I feel dizzy after strenuous exercise, and my heart beats faster when I squat there. As soon as I stand up, my heart beats faster, and then I feel sick and faint. This is normal in theory, because the amount of exercise is too large and the exercise is too intense, so I can reduce the amount of exercise appropriately. [What is said here is that don't sit down and rest immediately after exercise, but walk slowly 10 minutes to relax] There is also: exercise is best not to be too intense or excessive, which is very harmful to the body! Exercise should be carried out according to everyone's different physical conditions!

But the landlord said that my head swelled very badly the next day, and I don't know. Generally speaking, a good sleep can be ensured after exercise. It should be refreshed the next day, so it can be said in theory!

I dare not jump to conclusions about the landlord as upstairs said. If the landlord feels that there is something wrong with his health, he'd better see a doctor. After all, doctors are authoritative!
