> Is it good for your health to sigh often?

Research on respiratory physiology has found that when a person inhales enough, the expansion of the lungs can reflexively inhibit the inhalation center, so exhalation follows. However, under certain circumstances, the lungs that are already in an expanded state can briefly stimulate the inspiratory center, resulting in one or two deep sob-like inhales, which will naturally lead to exhalation (sighing).

In fact, long sighs are a normal physiological phenomenon. Long sighs and short sighs can make the diaphragm rise in the body, promote the lungs to expel turbid air, increase lung capacity, increase the oxygen content of the blood, speed up blood circulation, and make the body In a relaxed state, the excitement and inhibition of the brain tend to be coordinated, which can eliminate sadness, pain, tension, anxiety and mental depression, thereby benefiting the regulation and stability of the internal environment of the body, and allowing the body's internal organs to be fully utilized. Some people have even observed that long sighing movements in infants are beneficial to the expansion and development of the lungs. If an adult cannot help but sigh once or twice after breathing calmly for a period of time, it will have a good promotion effect on pulmonary gas exchange. In addition, observations have also found that people who often sit and work are prone to intermittent sighing, especially after a period of concentrated mental work. This situation is more common.

This is caused by the relative lack of ventilation caused by sitting posture and high concentration of energy, and this kind of sighing is often involuntary. Some people often sigh spontaneously due to overthinking or feeling unhappy, and often feel a heavy pressure on their chests. However, after a few long sighs, the breath-holding phenomenon will be relieved a lot.

Sighing is a bad habit with the following harms: 1. Sighing for a long time gradually forms a psychological suggestion that makes people less optimistic. 2. Let people around you think you have long-term doubts
