Asthma is a long-term condition affecting the lungs and other airways in children and adults. As per a 2019 study, around 262 million people worldwide are affected by this condition [1]. Among the different types of asthma, winter asthma is a condition which can trouble individuals with asthma badly. Read on to learn about asthma in the cold and its risk factors, and find out how to manage it efficiently.

What is Winter Asthma?

Asthma and cold weather are known to come hand in hand. For people with asthma, winter is usually the most challenging time of the year. The cold and dry climate of winter, accompanied by frequent changes in weather, can affect your airways. As a result, your respiratory system starts producing more mucus, which blocks a part of your airways, causing winter asthma. In addition, there may be mild or severe asthma attacks based on your condition and preventive or treatment measures taken.

Why Asthma Gets Worse In Winter

Though individuals with asthma may experience symptoms throughout the year, there is nothing worse than asthma in the cold. In cold weather, there are always the following risk factors for winter asthma:

Dry air

Due to the lack of humidity, cold air dehydrates your body in no time. Unfortunately, in the process, the layer of fluid that guards your airways gets evaporated, leading to irritation and swelling in your airways.

Respiratory infections

There is another protective layer of your airways, which is formed by mucus. In dry and cold weather, the layer of mucus thickens and blocks your airways. As a result, you may get respiratory illnesses such as the flu or the common cold. These conditions may irritate and inflame your airways, triggering asthma symptoms.

Exposure during outdoor exercise

Daily morning walks or jogs may also become a possible risk factor for asthma during winter. As you breathe in cold air during your outdoor exercise, there are high chances of catching a cold with associated conditions like cough, headache, and breathlessness.

Common Winter Asthma Triggers

When it comes to preventing, managing, or treating winter asthma, the first step is identifying the triggers. During this time, the following objects or conditions play a crucial role in triggering asthma:

  • Dust mites
  • Cold weather
  • Respiratory infections
  • Mould
  • Pet dander (as you spend more time at home) [2]

Winter Asthma Treatment

Remember, no treatment can cure asthma, but there are remedies for effectively managing the condition. Oxygen therapy and bronchodilators are two of the most common treatments for asthma. In case of severe asthma, doctors may also recommend steroids. Major bronchodilators and steroids are available as tablets, syrups, and inhalers.

Once doctors come up with an Asthma Action Plan for you, it is prudent to follow it thoroughly. For example, if you are given an inhaler for asthma management, don’t stop using it when you feel better. These inhalers usually continue throughout the year to keep your asthma symptoms in check. Apart from that, it is essential to ensure the following:

  • You are keeping your prescriptions updated
  • Your Asthma Action Plan covers how to manage the condition when you have mild and severe symptoms or no symptoms at all
  • Keep a note of your triggers, symptoms and medications. This can help doctors get a comprehensive idea of how the condition affects you

Why is cold weather bad for people with asthma?

  • Erratic weather: Due to the dry air and fluctuations in temperature throughout the day, the winter in India becomes a difficult time for people with asthma
  • Ailments: There are high risks of getting cold and flu during winter, and both can cause your airways to swell up. In such a situation, small triggers of asthma can cause big troubles
  • Time spent indoors: During winter, it is quite common to spend extra time at home due to extreme weather conditions. However, this exposes you to indoor allergens such as dampness, mould, dust mites, and pet dander. Make sure to change and clean your bedding regularly to prevent allergens from settling in

Does outdoor exercise trigger winter asthma?

Yes, outdoor exercise is one of the key triggers of winter asthma. However, if it is a thing you cannot avoid, it is wise to do a warm-up indoors before leaving home for the workout.
