Question

Why do we get hot when we exercise?

Answer 1

It’s your body’s way of regulating your core temperature, preventing you from overheating. Your muscles heat up as they expend energy during exertion. When this happens, your skin begins to sweat, causing your body to cool down. The spike in your body heat also alerts your brain to ensure your body remains at the normal core temperature of 98.6 degrees Fahrenheit (or 37 degrees Celsius).

Answer 2

While exercising the body begins to warm up. When the body begins to warm up our muscles convert stored energy into heat energy, making our bodies become warmer. As the body heats up further the brains thermostat ensures that you remain close to the normal core temperature.
