& gt Is sighing often good for your health?

The study of respiratory physiology found that when people inhale enough air, the inspiratory center will be suppressed reflexively due to the expansion of the lungs, so the exhalation action will also occur. However, in some cases, the lungs that are already in an expanded state can temporarily stimulate the inspiratory center and produce one or two deep breaths similar to sobbing, which will naturally lead to long-term breathing (sighing).

In fact, sighing is a normal physiological phenomenon. Sighing can make the diaphragm rise in the body, promote the discharge of turbid gas in the lungs, increase vital capacity, increase blood oxygen content, speed up blood circulation, make the body in a relaxed state, make the excitement and inhibition of the brain tend to be coordinated, and eliminate sadness, anxiety and depression, thus contributing to the adjustment and stability of the internal environment of the body and giving full play to the functions of viscera. It has even been observed that if it happens to babies, long-term sighing will be beneficial to the expansion and development of the lungs. If adults can't help sighing once or twice after breathing quietly for a period of time, it will promote gas exchange in the lungs. In addition, it is found that people who often sit and work tend to sigh for a long time, especially after a period of concentrated mental work.

This is due to sitting posture and high concentration of energy, which leads to relatively insufficient ventilation. This sigh is often involuntary. Some people often sigh spontaneously because of overthinking or depression, and there seems to be a sense of oppression in their chests, but as long as they sigh lightly, the phenomenon of holding their breath will be alleviated.

Sighing is a bad habit, and its harm is as follows: 1 Sighing for a long time will gradually form psychological hints and make people become pessimistic. Let people around you think that you have long-term doubts.
