So what's a traveler to do?

While we can't promise you'll eliminate jet lag altogether, try beating it with these simple tips (yes, they do work!):

• Wear comfortable layered clothing onboard so you can adjust yourself comfortably to the cabin temperature as the trip goes along.

• We suggest that (on long flights) you wear soft and flexible shoes onboard, and bring slipper socks to keep comfortable (feet swell in the air). Be sure to get up and WALK every hour or so to keep the circulation going in your body, and you may keep the swelling down to a minimum.. Remember to put your shoes back on at least a half and hour before landing or you may have trouble getting them back on!

• The super-dry air will dehydrate your body and your skin. Drink plenty of WATER during the flight, even if you don't feel thirsty. Carry a tube of moisturizer (particularly if the flight is very long) and a small spray bottle of sterile water (E.g. Evian). Use them often on your face and hands during the flight to keep them hydrated (it feels great too!)

• Drinking alcohol may make the flight speed by, but you'll hate the way you feel whenyou "come back to Earth." The effects of drinking are magnified at high altitudes, and alcohol also dehydrates you. Resist the urge to drink alcoholic beverages during the flight.

• Bring some healthy snacks and avoid the airplane food

• Bring earplugs or a walkman to drown out cabin noises. If possible, skip the movie and get some sleep!
