The average human body at rest radiates about the same amount of heat as a 100-watt light bulb. Which is fine when the ambient temperature is at or below the body temperature of 37°C (98.6°F). When our surroundings exceed the normal body temperature, the only way to keep from overheating is by evaporative cooling—a.k.a. sweating.
