Will asthma patients go to Hainan?

Why do northern asthma patients disappear as soon as they arrive in Hainan, but local asthma patients in Hainan can't get well?

First of all, let's analyze the factors that lead to asthma or asthma:

Definition: Asthma, also known as bronchial asthma, is a chronic airway inflammation involving a variety of cells and cellular components. The causes of asthma are: 1. Genetic factors; 2. Allergens, including: 1) indoor allergens, 2) occupational allergens, 3) drugs and food additives;

So what are the factors that induce asthma?

(1) air pollution, air pollution (SO2, NO), especially smog weather, can cause bronchial contraction, increase transient airway responsiveness and enhance the response to allergens.

(2) Smoking, cigarette smoke (including passive smoking) is the main source of indoor triggers and an important trigger of asthma, especially for asthmatic children whose parents smoke, which often leads to asthma attacks.

(3) Respiratory virus infection is closely related to asthma attack.

After arriving in Sanya, there are the following points that can alleviate the symptoms of asthma:

1. Be happy, don't underestimate this. As the saying goes, when you are in a good mood, your illness is lighter by more than half. Sanya's beautiful seascape, beautiful scenery and pure beaches have eased the depressed mood (depressed mood can easily lead to asthma attacks), so patients have obviously improved.

2. Less smog, less dust, fresh air, and the air quality of seafood is famous all over the country, which leads to fewer factors inducing asthma, which is an important reason why asthma patients pursue to settle in Sanya.

3. The air in Hainan is warm, and it is easy to catch cold in cold season, which leads to respiratory tract infection, or the sudden change of weather and the decrease of air pressure can all trigger the attack of bronchial asthma. This is rarely encountered in Hainan, so the incidence of asthma induced by cold air is reduced.
