Nothing says Summer like a warm-weather vacation, but chances are if you've got epic travel plans in the near future, your trip with include a bit of dreaded jet lag. Flying through time zone after time zone can wreak havoc on your body, from feeling swollen and bloated to being irritated, foggy-headed, and sleep-deprived. But what you do before can help make sure you're ready as soon as you hit the tarmac.
Drink water. Dehydration is a serious cause of jet lag. Make sure you spend the day drinking lots of water before you board the plane, and don't stop once you're there; stock up on those little bottles when the flight attendant passes through so you can regularly hydrate during your trip.
