A health warning has been issued to millions of individuals in the UK diagnosed with asthma. The National Health Service (NHS) states that asthma is a prevalent respiratory condition without a cure but can be effectively managed with medications like inhalers to relieve symptoms.
Statistics from Asthma and Lung UK reveal that approximately 7.2 million people in the UK have asthma, equating to about eight out of every 100 individuals. Common symptoms of asthma include wheezing, breathlessness, coughing, and chest tightness, with some experiencing sudden worsening of symptoms known as asthma attacks.
People with asthma often notice that changes in weather conditions, especially cold temperatures, can trigger their symptoms due to the irritant nature of cold, dry air on the airways. Presently, the UK is experiencing severe wintry weather conditions with multiple Met Office snow and ice warnings in effect across various regions, leading to temperatures nearing freezing levels.
In light of the harsh weather, Dr. Neel Patel, a part-time NHS GP and LloydsPharmacy Online Doctor consultant, has cautioned asthma sufferers, particularly those aiming to maintain an active lifestyle during the cold season or pursuing New Year fitness goals. Dr. Patel highlights lesser-known signs of Exercise-Induced Bronchoconstriction (EIB) and offers advice on managing asthma in cold weather to individuals seeking to stay active while preventing shortness of breath.
Research from LloydsPharmacy Online Doctor indicates that 64% of individuals find it harder to control their breathing while exercising in cold weather, with an additional 66% reporting quicker breathlessness onset. Despite these challenges, individuals with asthma may face exacerbated symptoms during winter. Dr. Neel Patel advises on coping strategies for asthma management in cold weather and offers suggestions for maintaining physical activity without exacerbating breathing difficulties.
Emphasizing the risks of winter exercise, Dr. Patel explains that cold, dry air can exacerbate lung conditions like asthma, with a large percentage of individuals reporting worsened symptoms due to cold air exposure. Cold air irritates the airways, leading to increased mucus production and narrowed airways, making breathing difficult. Furthermore, cold weather weakens the immune system, making individuals more susceptible to respiratory infections like colds and flu.
In addition to the impact of cold air on respiratory health, the dry indoor air from heating systems during winter can create conditions that allow germs to enter the body through the nose, potentially leading to infections. Reduced sunlight exposure in winter can also lower vitamin D levels, crucial for a robust immune system.
Recognizing the signs of an asthma attack, which include coughing, wheezing, breathing difficulties, and chest tightness, Dr. Patel advises individuals to remain physically active during winter while being mindful of potential triggers and taking necessary precautions. Key recommendations include consistent use of controller medicines, keeping a quick-relief inhaler handy, breathing through the nose, and wearing a scarf to warm up the air before breathing in.
Exercise-induced bronchoconstriction (EIB), a form of exercise-induced asthma affecting up to 90% of asthma patients, can manifest even in individuals without asthma due to cold air’s drying effect on the airways during physical activity. Dr. Patel stresses the importance of recognizing EIB symptoms, seeking medical advice, and exploring treatment options to manage this condition effectively.
Highlighting common EIB triggers like polluted areas, outdoor sports, and indoor environments with chemical irritants, Dr. Patel reassures that with appropriate treatment plans, individuals can overcome EIB challenges and continue engaging in physical activities. Diagnosis involves breathing tests and monitoring airway responses during exercise, with prescription inhalers and symptom tracking recommended as part of the management strategy.
