Winter can be challenging for people living with asthma, as colder air and seasonal respiratory infections may trigger symptoms or worsen breathing difficulties. Influenza, commonly known as the flu, can pose additional risks for people with existing respiratory conditions, making prevention and early care especially important.
Why Winter Can Worsen Asthma
Cold, dry air can irritate sensitive airways and trigger coughing, wheezing, chest tightness and breathlessness in people with asthma. Seasonal viruses, including influenza, may also inflame the respiratory tract and increase the risk of an asthma flare-up.
For some people, an infection can lead to more severe symptoms and a greater need for medical attention. Recognising early warning signs and following a healthcare professional’s advice can help reduce complications.
The Importance of Influenza Prevention
Flu prevention is particularly important for people with asthma because respiratory infections can aggravate the condition. Annual influenza vaccination is an important preventive measure, in line with a healthcare professional’s recommendation.
Regular handwashing, avoiding close contact with people who are unwell and maintaining good ventilation can also help reduce the spread of respiratory viruses.
Managing Asthma During Winter
People with asthma should continue taking prescribed controller medication and keep their reliever inhaler accessible, following their personal asthma action plan. They should not stop or change medication without medical advice.
When heading outdoors in cold weather, covering the nose and mouth with a scarf may help warm the air before it is inhaled. Adequate rest, hydration and avoiding known triggers can also support respiratory health.
When to Seek Medical Help
Persistent wheezing, worsening breathlessness or symptoms that do not improve with prescribed reliever medication require prompt medical advice. Severe difficulty breathing, inability to speak in full sentences or bluish lips can indicate an emergency and require immediate medical attention.
Preparing ahead of winter, staying up to date with recommended vaccinations and following an asthma management plan can help people reduce avoidable risks and protect their respiratory health.
