There's no reason to finish a flight feeling like you've been through the ringer! Stay healthy while you fly by avoiding alcohol and caffeinated drinks. Both are extremely dehydrating, and air cabins-as your skin knows-are dry enough as it is! Finally, a reason to be glad that airlines have given up on meals! You'll feel better if you avoid eating a heavy meal during and before the flight. Instead, bring light snacks like fruit or pretzels. Make it a point to get up and walk for about five minutes every hour. If you're not allowed to walk, prop your feet on your carry-on bag. Rotate your ankles and lift your knees while seated. An insider tip is to invest in a pair of elastic flight socks, available at most pharmacies. These socks apply pressure to the ankle, in turn squeezing blood up towards the heart, which assists in circulation. Follow these tips and you can actually spend time enjoying your destination-not dreading your return home!
