Medical experts explain causes and prevention of winter asthma flare-ups

Winter air and circadian rhythms can cause nighttime asthma symptoms and wheezing to worsen due to airway constriction and increased allergen exposure.

Dr Manisha Mendiratta notes that cold air triggers bronchospasm while indoor time increases contact with dust mites, mold, and pet dander.

Patients are advised to cover their noses outdoors, maintain clean indoor spaces, monitor air quality, and keep rescue inhalers accessible.
