I feel short of breath these days.

Analysis of illness: According to your description, it is a symptom of shortness of breath.

Suggestion: shortness of breath has organic and physiological differences. Organic for three reasons:

1, some people had lung diseases in the past, although they were cured, their lung function was affected, and they often felt insufficient inspiration and difficulty breathing, which was caused by the weakening of lung tissue elasticity, narrowing of bronchioles and reduction of lung breathing area.

2. Some people have poor heart function, and their lungs inhale oxygen and expel carbon dioxide, which must be done by pumping blood from the heart into the lungs. If the heart function is not very good and the blood flow pumped out is insufficient, shortness of breath will also occur. This shortness of breath is characterized by aggravation during labor and alleviation or disappearance during rest; The supine position is aggravated and the sitting position is reduced.

3. Some patients with chronic diseases will have shortness of breath, such as severe anemia and diabetes.

Physiological shortness of breath is also called transient shortness of breath. The reasons for this shortness of breath are:

1, the inspiratory center has been suppressed. Under normal circumstances, the human body completes the exchange of oxygen and carbon dioxide through uniform breathing and inhalation in the lungs. However, sometimes due to the accumulation of carbon dioxide in the lungs, it stimulates the excitement of the inspiratory center, which intensifies inhalation, produces short-term deep inhalation, and then appears the phenomenon of long-term breathing, which is a normal physiological phenomenon.

2. When you work at your desk, you will feel suffocated and short of breath because you bow your head and breathe. When you stand up to relieve depression, there will be a compensatory phenomenon of deep breathing.

3. When people are highly concentrated on their work, their sitting posture is not good. Because they are in a superficial state for a long time, alveolar ventilation is not enough. At this time, deep breathing is the compensation for shallow breathing.

4. Obese people with more abdominal fat are prone to shortness of breath because the upper and lower activities of the diaphragm are restricted, which affects the respiratory function of the lungs.

Some people are depressed and in a bad mood because of overthinking, and sometimes they suppress the respiratory center. When the respiratory center returns to normal, they will take a deep breath unconsciously, which is the compensation between the excitement and inhibition of the brain.

Physiological shortness of breath caused by the above different reasons has nothing to do with the heart. As long as we pay attention to the law of life, combine work and rest, and exercise properly, shortness of breath will disappear.

I hope it helps you.
