Why Does Exercise Increase My Body Temperature? |

Everyone has felt the discomfort of a heat stroke while working out in a hot room. If you don’t take precautions, you can suffer a heat stroke. Heat stroke is defined as a condition where the body’s temperature is elevated to over 104 degrees, causing the individual to experience severe dizziness, confusion, and impaired judgment. What is the cause of these symptoms? What can make a body overheat? To answer these questions, a scientist must first understand the physics of heat, and in particular the relationship between heat, temperature, and the rate at which the body produces heat.

When you exercise you get more blood pumping through your muscles, and that means your heart beats faster and you get more oxygen to your muscles. That extra oxygen can raise your body temperature, but why does exercise warm up your body? There are two main factors that cause your body temperature to rise. One is called heat production. This is the amount of heat that you generate when you do aerobic exercise like running, cycling or swimming. The other is called heat transfer. This is the amount of heat that your body transfers from the air to your skin when you’re exercising. You can see this increase in heat production and heat transfer on a treadmill or in a pool.

As you repeat the same exercise on a daily basis, your body will continue to get used to your routine. However, the body’s response to exercise is not the same for each individual.. Read more about why does exercise increase body temperature and let us know what you think.

When I work out, I notice that my body temperature rises and I start sweating profusely. Is this typical, and can I do anything to keep my body from overheating during exercise?

Our Quick Response

Yes, it’s natural for you to become hot while you exercise. It’s your body’s method of keeping you from overheating by controlling your core temperature. During exercise, your muscles heat up as they waste energy. Your skin starts to sweat as a result, causing your body to cool down. Your brain is also alerted by the increase in body heat to ensure that your body maintains its normal core temperature of 98.6 degrees Fahrenheit (or 37 degrees Celsius).

Our Long Response 

Your muscles convert stored energy into heat energy as you exercise, causing your body to warm up. Your brain’s thermostat, the hypothalamus, ensures that you stay close to your usual core temperature of 98.6 degrees Fahrenheit (37 degrees Celsius) when your body warms up. Your skin will begin to sweat to release heat and cool your body down in order to maintain a normal temperature range.

However, when your body cools down, you won’t notice any changes right away. According to Dr. Ollie Jay, founder of the University of Ottawa’s Thermal Ergonomics Laboratory, our bodies need 30 to 45 minutes of activity to get rid of the high temperature.

It will take almost an hour for your body to cool down enough to avoid overheating. This is also why, even after you’ve completed your exercise, you’ll typically continue to sweat for a few minutes longer.

The pace at which you cool down after an activity is also determined by your body size. When compared to bodies with lower surface area to mass ratios, bodies with greater surface area to mass ratios are more likely to cool down faster, making them seem colder.

It’s all good, though—regular exercise may increase your body temperature, but it offers a slew of other advantages. Regular exercise increases blood circulation and reduces vital numbers such as blood pressure, cholesterol, and the risk of most illnesses. It may also assist you in reaching your desired weight, depending on your health objectives and how you exercise. Do you know anything else? Daily exercise may also help your body relax, allowing you to sleep better.

Don’t worry if you start to feel hot and sweaty throughout your next exercise; your perspiration will ultimately cool you down. Just remember to drink water to avoid dehydration if this occurs!


According to legend, the ancient Greek athlete Milo of Croton had a condition called hyperthermia , which is the occurrence of an abnormally high body temperature while exercising.  This condition was supposedly caused by excess heat production in the body, which caused the body to overheat. In reality, I think the problem was caused by excessive sweating. Everyone sweats when they exercise, but the sweat from a hot body produces a higher concentration of heat than that of a cool body, so a sweaty body will become hotter than a dry body.  This is why we see the well-known Dr.  Irving Gill wearing a long-sleeved shirt when he walks around his office, and we see the sweaty athletes at the gym.
