Why Does It Hurt To Breathe After Running

After a long run, you may have experienced that sharp pain in your chest, making it difficult to take a deep breath. It can be quite alarming and even scary, especially if you’re not familiar with the sensation. As a runner myself, I’ve encountered this issue numerous times, and I know how uncomfortable it can be. In this article, we’ll delve into why it hurts to breathe after running and what you can do to alleviate this discomfort.

Understanding the Cause

The most common reason for chest pain while breathing after running is exercise-induced asthma. Exercise-induced asthma is a condition in which the airways in our lungs narrow during physical exertion. This causes shortness of breath, chest tightness, and wheezing. If you’ve been diagnosed with asthma, it’s crucial to manage your symptoms and have an inhaler with you during your runs.

Another reason for chest pain while breathing after running is a phenomenon known as “stitch.” A stitch is a cramp-like pain that typically occurs on one side of the abdomen, just below the ribs. Although the exact cause of a stitch is still unknown, some theories suggest that it may be due to diaphragm muscle spasms or reduced blood flow to the diaphragm during exercise. To prevent stitches, make sure to avoid eating a large meal before running and practice deeper breathing techniques during your workout.

Additionally, inadequate warm-up or cooldown routines can contribute to chest pain after running. When we abruptly start or stop our runs without properly preparing or cooling down our bodies, the muscles surrounding our lungs may tighten, causing discomfort when breathing deeply. Taking the time to warm up and cool down properly can help prevent this.

Dealing with the Discomfort

If you experience chest pain while breathing after running, there are several steps you can take to alleviate the discomfort:

  1. Slow down: If you’re running at an intense pace, try dialing it back a bit. Slowing down can help reduce the strain on your respiratory system, allowing you to breathe more comfortably.
  2. Focus on your breathing: Pay attention to your breathing patterns during running. Try to take slow, deep breaths in through your nose and out through your mouth. This can help relax your airways and reduce the likelihood of experiencing chest pain.
  3. Warm up and cool down properly: Before starting your run, engage in a dynamic warm-up routine to prepare your body for exercise. Similarly, after your run, perform a cooldown routine to gradually bring your heart rate back down. This can help prevent muscle tightness and chest pain.
  4. Stay hydrated: Adequate hydration is essential for optimal lung function. Make sure to drink enough water throughout the day, especially before and after your runs.
  5. Consider your environment: Environmental factors, such as pollution or cold weather, can exacerbate chest pain while breathing. If possible, try to run in areas with clean air and consider wearing a scarf or face mask in cold weather.


Experiencing chest pain while breathing after running can be distressing, but it’s essential to understand the potential causes and how to manage them. Remember to listen to your body and adjust your running routine accordingly. If the discomfort persists or worsens, it’s always wise to consult with a healthcare professional to rule out any underlying medical conditions. With the right precautions and strategies in place, you can continue enjoying the many benefits of running while minimizing discomfort and promoting your overall well-being.
