Asthma patients have increased difficulty in breathing in winter. A sudden cold or viral attack can also cause shortness of breath. Asthma patients need caution until winter.
Asthmatic airways are oversensitive. As a result, exposure to irritants such as house dust, cigarette smoke, industrial chemicals or gases, cold air, pollen from flowers or animals can cause sudden narrowing of the patient’s airways and severe shortness of breath. The things to which the airways are sensitive are called asthma triggers or allergens. These allergens can be different from person to person. Stay away from them.
Asthma is a chronic disease. Its exact cause is yet to be identified. But it is not contagious and contagious disease.
