If you get hot after a hard workout, you are not alone. And although an increase in temperature may seem obvious, it is essential to know why it is happening. Why do you get warm when you exercise?
Does exercise increase body temperature?
Yes, exercise increases body temperature. After a few minutes of cardio, you will feel the effects of exercise on your body temperature. Body temperature increases because heat is created when your muscles create energy. Usually, the muscle stores a small amount of energy inside, and when this is used, it must make extra energy to continue the activity.
One study found that runners had more heat around their legs than their arms during exercise. The extra energy needed to continue running was evident in total body temperature over the legs and thighs.
When you use the muscles during exercise, 80 percent of the total energy is converted into heat. This heat energy is distributed throughout the body and can cause the body temperature to increase.
Average body temperature during exercise
How high your body temperature rises depends on several factors, including:
- Type of activity
- Room temperature
When the body temperature rises, the body has mechanisms to keep the core temperature safe. These mechanisms include moving blood flow closer to the skin, breathing heavier, and sweating.
Your ability to regulate temperature during exercise also depends on countless factors, he adds, including:
- Aerobic fitness
- Individual acclimatization
- Hydration status
How long the body temperature stays elevated
The body temperature will return to normal shortly after exercise. The increase in temperature can persist for the next 15 to 20 minutes. It will take some time to cool your body back to a lower temperature.
High body temperature during exercise
Heatstroke can occur when you exercise in hot weather, and the cooling system must operate on overdrive. You need to pay attention to an average body temperature. Although it is customary to slightly increase body temperature during exercise, too much increase can be a red flag for a severe problem. Signs of heatstroke include:
- Shallow or fast breathing
- Fast or weak pulse
To stay cool and avoid an unsafe temperature rise during exercise, drink plenty of water throughout the day, including physical activity. It is also good to avoid the hottest times and move the training to morning or evening.
