Does Running A Fever Burn Calories

As an avid runner and someone who has experienced my fair share of fevers, I’ve often wondered if running a fever actually burns calories. It’s a question that has intrigued me for quite some time, so I decided to do some research and dive deeper into this topic.

Understanding Fever

Before we can explore whether running a fever burns calories, it’s important to understand what a fever actually is. A fever is a temporary increase in body temperature, often as a result of an infection or illness. It is the body’s natural response to fight off and kill harmful pathogens.

When we have a fever, our body’s metabolic rate increases. This means that our body is working harder to fight off the infection, which may lead to an increase in energy expenditure. This begs the question: does the increased metabolic rate during a fever translate into burning more calories?

The Impact of Fever on Metabolism

While it’s true that a fever can increase metabolic rate, the extent to which it actually burns calories is not well-established. According to a study published in the American Journal of Clinical Nutrition, the increase in energy expenditure during a fever is relatively small, ranging from 7% to 13% above resting metabolic rate.

For example, if your resting metabolic rate is 1500 calories per day, running a fever might only increase your energy expenditure by around 100 to 200 calories. However, it’s worth noting that the increase in calories burned may vary from person to person and depend on factors such as the severity of the fever and individual metabolic differences.

The Importance of Rest

As tempting as it may be to hit the pavement and go for a run when you have a fever, it’s crucial to prioritize rest and allow your body to heal. Running or engaging in vigorous exercise can further stress your body, potentially prolonging your illness or worsening your symptoms.

When you’re running a fever, your body needs all the energy it can get to fight off the infection. By resting and conserving energy, you allow your immune system to work more efficiently, which can lead to a faster recovery.

Final Thoughts

While running a fever may slightly increase your metabolic rate and potentially burn a few extra calories, it’s important to remember that the primary focus should be on rest and recovery. Pushing your body too hard during a fever can do more harm than good.

Ultimately, the most effective way to burn calories and maintain a healthy lifestyle is through regular exercise and a balanced diet. So, if you’re feeling under the weather, embrace the opportunity to rest and take care of yourself. Your body will thank you in the long run!
