It is cool today. After riding a bike for half an hour, I feel dizzy. I feel much better after squatting. My arm is cold, but my hair is wet with sweat.

Disease analysis: You don't rule out the possibility of anemia. It is recommended to do routine blood tests to make sure that you usually eat foods rich in high protein, vitamin B and vitamin C and diets rich in iron. Such as apples, jujubes, lychees and bananas. You should also eat more black fungus, mushrooms, black beans, sesame seeds and other foods, which is conducive to nourishing blood.

Suggestion: Severe anemia can lead to dizziness, headache, fatigue, insomnia, dreaminess, dizziness, black eyes and other symptoms. 90- 1 10g/l is mild anemia, 60-90 is moderate anemia, and moderate anemia requires medical treatment.
