Why Do I Get Headaches When Exercising?

Exercising is essential for maintaining a healthy lifestyle. It helps improve cardiovascular fitness, build strength, and reduce stress levels. However, some individuals experience headaches during or after exercise, which can be quite uncomfortable and concerning. In this article, we will explore the reasons behind why this happens and offer some potential solutions.

What Causes Exercise-Induced Headaches?

Exercise-induced headaches, also known as exertional headaches, can be triggered by various factors. Here are some common causes:

1. Dehydration

One of the primary reasons for exercise-induced headaches is dehydration. When we exercise, our bodies lose fluids through sweat, and if we don’t replenish those fluids adequately, we can become dehydrated. Dehydration can cause blood vessels in the brain to constrict, leading to headaches.

2. Poor Posture

Incorrect posture during exercise can put unnecessary strain on the neck and shoulders. This strain can result in tension headaches or even migraines, causing discomfort during or after workouts.

3. Hot and Humid Environments

Exercising in hot and humid environments can raise the body’s core temperature and increase blood flow to the skin for cooling. These changes can lead to dilated blood vessels in the head, triggering headaches.

4. Exertion and Physical Strain

Intense physical exertion can cause the blood vessels in the scalp, neck, and head to expand rapidly. This sudden expansion can result in exercise-induced headaches.

5. Reduced Oxygen Levels

During exercise, there is an increased demand for oxygen by the muscles. If the body cannot supply enough oxygen to meet this demand, it can lead to headaches.

Solutions to Exercise-Induced Headaches

If you frequently experience headaches during or after exercise, here are some tips to help alleviate the discomfort:

1. Stay Hydrated

It is crucial to drink plenty of water before, during, and after your workout to maintain proper hydration levels. This will help prevent dehydration-induced headaches.

2. Correct Your Posture

Ensure that you maintain proper posture and form while exercising, especially during weightlifting or activities that involve repetitive motions. This can help reduce the strain on your neck and shoulders, preventing tension headaches.

3. Control the Environment

If exercising in hot and humid conditions triggers headaches, try to exercise in a cool and well-ventilated environment. This will help regulate your body temperature and minimize the risk of blood vessel dilation in the head.

4. Gradually Increase Intensity

Avoid suddenly pushing yourself to the limits during workouts. Instead, gradually increase the intensity and duration of your exercise sessions. This will allow your body to adapt and reduce the likelihood of exertion-induced headaches.

5. Breathe Properly

Paying attention to your breathing pattern during exercise is essential. Practice deep, controlled breathing to ensure an adequate supply of oxygen to your muscles, reducing the chances of headaches.

6. Warm Up and Cool Down

Always warm up before starting your workout and cool down afterward. This helps prepare your body for physical activity and prevents sudden changes in blood flow that can trigger headaches.

7. Consider Medication

If exercise-induced headaches persist despite implementing these lifestyle changes, it may be helpful to consult with a healthcare professional. They can prescribe medication or provide alternative methods for managing the headaches.


1. Can exercise cause migraines?

Yes, intense physical exertion can trigger migraines in some individuals. It is essential to pay attention to your body’s response and modify your exercise routine accordingly if migraines occur frequently.

2. Should I stop exercising if I experience headaches?

If you experience headaches during exercise, it is generally safe to continue exercising. However, if the headaches are severe or accompanied by other concerning symptoms, it is advisable to consult a healthcare professional.

3. Can lack of sleep contribute to exercise-induced headaches?

Yes, lack of sleep can increase the risk of exercise-induced headaches. Getting adequate rest and prioritizing sleep can help reduce the likelihood of experiencing headaches during workouts.

4. Are there any specific exercises that can help prevent exercise-induced headaches?

Although there is no specific exercise that can prevent exercise-induced headaches, incorporating relaxation techniques such as yoga or meditation into your routine can help alleviate stress and tension, reducing the chances of headaches.

5. Can consuming caffeine help prevent exercise-induced headaches?

For some individuals, consuming caffeine before exercising can help prevent exercise-induced headaches. However, it is important to remember that caffeine affects individuals differently, and excessive consumption can have adverse effects.


Experiencing headaches during or after exercise can be frustrating, but identifying the underlying causes can help find effective solutions. Staying hydrated, maintaining proper posture, controlling the environment, and gradually increasing intensity are some ways to manage exercise-induced headaches. Remember to listen to your body and consult a healthcare professional if headaches persist or worsen.
