Warning signs to stop going to the gym

When you exercise, blood flow to the brain increases to ensure it receives enough oxygen when the body is exercising at a high intensity. But this also means that the amount of _CO2 the brain needs to remove will increase. 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 symptoms that you are overdoing your physical activity and it is time to adjust. 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 several days and may be constant or intermittent.

Because everyone’s body is different, the intensity of exercise that triggers headaches 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 the head will make the head easily get hot. Because the head's ability to cool down by sweating is not as good as the rest of the body, the blood vessels will dilate to increase blood circulation. The blood will absorb some of that heat. Too much dilation of the blood vessels will cause headaches.

When you find yourself having a headache due to strenuous exercise, you need to stop exercising and rest. When resting, 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 about 3 hours for the headache to go away. Exercisers also need to pay attention to the intensity of exercise to avoid recurring pain, according to The Conversation .
