Respiratory Infections and Winter Cough
Winter is a peak season for various respiratory infections such as the common cold, influenza, and more recently, COVID-19. These infections often present with cough as a primary symptom. The cold weather can facilitate the survival and transmission of these viruses.
Dry, Cold Air:
Cold air is typically dry and can irritate the airways, leading to a persistent cough. For individuals with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), this can exacerbate symptoms.
Indoor Air Quality:
During the winter months, people tend to spend more time indoors with windows closed, increasing exposure to indoor allergens such as dust mites, pet dander, and mold, as well as irritants like smoke and fumes from heating appliances. This can further aggravate cough symptoms.
Seasonal Allergies:
Some individuals may have allergies to indoor allergens that are more prevalent in winter, which can contribute to cough.
Post-COVID Pandemic Behavior:
With the relaxation of COVID-19 precautions, such as wearing masks, practicing hand hygiene, and maintaining social distancing, there has been an increase in cross infections and prolonged illnesses associated with cough. The reopening of schools, offices, and increased social interactions have contributed to this trend.
