughter and physical sensation. By intentionally inducing pain in subjects, he sought to determine if a preceding bout of laughter could increase the threshold at which a person feels discomfort.
The study situates laughter as a pivotal evolutionary behavior. While it is often described as the 'enemy of breathing,' modern science is beginning to uncover how this obscure action has served our species. The research aims to move beyond the 'why' of jokes to understand the underlying biological and evolutionary significance of the laugh reflex.
