Exercising

Work out. Ask if your hotel has an exercise room or provides free use of a nearby club. A workout, even a small one, can do wonders when you're traveling, especially if you are eating heavy meals.

Take it easy. On the other hand, don't be a vacation superjock. Unless you are in peak physical condition, do not engage in any strenuous physical activity while on vacation that you do not regularly do at home. Too many vacations are ruined by sprained or strained or broken body parts because someone got a little too adventurous or tipsy.

Take a quick spin. If you like to jog, take a run and you'll get a mini-sightseeing adventure. A run through the countryside is often a rewarding experience.

Have a good chew. When hiking or camping with a limited or rationed water supply, chewing on gum, particularly with electrolytes, helps to moisten the palate, relieving that "parched" feeling.
