The weather is sultry, chest tightness and shortness of breath.

I started this situation when I was a teenager. Especially when the weather is sultry, sometimes I feel too bored to sleep. The gas in the trachea doesn't seem to sink into the stomach, does it?

Originally, I went to see a Chinese doctor, who said that I was deficient in qi and blood. I ate Bazhen Mu Yi Pills and Ejiao for a while, but a year later, I began to get sick again, and I never found the root cause.

The first year of military training began again, and I went to the school hospital to get oxygen. After three days in a row, it was a little better. It will not be completely cured until the end of military training. The doctor said I was too nervous.

I finally got an explanation from an experienced doctor not long ago. Everyone has a normal sinus arrhythmia, but maybe I like sports too much and my heart rate is slow. But my exercise is not very regular, so my heart rate fluctuates too much. Irregular heart rate will affect breathing.

The doctor's advice is to keep exercising regularly, which will change your color in the long run.

I hope I can help you.
