There are roughly the following reasons for dizziness, lightheadedness or headache during exercise.

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 (blood pressure foods) and decreased athletic performance, should be alert.

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

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 (juvenile food), when they experience symptoms such as dizziness, pale face, and palpitations during exercise, it is often related to low hemoglobin.

The main principles of prevention and treatment methods are:

Strengthen comprehensive physical exercise. Many examples show that many people experience symptoms such as dizziness due to physical weakness and lack of overall physical exercise. Therefore, strengthening comprehensive physical exercise is an important factor in prevention.

Do warm-up and cool-down exercises. Sufficient warm-up can help avoid dizziness, headaches and other symptoms caused by intense exercise. If the cool-down exercise is done well, this symptom caused by sudden stopping can be avoided.

Ensure sufficient heat supply to the body. Before prolonged exercise or competition, you should take enough sugary foods to avoid symptoms such as dizziness and lightheadedness caused by lack of calories.
