We’ve all heard stories of summer vacations gone awry. Depending on where and how you travel, health risks can range from poison ivy and mosquito bites to dehydration and deep vein thrombosis. With a few simple precautions, however, you can make your vacation memorable for all the right reasons.

Before you pack, make a list of your current prescriptions and their dosages. Bring extra doses, in case you get unexpectedly delayed.

“It’s also a good idea to bring a supply of allergy medications, poison ivy treatments and over-the-counter remedies for insect bites,” says Jerrold Gertzman, MD, a family practice physician at Hunterdon Medical Center.

Next, think about your destination. If you’ll be outdoors, bring sunscreen, insect repellent and a refillable water bottle.

During the trip, move around every hour or two that you’re sitting in the car or on the plane. These frequent stretch breaks improve circulation and reduce the risk of life-threatening blood clots, also called deep vein thrombosis.
