30 Nov Stay hydrated
Low humidity at high altitudes makes plane cabin air dry—and our airways more vulnerable to viruses and bacteria, says Marc Leavey, MD, primary care physician at Lutherville Personal Physicians in Lutherville, Maryland.
Staying well-hydrated keeps those mucous membranes moist so they can better keep bugs out of our systems. Down 8 ounces of water for every hour you’re in the air. Yes, that probably means using the plane’s germy lavatory (take your wipes!), but colds and flu are such monsters that you’re better off drinking than going dry.
