Summer travel is meant for making memories, not managing a surprise illness along the way. Whether you’re heading through busy airports, relaxing at a resort or setting sail on a cruise, a little preparation can go a long way in helping you stay healthy during your travels.
Dr. Parul Aneja, an infectious disease specialist with BayCare, says most travel-related illnesses come down to a few common factors: exposure to germs in the air, contact with contaminated surfaces and what we eat or drink. In some cases, insects can also play a role in spreading infections.
The good news? Most of these risks are manageable and can be reduced with a few practical steps.
Know where germs like to travel
Crowded, high-traffic spaces like airports, airplanes and cruise ships make it easier for germs to spread. Close quarters mean you’re sharing air, surfaces and occasionally space with someone who may not be feeling their best.
“It really comes down to the basics,” Dr. Aneja said. “If you touch something and then touch your face, you can get sick. Close contact in crowded or enclosed spaces can also increase your risk.”
Being aware of your surroundings and planning can help you stay one step ahead. If you feel vulnerable or notice someone around you may be sick, wearing a mask can offer an added layer of protection.
Keep it simple: wash, sanitize, repeat
Hand hygiene remains one of the most effective ways to prevent illness while traveling. Washing your hands regularly — or using hand sanitizer when soap and water aren’t available — can help stop germs before they reach your eyes, nose or mouth.
It’s especially important after going through airport security, using shared surfaces or before eating. Making hand hygiene part of your routine while traveling can help reduce your risk and keep small exposures from turning into bigger issues.
Pack a travel health kit (and keep it close)
Dr. Aneja recommends bringing a small travel health kit and keeping it in your carry-on for easy access.
Key items include:
Having these essentials within reach can make a big difference during long travel days or unexpected delays.
Plan ahead, especially for international trips
If your summer plans include traveling abroad, a little extra preparation is worth it. Checking destination-specific guidance ahead of time can help you understand any recommended vaccines, medications or precautions based on where you’re going.
Depending on your destination, that could include insect repellent and protective clothing. In some parts of the world, mosquitoes can carry illnesses, so taking steps to prevent bites isn’t just about comfort — it’s part of staying well.
A quick visit with your doctor can help you prepare with confidence before you go.
Be mindful of heat and hydration
Summer travel often means higher temperatures, which can increase the risk of dehydration and heat-related illness. It’s easy to overlook when you’re having fun, but even mild dehydration can leave you feeling drained. Drinking plenty of water, taking breaks in the shade and planning outdoor activities during cooler parts of the day can help keep your plans on track.
Follow the golden rule of food safety
When traveling internationally, Dr. Aneja shares a simple rule she follows herself:
“Boil it, cook it, peel it — or forget it.”
It’s an easy phrase to remember — and one that can help prevent common stomach-related illnesses that can quickly derail a trip.
In practice, this means eating foods that are fully cooked, choosing fruits you can peel yourself and being cautious with anything that may have been exposed to untreated water. Be cautious with ice, which is often made from tap water and can carry the same risks in certain destinations.
Have a plan, just in case
Even with the best preparation, travel can come with surprises. That’s why it’s a good idea to think ahead about what you would do if you got sick while away from home.
Consider travel insurance, especially if you’re visiting a remote destination, and take a moment to understand what health care options are available where you’re going. Bringing a list of medications or key health information can also be helpful if care is needed.
Enjoy the trip
Staying healthy while traveling doesn’t require a long checklist or complicated routines. A little awareness, thoughtful packing and a few smart habits can help you avoid common travel pitfalls.
Because at the end of the day, vacation is for exploring — not recovering in your hotel room.
