Nurses’ Note:
Breathe easy: How to have a wheeze-free winter.
Cold weather can be tough for those who suffer from asthma, especially when exercising. Cold air is a common trigger of “bronchoconstriction,” or narrowing of the airways. One of the simplest things asthmatics can do to make cold weather breathing easier is to “rewarm the air you breathe,” according to Sumita Khatri, MD, co-director of Cleveland Clinic’s Asthma Center. Whenever you’re outdoors, wrap a scarf, neck gaiter or bandanna loosely around your nose and mouth to effectively trap your warmer exhalations. Bonus: Keeping your nose warm may also reduce the number of colds you catch this winter. A small animal study found that the rhinovirus — a cause of the common cold — replicates better inside a cold nose.
