Start with your choice of drink. Staying hydrated, and staying away from both caffeine and alcohol, can also help reduce jet lag. Some people have even found that preparing for jet lag before you set foot on a plane is the key. If they know they are going to a destination that is two hours earlier than the place they call home, they adjust to the change ahead of time. For example, a few days before they fly, they may get up two hours earlier, or go to bed two hours later. Simply staying healthy can also decrease jet lag. Exercise and a balanced diet can keep it at bay.
For the frequent flier, and even the infrequent flier, jet lag may just come with the territory. Up there with lost luggage and delayed flights, jet lag is part of flying. Taking a few preventative measures, however, may help keep it from taking flight.
