What causes shortness of breath

Shortness of breath is a subjective feeling, or it can be said to be a symptom. Many people don’t know what causes shortness of breath. Chest tightness and shortness of breath are very common among middle-aged and elderly people. Generally speaking, chest tightness and shortness of breath are related to many reasons, especially respiratory diseases.

1. Functional chest tightness

It means that if you stay in a room with closed doors and windows and poor air circulation for a long time, or encounter some unpleasant things, or even have a quarrel or dispute with others, or are in a climate with low air pressure, you will often feel chest tightness and fatigue.

2. Cardiac neurosis

It is a kind of systemic neurosis with various symptoms. The most common subjective symptoms are palpitations, dyspnea, precordial pain and general fatigue. There are also manifestations such as irritability, insomnia, sweating, trembling, dizziness and nightmares.

3. Heart palpitations

The panic that patients feel can also be called palpitations in medicine. Palpitations are strong, rapid, and irregular beatings of our heart. Generally speaking, it is normal to have palpitations for a few minutes after strenuous exercise and there is no need to worry. If the patient feels that he or she does not have any complications, he or she can pay attention to his or her symptoms and perform some daily conditioning.

4. Nicotine stimulation

Generally speaking, if we smoke, drink too much coffee or tea in our daily life, our hearts will be stimulated by caffeine or nicotine, and arrhythmia will occur. Sometimes palpitations occur because of our mental tension or after strenuous exercise. Some people may also experience this condition due to taking certain drugs.
