Bronchitis every winter until breath work
His own doctor called it normal and fine, and each time came a round of antibiotics, which at the time seemed like a good idea. By the fourth year the illness was getting worse and worse.
The class had him sitting cross-legged in a cold room, breathing in a very specific rhythm. He had a meltdown, sweating profusely in ways he never had before, and for days afterward he felt really good in ways he hadn't before.
There is no control version of him, so nothing proves the class was the reason. He has not had one of those problems since, and until then he had always thought of breathing as binary, something you do or don't do. The experience pulled him into years of reporting on breath.
Why do respiratory illnesses spike in winter?
People spend more time indoors in close contact, and respiratory viruses spread more easily in shared air. Cold, dry air also slows the cilia that sweep mucus from the airways, and cold air can narrow the bronchial tubes. Acute bronchitis is caused mostly by viruses, which antibiotics do not act on, according to the US Centers for Disease Control and Prevention. Flu and RSV seasons in the Northern Hemisphere peak between December and February.
How do researchers test whether a breathing practice works?
A single person's recovery cannot show a cause, because no one can run the same year both with and without the practice. Researchers use randomized controlled trials, which assign volunteers by chance to the practice or to a comparison group and then measure outcomes in both. Some trials add a sham version of the practice, such as normal breathing in the same room, to account for placebo effects. Studies of breathing techniques in asthma have used this design.
