Upper respiratory infections are more common in the winter because cold air slows down our immune response. Keeping our nose warm may help. Cold, flu, winter,
Harvard Medical School researchers have discovered an immune response inside the nose that fights off viruses and that cold weather reduces this immunity.
New research suggests that cold weather may actually affect the human body's immune response, making us more susceptible to colds, flus and other upper respiratory infections. Dr. Benjamin Bleier, a sinus specialist at Mass Eye and Ear and a senior author of the study, joins John Yang to discuss its findings.
A recent study observed that the nose, which is equipped with defences to stop invaders from attacking the body, has something to do with a person catching the common cold in winter.
