Travel tips for staying hydrated and healthy

Moisture. Certain produce items have an exceptionally high water content, making them the perfect snack and meal items for travelers trying to stay hydrated while they beat the summer heat. Examples include watermelon, celery, broccoli, blueberries, lettuce, and grapefruit. Even if your vacation accommodations don't include kitchen facilities, you can still put this strategy to use by ordering fruit plates and salads when you dine out. For in-room snacks, consider buying crudités to enjoy with healthy dips such as hummus, salsa, or even bottled peanut sauce. You'll keep the munchies at bay while maintaining proper fluid levels at the same time.

Bottles. Carrying a full-size water bottle through airport security can prove troublesome even if you do remember to make sure it's empty. The size alone can take up precious space in your messenger bag or the side pocket of your favorite day pack. That's where collapsible water bottles come in handy for those who fly frequently. These beverage containers store flat, and can be filled up at water fountains near your departure gate, making the thirst that comes while waiting for your flight's first beverage service a thing of the past.

Timing. Erika Wiggins of the blog "The Active Explorer" recommends having a fluid-consumption plan before heading out on a long hike or other high-energy itinerary item. Wiggins, who is a trained emergency medical technician, advises drinking three to four liters of water per day for normal exertion and eight ounces every 30 minutes for more strenuous activities.
