There are so many people on the subway that I feel chest tightness and retching

It is quite common in our daily life to feel chest tightness and dry retching in crowded subways. There are many causes for this. For example, there are many people in subways, so the air is relatively polluted and there is no fresh air entering. People often feel shortness of breath and dizziness, which may induce chest tightness and dry retching. Of course, it may also be related to some cardiopulmonary diseases. For such patients, there are many people in subways and the space is relatively small, which can easily induce such symptoms.

The subway is crowded and I feel chest tightness and retching

Chest tightness and shortness of breath are common subjective feelings in the human body, and are more common in middle-aged and elderly people. Those with mild symptoms may feel fine, but those with severe symptoms may feel difficulty breathing. Patients with chest tightness and shortness of breath often feel that their chests are particularly heavy, as if a stone is pressing on their chests. Severe cases can cause difficulty breathing. Chest tightness and shortness of breath are sometimes functional manifestations of human organs, and sometimes they may be one of the earliest symptoms of disease in the human body.

Chest tightness and shortness of breath are sometimes functional manifestations of human organs, and sometimes they may be one of the earliest symptoms of disease in the human body. Generally speaking, chest tightness and shortness of breath can be divided into the following two types:

1. Functional chest tightness

That is, symptoms of chest tightness and shortness of breath occurring without any organic disease. Staying in a room with closed doors and windows and poor air circulation for a long time, or encountering some unpleasant things, or even having quarrels or disputes with others, or being in a climate with low air pressure, will often cause feelings of chest tightness, shortness of breath, and fatigue. After a short rest, opening windows for ventilation or going outside to breathe fresh air, relaxing your mind and regulating your emotions, you will soon return to normal.

Experts point out that due to the influence of anxiety, tension, emotional excitement, mental trauma and other factors, the central excitation and inhibition processes are disturbed, and the cardiovascular system regulated by the autonomic nervous system also becomes disordered, causing a series of symptoms of excessive sympathetic nerve tension.

2. Pathological chest tightness

That is, symptoms of chest tightness and shortness of breath caused by organic diseases. Experts point out that chest tightness can not only be physiological, but can also be caused by diseases in certain organs in the body, that is, pathological chest tightness. Common causes of pathological chest tightness include respiratory obstruction, lung disease, heart disease, diaphragm disease, fluid metabolism and acid-base balance disorders, etc.
