Benefits of sighs

On average, people sigh about 12 times per hour, not because of sadness or anger, but simply to re-inflate the air for half a billion alveoli bags in their lungs.

Sustainment

According to Prevention , sighing is deep breathing twice as normal breathing. Sighs are often considered to be related to your emotions and emotions. It is also a way to stretch 2 lungs, inflate the alveoli, small pockets in the lungs, where oxygen and carbon dioxide enter and exit the blood.

Stretching and bulging are important for good lung function . "When the alveoli collapses, they will communicate to the lungs the task of exchanging oxygen and carbon dioxide," said Jack Feldman, a biologist at UCLA and one of the authors of the breath study. . " The only way to inflate them is to sigh . If you don't sigh, your lungs will gradually fade over time."

The brain stimulates the body to sigh about 12 times per hour for humans and more than animals.

The researchers analyzed the genes and found hundreds of cells that make one of the two chemicals that allow them to communicate with nerve cells that control the rhythm of the breath.

When the researchers injected these compounds, also known as "Nmb" or "Grp" , into the brains of mice, they found that mice had sighed 10 times more per hour.

These same compound samples also exist in humans, and researchers believe they also contribute to regulating sighs. Doctors can adjust these substances in patients with psychological difficulties, anxiety, stress, making them sigh too much.
