When the human body begins to overeat it attempts to maintain a constant temperature through several mechanisms including perspiration. Another mechanism with the same effect in blood volume expansion of the skins blood vessel conservation of body fluids and sauce a decrease in food digestion a decrease in urine production
is the activation of the parasympathetic nervous system. The parasympathetic nervous system stimulates the release of acetylcholine, which in turn leads to vasodilation of blood vessels in the skin, conserving body fluids and facilitating heat dissipation through sweating. Additionally, the parasympathetic nervous system promotes rest and relaxation, which can decrease food digestion and urine production. These mechanisms work together to help maintain a constant body temperature when overeating occurs.
