By eigindia However, the more common is winter asthma or acute exacerbation of winter COPD (chronic bronchitis). Asthma is reversible airway obstruction and COPD is irreversible airway obstruction. Sudden exposure to cold, humidity, pollution at lower levels in atmosphere can precipitate asthma or worsen COPD symptoms. Cold air can cause bronchospasm, leading to wheezing, coughing, and breathlessness in asthma patients. Similarly, in individuals with COPD, the cold weather can increase mucus production, trigger inflammation, and make it harder to breathe.
Other contributing factors include viral infections, which are more common in winter, and indoor heating, which can dry out the airways, making them more susceptible to irritation. To prevent exacerbations, patients are advised to wear scarves over their noses and mouths to warm the air before inhaling, use humidifiers indoors, and adhere to their prescribed medications, including bronchodilators and inhaled corticosteroids.
If symptoms worsen despite these measures, medical intervention may be necessary, including the use of nebulizers, oxygen therapy, or hospitalization in severe cases. Recognizing early warning signs and seeking timely treatment can help prevent serious complications during the winter months.
