Why do you feel chest tightness when the weather is hot?

There is no absolute relationship between air pressure and season.

Breathing difficulties during running are not necessarily due to air pressure. In winter, the air temperature is low and the temperature is low. Gas with lower temperature enters the lungs, which will cause the feeling of difficulty in breathing. Even in summer, if you suddenly stand under the air conditioner and the air conditioner blows on your face, you will find it difficult to breathe.

Breathless heat is the result of severe temperature regulation of the body. Increased perspiration and increased water loss during breathing are all means for the human body to adjust problems, and these all require energy and oxygen consumption, so we feel that the air we breathe is not enough and we feel breathless.

Therefore, dyspnea can't be linked to air pressure, and the specific problems are treated specifically. Even on the same day, you will gasp badly after strenuous exercise, which is the same as being breathless with heat. Your body needs a lot of oxygen, so you will breathe more and you will feel out of breath.
