Bring on the Heat

Vietnam is hot!

Literally!

The temperature remains one of the major inconveniences of the country, and its unpredictability continues to pose challenges. While southern Vietnam maintains a hot climate all year round, the northern regions experience a significant variety in weather (think sweltering summers and chilly winters with occasional rain). To combat the heat, it is advisable to drink at least 2 liters (or half a gallon) of water on a relaxed summer day. Those from cooler climates, whose bodies may not be accustomed to high temperatures, might need to hydrate even more depending on their activity levels each day.

In the winter months, northern Vietnam's drier and cooler climate may be easier on your body. However, visitors should be cautious when traveling to Quang Binh, home to the world's largest caves! The central coastal provinces are widely regarded as the hottest region in Vietnam, characterized by a lack of moisture and bright sunshine throughout the year. Avoid biking through this area during July unless you are ready for an adventurous challenge.

Overall, it’s essential to listen to what your body is telling you and take care of it!

A good indicator of hydration is the color of your urine. A light yellow hue typically signals adequate hydration, assuming you are in good health. Clear urine can indicate excessive water intake, while dark yellow suggests your body needs more fluids. Adding a pinch of salt to your water can help slow the dehydration process, as it allows your body to retain fluids more efficiently.

Make sure to drink significantly more than you routinely would back home in temperate Switzerland, especially after exercising. A standard three-mile vigorous hike can deplete your body by about two-fifths of a bottle of water. Remember to drink slowly, as consuming large quantities of water at once can result in disorientation and discomfort, especially in a country known for its culinary delights.

Avoid alcoholic beverages and coffee during outdoor activities since these can lead to faster dehydration. However, if you wish to embrace the heat, consider enjoying a cup of the local strong coffee before embarking on an evening 5,000 meter run; this combination might help you shed some pounds. But be cautious, as the extreme heat can turn a good workout into a risk for heat exhaustion. Always replenish with fluids and calories afterward, and remember to heed your body’s signals!

One benefit of the sweltering sun is that clothes usually dry quickly outdoors. Locals often hang their laundry outside, taking advantage of the natural heat and sunlight to achieve that fresh scent. If you prefer a dryer, be prepared to search extensively for one, as they are not common.

It’s wise to avoid prolonged exposure to the sun without wearing a hat. The risk of headaches and, worse yet, lengthy recovery periods from heat-related illnesses is high. The combination of harsh sunlight, humid air, and pollution is detrimental to well-being. Avoid drastic temperature changes; for example, if you are sweating profusely, try not to let the rain hit you. Find shelter to cool down and consider waiting out the rain. Local cafes can serve as great respite spots.

While many locals prefer to avoid the sun, foreigners often seek a tan. If you want to enjoy being in the sun, exercise caution as UV rays can be harmful. Use sunscreen and avoid extended sun exposure in minimal clothing. Remember to wear headgear to shield yourself from the sun, which can be easily found at a variety of local shops. Comfortable shoes are essential, especially if you prefer footwear with breathable materials, as it's important for your feet to remain dry.

Armed with this knowledge about Vietnam’s heat, you’ll find it more manageable as an outsider. Prepare yourself for the journey, and you'll be able to enjoy the sunny weather while staying healthy and hydrated!
