Both the exercise itself and the air temperature and humidity can increase your core body temperature. To help cool itself, your body sends more blood to circulate through your skin. This leaves less blood for your muscles, which in turn increases your heart rate. … That pushes your body temperature even higher.
How much does body temperature rise during exercise?
Given that mechanical efficiency varies from 20 to 25%, most of the metabolic energy converted to produce movement is released as heat. For example, exercise performed at 80 to 90% of maximal aerobic capacity (VO2 max) could increase core temperature by 1°C every 5 to 8 minutes if heat was not dissipated.
Will my temperature be higher after a workout?
While the body temperature may increase slightly, the body’s temperature typically returns to normal within 20 minutes after the exercise has been completed.

Is 99.3 a fever in adults?
A normal adult body temperature, when taken orally, can range from 97.6–99.6°F, though different sources may give slightly different figures. In adults, the following temperatures suggest that someone has a fever: at least 100.4°F (38°C) is a fever. above 103.1°F (39.5°C) is a high fever.
