1. People who lack exercise engage in strenuous exercise. Usually there will be dizziness or headache, and there will be symptoms such as pallor, asthma, nausea, vomiting and muscle spasm. This is a reaction that the functional level of the body's respiratory organs cannot adapt to strenuous exercise. Poor breathing rhythm will lead to insufficient oxygen in the body and dizziness. Sometimes taking part in strenuous exercise too early after illness, taking part in exercise after fatigue or taking part in sports or competitions under the condition of insufficient sleep will cause a series of symptoms such as dizziness and headache. It should be pointed out that people who used to have no dizziness and fatigue during exercise now have these symptoms, accompanied by loss of appetite, poor sleep, shortness of breath, sweating, elevated blood pressure and decreased sports performance, so they should be vigilant.

2. The performance of insufficient calories in the body. Symptoms such as dizziness and dizziness appear after a period of exercise or near the end of exercise, especially when the outside temperature is too high or too cold, which may be related to insufficient heat in the body and decreased blood sugar content. Therefore, taking part in long-term exercise in a hungry state is prone to dizziness, fatigue and sweating.

3. Caused by some diseases. People with chronic rhinitis, sinusitis, inner ear diseases, anemia and high blood pressure may feel dizzy or headache during exercise. Among teenagers, especially female teenagers, symptoms such as dizziness, pallor and palpitation appear during exercise, which are often related to low hemoglobin. For symptoms such as dizziness caused by such reasons, we should actively treat the primary disease and fundamentally eliminate the cause. As can be seen from the reasons mentioned above, these common symptoms during exercise can be prevented. Prevention principles and treatment methods mainly include:

(1) Strengthen comprehensive physical exercise. Many examples show that many people's dizziness and other symptoms are often related to physical weakness and lack of overall physical exercise. Therefore, strengthening the overall exercise of the body is an important factor in prevention.

(2) Prepare activities and organize sports. Adequate warm-up activities can avoid dizziness and headache caused by strenuous exercise. After doing exercise, you can avoid this symptom caused by an emergency stop.

(3) ensure that the body has enough heat supply. Before long-term exercise or competition, you should take enough sugary equipment to avoid dizziness due to insufficient calories.

(4) timely discover and treat excessive fatigue.
