Asthma does not follow a calendar, although many people notice that their symptoms do. A change in weather, a dusty room after the windows have been closed for weeks, pollen in the air, smoke, pollution or a respiratory infection can all make already-sensitive airways react. For someone with asthma, this may mean more coughing, wheezing, chest tightness or breathlessness at certain times of the year.
The important thing is to understand what actually triggers an individual's asthma. Two people may both have asthma but respond to very different things. One may struggle when the weather turns cold, while another may notice symptoms during the rainy season, around dust or mould, or whenever air pollution rises.
Why Can Weather Changes Affect Asthma?
Asthma causes inflammation and narrowing of the airways, making them more sensitive to irritants and other triggers. Seasonal changes can bring several of these together.
- Cold, dry air may irritate the airways, particularly during outdoor activity.
- Rain and humidity can encourage mould growth, while changes in temperature may aggravate symptoms in some people.
- Seasonal infections such as influenza and other respiratory infections can also worsen asthma.
In Indian cities, there is another consideration: air pollution and dust. Pollution and exposure to biomass fuel can contribute to respiratory problems, alongside conditions such as asthma and COPD.
Asthma Triggers Can Change With the Season
Rather than trying to avoid every possible trigger, it helps to notice patterns in your own symptoms.
- Summer: heat, pollution, dust and sudden temperature changes may be troublesome for some people.
- Monsoon: damp surroundings and mould can become relevant triggers, while viral respiratory infections may also circulate.
- Winter: cold air and respiratory infections can aggravate asthma symptoms.
- Spring and other pollen-heavy periods: pollen and other airborne allergens may cause problems in people with allergic asthma.
- Throughout the year: cigarette smoke, incense, strong fumes, household dust and other irritants can affect sensitive airways.
A simple record of when symptoms appear, where you were and what you were exposed to can sometimes be surprisingly useful during a medical consultation.
What Can You Do to Keep Asthma Under Control?
Living with asthma does not mean staying indoors whenever the weather changes. It is more about knowing your triggers and keeping the condition properly managed.
A few practical measures can help:
- Take prescribed asthma medicines regularly and use inhalers with the correct technique.
- Keep rooms clean and reasonably well ventilated, particularly where dampness or mould is present.
- Avoid cigarette smoke and minimise exposure to dust, fumes and other known irritants.
- If outdoor air quality is poor, consider limiting strenuous outdoor activity and follow local air-quality advice.
- During periods when respiratory infections are circulating, maintain sensible infection-prevention measures.
- Discuss recommended vaccinations with your doctor. Annual influenza vaccination and pneumonia vaccination should be part of adult respiratory care.
- Do not stop long-term asthma medication simply because you are feeling better unless your doctor advises you to do so.
For children, seasonal symptoms can sometimes be mistaken for repeated "colds". Persistent coughing, wheezing or breathlessness deserves proper evaluation, especially if it keeps returning.
When Is It More Than a Seasonal Problem?
There is a difference between an occasional cough during a change in weather and asthma that is poorly controlled. Needing a reliever inhaler frequently, waking at night because of coughing or breathing difficulty, struggling with routine physical activity, or having repeated flare-ups should prompt a review of treatment.
A severe episode with marked difficulty breathing, inability to speak comfortably, bluish lips or severe exhaustion requires urgent medical attention.
It is also worth remembering that wheezing is not automatically asthma. Allergies, infections and several other respiratory conditions can produce similar symptoms. Getting the diagnosis right is the first step towards choosing the right treatment.
Asthma Care at STAR Hospitals
At STAR Hospitals, Hyderabad, asthma is managed through its Pulmonology services, with care extending from diagnosis to long-term respiratory management. The department specifically treats asthma and other airway diseases and offers investigations such as pulmonary function tests, spirometry, chest X-rays, CT scans and allergy testing, depending on the patient's symptoms and clinical needs.
Its respiratory services include:
- Inhaler therapy for asthma
- Pulmonary function testing and spirometry
- Allergy testing where appropriate
- Medication and steroid therapy when clinically indicated
- Pulmonary rehabilitation
- Oxygen therapy and positive-pressure ventilation for patients who require them
- Smoking cessation support
- Specialist care for complex respiratory conditions and severe asthma
STAR's pulmonology team also includes specialists who list asthma management among their areas of expertise. For example, Dr Bhavana specializes in asthma and COPD management, pulmonary function testing and non-invasive ventilation while Dr Anuradha T has asthma and COPD among her areas of practice.
Seasonal changes cannot always be avoided, and neither can every trigger. What can be managed is how prepared the airways are to deal with them. With an appropriate treatment plan, awareness of personal triggers and timely medical review when symptoms change, people with asthma can continue their usual routines through the changing seasons.
