Warning signs to stop going to the gym

When you exercise, blood flow to the brain increases to ensure that the brain receives enough oxygen when the body is exercising at high intensity. But this also means that the amount of _CO2 that the brain needs to remove increases. To cope with this, the blood vessels leading to the brain will dilate and can cause headaches, according to the news site The Conversation (Australia).

Headaches while exercising are a warning sign that you need to stop exercising and rest.

Therefore, headaches are one of the warning signs that you are overdoing your physical activity and need to make adjustments. Physical activities that can cause headaches are often jogging or lifting objects that are too heavy.

This type of headache is often described as a throbbing sensation on either side of the head, near the temples. Some people describe it as a migraine-like headache. The headache can last from a few minutes to a few days and may be constant or come in waves.

Because everyone’s body is different, the intensity of exercise that triggers a headache also varies. In addition, certain conditions can make exercise-induced headaches more likely. Exercising in hot weather is one example.

Sunlight shining on the top of your head can easily cause your head to get hot. Since the head’s ability to cool itself by sweating isn’t as good as the rest of your body, the blood vessels dilate to increase circulation. The blood absorbs some of that heat. Too much dilation of the blood vessels can cause headaches.

When you find yourself having a headache due to strenuous exercise, you need to stop exercising and rest. When you rest, your heart rate will decrease, your brain's need for oxygen will decrease, your body temperature will decrease, and the pain will also disappear after 1 or 2 hours. If your body is dehydrated, it will take more time to rebalance and the headache will go away after about 3 hours. Exercisers also need to pay attention to the intensity of exercise to avoid recurring pain, according to The Conversation .
