When the weather is hot, I often feel chest tightness and can't breathe. It's better to squat. What is wrong with me?

Your condition may be water and electrolyte disorder and low blood pressure caused by hot weather and excessive sweating. It is suggested to pay attention to the summer vacation, replenish fresh salt water in time and eat more fresh vegetables and fruits, which may gradually ease. Otherwise, if the symptoms persist, you need to go to the hospital to further improve the examination, make a clear diagnosis, and then targeted treatment.
