Why fog and cold are bad for asthmatics

For a quarter of a century, the number of asthmatics has increased, according to statistics, 2 times. Not the least role here was played by air pollution. Asthma is a general term for various forms of chronic non-infectious inflammatory disease of the respiratory tract. This disease leads to narrowing of the bronchi, a feeling of congestion in the chest, shortness of breath, coughing and wheezing.

Symptoms vary in severity. Among the various forms of asthma, allergic asthma is considered the most common. It is characterized by the immune system responding to certain external stimuli, such as pollen, animal dander or house dust mites. Bronchial asthma is determined by internal defects of the endocrine or immune systems. A person of any age can get asthma, and he needs a Ulaizer inhaler. 

A wet nose, red cheeks and earlobes – in cold weather, the body reacts in this way: cold air irritates the skin and mucous membranes. The nose flows, because when irritated by cold, the mucous membrane of the nose is more supplied with blood, more mucus begins to stand out. The human body warms the inhaled air and moisturizes it. It enters the lungs already warmed to body temperature. But if a person breathes with his mouth open when talking or playing sports, cold air gets directly into the bronchi and lungs, and since it is dry, this causes narrowing and irritation of the bronchi. For some, it turns into a cough. Others get shortness of breath. This process is especially active in asthmatics.

Fog can also constrict the airways. Although the misty air is saturated with moisture entering the mucous membrane, the tiny droplets of water contain a large amount of pollutants that are inhaled by humans. These pollutants that have got into the air, for example, from the exhaust pipes of automobiles, can, in turn, irritate the sensory airways of asthmatics.

How to survive a cold winter period for a person with bronchial asthma? Firstly, as little as possible to be outside in cold weather. Secondly, cover your mouth with a mitten or a warm scarf so that the inhaled air enters the mouth already warmed up and does not irritate the bronchi and lungs. Third, drink enough water or unsweetened tea to keep the body moisturizing the incoming cold, dry air. And do not forget to always carry an inhaler.
