Stay Comfortable This Summer in Japan: Heatstroke Prevention Tips
Japan's summers, especially in the Kanto region, are known for their high temperatures and humidity. This sticky heat can be more draining than you might expect. The risk of heatstroke isn't limited to the outdoors; it can happen indoors too. To ensure a comfortable and safe trip, keep the following tips in mind.
1. Frequent Hydration and Salt Intake
It's crucial to consciously and regularly drink water, even if you don't feel thirsty. You can find a wide variety of drinks not just at cafes and restaurants, but also at vending machines and convenience stores across the city.
When you sweat a lot, your body loses not only water but also salt. Sports drinks and oral rehydration solutions are recommended as they efficiently replenish both. Also, make use of convenient salt candies or salt tablets.
2. Strategies to Avoid the Heat
Choose lightweight, breathable clothing made from moisture-wicking and quick-drying materials for comfort.
During the hottest parts of the day (roughly 10 AM to 4 PM), try to avoid strenuous outdoor activities. Instead, plan to cool off at indoor attractions or shopping malls.
When you're outside, simply making an effort to walk in the shade, such as under trees in parks or in the shadow of buildings, can significantly reduce the strain on your body.
3. Why the Umbrellas on Sunny Days? Japan's "Parasol" Culture
If you're a visitor from overseas, you might wonder why many Japanese people carry umbrellas on sunny days. These aren't for rain; they're called "higasa" (日傘), which are items designed to protect your skin and body from the strong sunlight.
The summer sun in Japan is incredibly intense, and parasols are highly effective not only for UV protection but also for preventing heatstroke. Using a parasol can block direct sunlight and is said to lower your perceived temperature by several degrees. You'll find a wide range of stylish designs, including options for men, compact foldable types, and those with excellent UV-cut features. We encourage you to get one locally and experience how smartly and comfortably you can enjoy the Japanese summer!

5. Pay Attention to Changes in Your Condition
If you experience symptoms like dizziness, lightheadedness, fatigue, headache, or nausea, these could be signs of heatstroke. Immediately move to a cool place, cool your body, and rest.
If your symptoms don't improve, or if you show signs of severe heatstroke such as confusion, don't hesitate to ask for help from those around you or seek medical attention at the nearest clinic or hospital. Pushing yourself too hard is dangerous.
