Why is it easy for chronic diseases to recur and worsen when the weather changes?

Many chronic diseases, such as low back pain, leg pain, gastric ulcer, tracheitis, hypertension, etc., are easy to recur and worsen before the weather changes. This is because before the weather changes, the concentration of ions in the atmosphere has changed, such as potassium, sodium, calcium, magnesium and chlorine. Like photons, it travels in the atmosphere at a speed of 300 million light-years per second. So, the weather here has not changed. The ions in the atmosphere have changed. But when there are chronic diseases, if there is pleurisy, you will feel chest tightness and shortness of breath, and if there is stomach trouble, stomach pain will recur; People with coronary heart disease will have chest tightness and chest pain; If you have chronic enteritis, diarrhea will recur, and so on. Therefore, when the weather changes, we should prevent chronic diseases and avoid recurrence.
