After exercising, the body experiences an increase in temperature due to the processes of cellular respiration. During aerobic exercise, oxygen is utilized to oxidize glucose, producing energy, water, and carbon dioxide, which generates heat as a byproduct. In anaerobic conditions, when oxygen is scarce, the body resorts to anaerobic respiration, leading to lactic acid production and further heat generation. This thermogenic effect is similar to how a car engine generates heat and requires cooling, highlighting the exothermic nature of these biochemical reactions.
