1, the exerciser lacks strenuous exercise. Usually there will be dizziness or headache, and there will be symptoms such as pallor, asthma, nausea, vomiting and muscle spasm.

Sometimes signing up for strenuous fitness exercise too early after illness, signing up for fitness exercise after fatigue or signing up for fitness exercise or competition under the condition of insufficient sleep will cause a series of diseases such as dizziness and headache. It should be clearly pointed out that people who didn't feel dizzy and tired before exercise now have such symptoms, accompanied by poor appetite, poor sleep, chest tightness, shortness of breath, sweating easily, high blood pressure and low physical fitness test scores. This should arouse vigilance.
