Is rheumatic heart disease related to the weather?

First, in rainy weather, the temperature tends to drop; The decrease of air pressure and the increase of humidity are the main reasons for the aggravation of local pain in arthritis patients, and the change of humidity plays a major role. Because rainy days are cold and humid, when the human body is cold, it first acts on the skin cold receptors, and then spreads to the brain center through nerve reflex, and then the skin, muscles and small blood vessels contract, and the blood flow in the blood vessels slows down, so there will be "goose bumps" on the skin, which is called "hair muscle contraction" in medicine, which will reduce the human body's tolerance to pain and aggravate local symptoms. In addition, the change of humidity has a great influence on the surrounding tissues, which can make blood vessels dilate and congestion, and this change is also the reason for the aggravation of symptoms when the weather changes. In addition, humidity can increase heat conduction by 20 times, and when people's clothes are wet by rain, the heat in their bodies will dissipate much faster. Because cold invades the body faster, people are prone to catch cold and get sick. If it is rheumatic heart disease, chest tightness and shortness of breath are easy to attack. Some scholars have observed that if the average temperature of the day is compared with the average temperature of the next day, it will rise or fall by more than 3℃; If the air pressure increases or decreases more than 10 millibar in a few days and the daily relative humidity changes more than 10%, the incidence of rheumatic heart disease will increase obviously.

Second, some scholars believe that there is a potential difference between positive and negative charges inside and outside human cells, and normal people always maintain a relative balance. In the large airflow, due to the difference of atmospheric molecules with positive and negative charges, they attract and collide with each other, resulting in electromagnetic waves. Electromagnetic waves in atmospheric molecules are continuously transmitted at a speed of 300,000 kilometers per second. Abnormal electromagnetic waves generated when the weather changes cause the potential changes of positive and negative charges in human cells, thus destroying the relative balance in the body. Arthritis patients are affected by the changes of temperature, air pressure and humidity, which will lead to congestion, edema and exudation of inflammatory substances in the body, changes in tissue microcirculation, physical and chemical stimulation of peripheral nerves, increased heart load, and patients with rheumatic heart disease will feel chest tightness and shortness of breath.
