The Human Body - What Causes People To Sweat When They Eat Spicy Foods?
What causes people to sweat when they eat spicy foods?
The chemical capsaicin, a component of spicy foods, is what causes sweating. It does this by stimulating nerve endings in the mouth and tongue that, normally, only respond to a rise in body temperature. As a result, the brain receives a false signal that body temperature has risen. This initiates the chain of physiological events that leads to the sweating of the face.
