Record-setting heatwaves are impacting travel plans this summer, prompting experts to urge extra caution and preparation for those with upcoming trips. Extreme temperatures pose significant health risks, and many travelers may not be accustomed to such conditions.
"The biggest mistake people make is underestimating the power of the sun," said Melissa Yeager, senior news editor at Lonely Planet. "You may step outside and think, ‘Oh, this isn’t so bad.’ But, the heat can really creep up on you, especially if you are spending a lot of time outdoors and you haven’t prepared."
Hydration and Activity Planning
Experts emphasize the importance of staying hydrated, recommending travelers drink plenty of water throughout the day and carry a water bottle. Avoiding dehydrating beverages such as alcohol and coffee is advised, and for those who do consume them, drinking extra water to compensate is crucial. Hydration boosters and electrolytes may also be necessary, as water alone might not suffice in extreme heat.
"Water alone might not be enough when facing the extreme temperatures of a heat wave — you also need to replace the electrolytes that you’re losing," said Justin Chapman, a travel expert at Go2Africa. "Without minerals like sodium, potassium and magnesium that deliver hydration to your cells, your body can’t absorb the proper hydration that it needs."
Travelers are also encouraged to plan itineraries around the heat, scheduling outdoor activities for cooler parts of the day, such as early morning or evening. Midday hours, typically the hottest, should be reserved for indoor activities like visiting museums, art galleries, or enjoying extended lunches. Huw Owen, co-founder of Vacation-Planning Marketplace TravelLocal, suggests using the heat as an opportunity to engage in cultural immersion.
Managing Expectations and Clothing
Experts also advise travelers to manage their expectations, encouraging them to embrace the concept of "dolce far niente," the joy of doing nothing, rather than feeling pressured to see every attraction. This is particularly important for parents, who are reminded that children are often content simply being in a new place with their families.
Choosing appropriate clothing is another key consideration. While it may be tempting to wear minimal clothing, covering up with light, breathable fabrics like cotton and linen can help keep the body cooler than exposing skin to direct sunlight. Light colors are also recommended.
Prioritizing Health Signals and Sun Protection
Paying attention to one's body is paramount, especially for individuals with chronic health conditions. Dr. Gregory Katz, a cardiologist at NYU Grossman School of Medicine, stressed the importance of not pushing through unusual sensations and being honest about one's health risks. Travelers should ensure they pack and take any necessary medications consistently.
Sunscreen application and reapplication are critical. Experts recommend using a high-SPF sunscreen and reapplying at least every two hours, as sunburn can occur even on cloudy or windy days. Limiting direct sun exposure, especially during peak heat hours, and using methods like damp towels on the head and neck can help prevent overheating.
Chapman suggests a "backward beach day," visiting the beach in the late afternoon when temperatures are lower, allowing for some sun exposure while minimizing risk.
