As Americans prepare for the long-awaited July Fourth weekend, a mix of patriotism, travel, and sun-soaked adventures are on the horizon. While families pack for beach vacations and backyard barbecues, the Centers for Disease Control and Prevention (CDC) and other health organizations are offering essential travel health advice. Whether you’re heading out of town or simply planning a staycation, it’s crucial to consider the potential health risks and best safety practices, from sunscreen use to preventing measles outbreaks.

Traveling across the U.S. this summer has its fair share of risks, and among the top concerns this year is the measles outbreak. As of June 2025, the U.S. has seen an uptick in measles cases, and travelers need to be aware of vaccination recommendations. The CDC reports that measles cases have reached their highest levels in recent years, posing a heightened risk for those who have not been vaccinated. In particular, children under five and adults without a complete vaccination history are the most vulnerable.

For travelers planning to visit destinations with a high rate of infection, the CDC strongly urges individuals to verify their vaccination status before departure. Many states, particularly in the Midwest and Southeast, have reported increased numbers of measles outbreaks. Those considering international travel are also at risk, as the disease continues to spread in various parts of Europe, Africa, and Asia. For these reasons, it is important to consult with healthcare providers prior to traveling to ensure that measles vaccinations are up to date.

The CDC also highlights the importance of carrying proof of vaccination during international travel. A single dose of the measles-mumps-rubella (MMR) vaccine is recommended for travelers aged 12 months and older. For those planning to visit countries where the risk of measles is higher, it may be advisable to receive an additional dose.

With sunny weather expected across the country, sunscreen remains a vital part of healthy travel preparations. The CDC has long recommended broad-spectrum sunscreen with an SPF of 30 or higher as an effective way to protect against skin cancer and sunburns. However, with a range of options on the market, choosing the right sunscreen for your needs can be confusing. The main distinction lies between chemical and mineral sunscreens.

Chemical sunscreens contain active ingredients like avobenzone, octocrylene, or oxybenzone, which absorb UV rays. These are often favored for their lightweight feel and transparency when applied to the skin. In contrast, mineral sunscreens use physical blockers like zinc oxide or titanium dioxide, which sit on top of the skin and reflect UV rays. While these formulas tend to be thicker and visible upon application, they are often recommended for those with sensitive skin or conditions like rosacea or acne.

For travelers, it’s essential to remember to reapply sunscreen every two hours, especially if swimming or sweating. The American Academy of Dermatology also recommends a higher SPF rating for those with fair skin or those traveling to sunny, high-altitude locations where UV rays are more intense. Along with sunscreen, wearing protective clothing, such as hats and sunglasses, and seeking shade during peak sun hours (10 a.m. to 4 p.m.) can help reduce exposure.

Beyond sunscreen, travelers may want to consider another safety item on their packing list: a carbon monoxide (CO) detector. While the risk of carbon monoxide poisoning is relatively low, it is not nonexistent. The CDC notes that the gas is especially dangerous in poorly ventilated spaces, like cabins, apartments, or older rental homes. Kathryn Gillett, a Wichita traveler, shared her personal experience of carrying a small, battery-powered CO detector during her stays in international destinations like Buenos Aires.

The device, which weighs just 10 ounces and is about the size of two stacked smartphones, can be purchased for as little as $20. Experts recommend having one with you, especially when traveling to remote locations where air quality might not be well-monitored. While the risk is minimal, a portable CO detector could provide peace of mind, ensuring that travelers enjoy their vacation without worry.

For those traveling with an eye on both health and budget, nutrition is another factor to consider. Often, healthy eating while traveling can feel like an expensive endeavor, especially when resorting to fast food or dining at tourist-heavy areas. However, nutritious and affordable options are available. The CDC emphasizes the importance of incorporating beans, peas, and lentils, collectively known as pulses, into daily meals. These foods are not only high in protein and fiber, but they also contribute to gut health and help manage blood sugar levels.

When traveling, pulses are versatile, portable, and easy to incorporate into meals. Whether purchasing canned beans or packing dried lentils, travelers can enjoy a healthy, filling snack that doesn’t break the bank. Plus, pulses have a low carbon footprint, making them an environmentally friendly food choice.

As the July Fourth weekend approaches, travelers are encouraged to prioritize their health by taking necessary precautions against the risks associated with sun exposure, vaccine-preventable diseases like measles, and environmental hazards like carbon monoxide. Ensuring that vaccinations are up to date, packing proper sunscreen, and carrying health essentials can all contribute to a smooth and worry-free travel experience. By following these recommendations, travelers can enjoy a safe, healthy, and fun-filled holiday season with peace of mind.

For those who experience difficulties in dealing with the physical or emotional challenges of travel, it’s also important to seek help, whether through medical professionals, counselors, or support networks. Enjoying your travels starts with taking care of yourself and others around you, making health and safety your top priority.
