Sleep In

A recent study by Carnegie Mellon researchers revealed that insomniacs and short sleepers are nearly three times as likely to catch a cold as their better-rested counterparts. “Getting adequate sleep before, during, and after a trip is essential,” says Case Western Medical Center’s Vanessa Maier, M.D., M.P.H. “A tired immune system is a weak immune system.” In addition, sleep helps keep constant the body’s levels of cortisol, a hormone that can boost the immune system. Aim for at least seven hours a night, and at least eight the night before any flight.
