Sure, it might not technically be food, but water is perhaps the most important item on this list. Flying can severely dehydrate you due to low humidity levels in the cabin, so it's vital to increase your water intake. "Drinking lots of water prevents bloating, headache, and fatigue," Mimi Secor, DNP, cofounder of the health and fitness program Coach Kat and Dr. Mimi, told POPSUGAR. "Also, avoid caffeine and alcohol because both can cause headaches, fatigue, irritability, and contribute to jet lag and poor sleep. If I'm craving alcohol or a soda, I order club soda with lemon or lime."
Eudene Harry, MD, medical director of Oasis Wellness and Rejuvenation Center, recommends coconut water for best results. "Coconut water provides double the benefits: hydration and high potassium," she explained. "Both hydration and potassium help keep muscles from cramping and your energy level up."
So, how much should you drink? The Aerospace Medical Association recommends eight ounces of water for every hour you're in the air. Grab a refillable water once you've cleared security, and ask your flight attendant to keep the water coming.
