Symptoms of shortness of breath_What does shortness of breath feel like

Shortness of breath is a very common symptom. Many people will experience shortness of breath when they have some diseases or are in a relatively confined space. Although shortness of breath is quite common, we still need to take certain methods to alleviate this symptom in time, otherwise it will affect people's physical health and even life safety. Next, I will introduce you to some relevant knowledge about shortness of breath!

1. What is the feeling of shortness of breath?

Shortness of breath means that the breathing is shorter, rougher and more rapid than normal. If the air is blocked, the speech will be incoherent and the breathing will be forced. Shortness of breath can be divided into deficiency and excess. Deficiency is mostly caused by deficiency of the lungs, spleen, and kidneys; excess is mostly caused by phlegm and fluid blocking the lung qi.

2. Organic shortness of breath

1. Some people have had lung diseases in the past. Although they have been cured, their lung functions are affected and they often feel that they cannot inhale enough air and have difficulty breathing. This is due to the weakening of lung tissue elasticity and the narrowing of small bronchi, which reduces the breathing area of ​​the lungs.

2. Some people have poor heart function. The lungs inhale oxygen and expel carbon dioxide, which must be completed by the blood pumped to the lungs by the heart. If the heart does not function well and the blood flow pumped out is insufficient, shortness of breath may also occur. The characteristics of this type of shortness of breath are that it worsens during work, eases or disappears during rest; it worsens when lying on your back, and eases when sitting.

3. Some chronic patients may also experience shortness of breath, such as those suffering from severe anemia and diabetes.

3. Physiological shortness of breath

1. Inhibition occurs in the inspiratory center. Under normal circumstances, the human body completes the exchange of oxygen and carbon dioxide through even breathing in and out of the lungs. But sometimes, due to the accumulation of carbon dioxide in the lungs, it stimulates the excitement of the inhalation center, intensifies the inhalation, produces a short deep breath, followed by a long breath, which is a normal physiological phenomenon.

2. When working at a desk, you will feel breath holding and shortness of breath due to lowering your head to breathe. When you raise your head and straighten your body to relieve the pressure, you will take a deep breath to compensate.

3. When people are working with full concentration and high focus, but their sitting posture is not good, their breathing will be shallow for a long time, resulting in insufficient alveolar ventilation. At this time, taking a deep breath is a compensation for the shallow breathing.

4. Obese people with more abdominal fat are prone to shortness of breath because the upward and downward movement of the diaphragm is restricted, which affects the lung breathing function.

5. Some people think too much, feel depressed and in a bad mood, which sometimes inhibits the respiratory center. When the respiratory center returns to normal, they will unconsciously take a deep breath. This is the compensation between brain excitement and inhibition.
