Stay up too much, chest tightness.

"I am 19 years old this year. I have smoked for about a year. I have smoked quite a lot recently, one pack a day. I often play games all night these two days, about two days. I feel stuffy in my chest, breathing heavily, and I need to breathe heavily to be comfortable. What is the reason? I have been staying at home recently, rarely going out, always sitting on the bed playing computer, feeling very stuffy in my chest and being pressed by something. "

These are all related to your playing games all night these days, overwork, smoking a lot, bad air in the room and excessive use of your brain.

I suggest you do outdoor aerobic exercise,

Smoke less and drink more water.

A balanced diet and a rhythmic life,

Adjust it for a few days,,,,

If it's still like this in a few days, I suggest you go to the hospital.
