For patients with chronic bronchitis, it is necessary to improve their adaptability to external temperature changes and enhance their disease resistance. Especially insist on cold-resistant exercise. The method is to rub the exposed parts of the head, face and upper and lower limbs by hand several times a day for a few minutes at a time until the skin turns red. In summer, use a cold water towel, wring it out and rub it all over your body, 12 times a day, and wash your nose with cold water; After beginning of autumn, wash your face, wipe your body, or take a cold bath with cold water, and persevere. In addition, you can practice breathing exercises, because deep breathing exercises not only exercise the respiratory muscles, but also change the changes of lung pressure, force the residual gas in alveoli to be discharged, increase the ventilation volume, and are also very beneficial to the elastic recovery of alveolar tissue. It is best to choose lakes, Woods and parks.

I hope I can help you. I wish you a speedy recovery and a happy life!
