You’ve probably heard that, because of recirculated air and close quarters, flying can increase your chances of catching a cold or the flu. So, is it true? The short answer is yes.
When travelling on a plane, you’re especially susceptible to catching a bug if you’re sitting within six feet of someone who is coughing, sneezing, or spewing germs into the air, says Bruce Polsky, an infectious disease specialist in New York City.
To increase your chances of staying healthy while travelling, Polsky recommends drinking plenty of water and using a nasal spray to keep your mucous membranes moist.
