Q: Does alcohol affect you more when you drink on an airplane?
A: In a word, yes. Changes in air pressure, fatigue from flying, and especially dehydration all cause alcohol to be more potent than usual, says Eric Rimm, ScD, associate professor of epidemiology and nutrition at the Harvard School of Public Health.
“Since there’s less water in your blood when you’re dehydrated, the concentration of alcohol will be slightly higher, leading to quicker intoxication and increased potential for a hangover,” Rimm says. “Stick to one drink—and down lots of water.”
