Deep breathing for asthma

Take a breath from asthma! scientists advise

We all do it – a long, deep breath, known as a “sigh” to express sadness, relief, or tiredness. It turns out that such sighs are important for lung function. Recently, scientists from America have identified the brain cells responsible for them.
On average, a person breathes every 5 minutes and about 12 times per hour. This is necessary for the lungs to function properly. When you take a deep breath, the alveoli of the lungs “swell up” – tiny sacs that promote gas exchange between the lungs and blood flow. When the alveoli collapse, this lung function is compromised. Then a sigh comes to the rescue, which straightens the collapsed alveoli and brings twice as much air as with normal breathing. The researchers found about 200 neurons in the brainstem that control breathing. This information could one day help people who have difficulty breathing and those with asthma. Summary: a deep breath is useful for asthma, and not holding the breath, as Buteyko once advised!
