Exercise and Fatigue: The Surprising Connection

You may have heard that exercise is good for reducing fatigue and increasing energy levels, but did you know that the relationship between exercise and fatigue is actually more complex than that? In fact, while exercise can have positive effects on energy levels, it can also sometimes cause fatigue, particularly if not done correctly or if done to excess. In this article, we’ll explore the surprising connection between exercise and fatigue, and what you can do to ensure that your exercise routine is working for you, not against you.

What Causes Fatigue?

Fatigue is a common issue that affects many people, and it can be caused by a variety of factors, including poor sleep, stress, illness, and more. When it comes to exercise, fatigue can be caused by overtraining, insufficient recovery, or a mismatch between the type of exercise and your fitness level.

How Does Exercise Affect Fatigue?

Exercise can affect fatigue in several ways. First, when done correctly and in moderation, exercise can help to increase energy levels by improving circulation, oxygenation, and the release of endorphins. However, if you push yourself too hard or exercise too much, you can actually increase fatigue, as your body struggles to keep up with the demands you’re putting on it.

Additionally, if you’re not getting enough recovery time between workouts, or if you’re not fueling your body properly, you may also experience increased fatigue as a result.

The Importance of Finding the Right Balance

The key to reducing fatigue through exercise is finding the right balance between intensity, frequency, and recovery. This means that you need to be mindful of how much you’re exercising, how often you’re exercising, and how you’re fueling and recovering your body.

Strategies for Reducing Fatigue Through Exercise

If you’re experiencing fatigue, there are several strategies you can use to help reduce it through exercise:

  1. Start with low-impact exercise: If you’re new to exercise or if you’re dealing with fatigue, start with low-impact exercise, such as walking, yoga, or swimming. This will help you to build up your fitness level gradually and avoid overexertion.
  2. Incorporate rest and recovery time: Make sure to give your body enough time to recover between workouts, and don’t be afraid to take a day off if you need it.
  3. Fuel your body properly: Make sure you’re fueling your body with the right nutrients before, during, and after exercise to help you perform at your best and recover quickly.
  4. Gradually increase intensity and frequency: Once you’ve built up a base level of fitness, you can gradually increase the intensity and frequency of your exercise, but be careful not to push yourself too hard too quickly.
  5. Find the right type of exercise: Finally, make sure you’re doing the type of exercise that’s right for you. If you’re feeling fatigued, avoid high-impact exercise, and instead focus on low-impact activities that will help you to conserve energy.


Exercise and fatigue may seem like an unlikely pairing, but in reality, the relationship between these two factors is much more complex than we often realize. By understanding the factors that contribute to fatigue, and taking a balanced approach to exercise, you can help to reduce fatigue and increase your energy levels. So, whether you’re new to exercise or a seasoned fitness enthusiast, take the time to find the right balance, and you’ll be well on your way to feeling better, stronger, and more energized.
