by | Nov 4, 2021 | UrgentWay Blog

The winter season is the time of get-togethers, family dinners, and enjoyment, but winter can take your breath away if you have asthma because asthma in winter season is worse. Asthma is a long-term disease of the lungs in which your airways narrow and swell and may produce extra mucus. This condition can cause wheezing, coughing and difficulty in breathing. It can’t be cured, but it can be controlled. In the winter season, cold air contains moist, harboring mold spores and dust mites, which cause your airways to seize up and bronchial passageways to spasm and close off, resulting in worsening asthma.



What are the winter asthma triggers?

People with asthma often find that asthma in winter season gets worse. It is due to the several winter asthmas triggers around them as given below:

  • Cold weather
  • Colds and flu
  • Chest infections
  • Damp and mold
  • Dust mites
  • Central heating, open fires and wood-burning stoves


Why is asthma in winter season worse?

Symptoms of asthma in winter season get worse due to the following reasons:


i. Dry atmospheric air

A layer of fluid encloses and protects the airways of your lungs. When you breathe in cold air, the layer of protected fluid evaporates, causing your airways to become inflamed and irritated, which trigger asthma in winter season.

ii. Respiratory illness

A layer of mucus protects your airways in the lungs. When you inhale cold air, this layer of mucus can thicken, increasing your chance of getting respiratory infections like the common cold, chest infection or flu. These respiratory infections may cause swelling and irritation of your airways, which trigger asthma in winter season.

iii. Exercise

Exercise may also be a triggering factor because exercise requires increased lung capacity. When you walk and breathe in cold air, your airways can become restricted, triggering symptoms such as cough and breathlessness.

iv. Mold and mites

If you’re allergic to mold and mites, then your asthma in winter season can get worse because mold spores are often found in our air in the winter season. When you inhale air, these spores enter your respiratory system and cause infection, which triggers asthma symptoms in winter season.

v. Open fires and wood-burning stoves

Open fires and wood-burning stoves release pollutants in the air as COx, SOx, NOx, and particulate matter, which could worsen your asthma symptoms on inhalation.
