How body produce heat
WebNormal human metabolism produces heat at a basal metabolic rate of around 80 watts. [1] During a bicycle race, an elite cyclist can produce close to 400 watts of mechanical power over an hour and in short bursts over double that—1000 to 1100 watts; modern racing bicycles have greater than 95% mechanical efficiency. WebAt 30 o C, it is approximately 2.4 MJ/L. Sweating is a primary mechanism that our body uses to cool us; on a hot day, we sweat, and the sweat evaporates off our skin, cooling us. The energy to evaporate our sweat, the latent heat of vaporization, is provided by our bodies. This evaporation, in turn, cools our bodies.
