Most of the allergens that cause asthma are transmitted through the air, and to create a state of sensitivity, it is necessary that they are present in sufficient amounts in the air; after the sensitivity is created, the patient will show a stronger reaction to the allergen in the next encounters. It gives so that small amounts of allergens will cause significant aggravation of the disease.
This type of asthma caused by allergens is called allergic asthma; It is often seasonal and is commonly seen in children and young people.
2- Medicinal triggers: Some people who have asthma are sensitive to aspirin use and its use in these people causes an asthma attack.

5- Infections: Respiratory infections are the most common cause of acute asthma attacks. Research has shown that respiratory infections of viral origin cause acute asthma attacks and there is no evidence to show that bacterial infections play a role. have in this phenomenon.
6- Exercise: Physical activity can cause asthma and may also aggravate an asthma attack. Inhaling cold air during exercise significantly increases the severity of asthma attacks, while inhaling hot and humid air may reduce or stop asthma attacks.
