What causes headaches after strenuous exercise?

Nowadays, people pay more attention to health preservation, so in their spare time, more and more people join the sports army; some people want to make themselves thinner, so they also often participate in some sports to lose weight. However, some people find that as long as the amount of exercise increases, they will experience headaches. So, what’s going on?

1. People who lack exercise engage in strenuous exercise. Usually, there are dizziness or headache, as well as pale face, shortness of breath, nausea, vomiting, muscle cramps and other symptoms. This is the response required when the functional level of the body's respiratory organs cannot adapt to intense exercise. Poor breathing rhythm can lead to insufficient oxygen in the body and cause dizziness. Sometimes participating in strenuous exercise too early after an illness, exercising after being tired, or participating in sports or competitions without enough sleep can cause a series of symptoms such as dizziness, vertigo, and headache. It should be pointed out that people who did not experience symptoms such as dizziness and weakness when exercising, but now experience these symptoms, accompanied by loss of appetite, poor sleep, shortness of breath, sweating, increased blood pressure and decreased athletic performance, should be alert.

2. Signs of insufficient calories in the body. When symptoms such as dizziness and lightheadedness begin after a period of exercise or near the end of exercise, especially when these symptoms occur when the outside temperature is too high or too cold, the cause may be related to insufficient heat in the body and low blood sugar levels. This is why it is easy to experience dizziness, weakness, sweating, etc. if you participate in long-term exercise when you are hungry.

3. Caused by some diseases. People with chronic rhinitis, sinusitis, inner ear diseases, anemia, and hypertension may experience dizziness, lightheadedness, or headaches during exercise. Among adolescents, especially female adolescents, when they experience symptoms such as dizziness, pale face, and palpitations during exercise, it is often related to low hemoglobin levels.

If you get a headache when you are doing a lot of exercise, you should first consider whether you are lacking exercise or exercising while hungry. These situations can be alleviated by reducing exercise and replenishing energy for the body in time. If these two reasons are ruled out, you should see a doctor in time, because this may be a sign of some disease in your body.
