How many can you get right? Check your general knowledge with a heatstroke trivia and fun facts quiz.

28℃

Japan’s Ministry of the Environment and other authorities recommend maintaining an indoor temperature of 28°C as an effective measure to prevent heatstroke. Setting it too low may affect your health, so aim for around 28°C. When using an air conditioner, make sure the room doesn’t exceed 28°C. If you’re sensitive to cold air, try keeping the room at the right temperature by, for example, wearing a blanket over your clothes.

armpits, neck, and groin

There are large blood vessels under the armpits, in the neck, and in the groin. Cooling these areas can lower body temperature efficiently. If you develop heatstroke, it’s recommended to focus on cooling areas where major blood vessels run close to the surface of the body. Try cooling the neck, armpits, and groin first.

Drink fluids only after you feel thirsty following exercise.

Because drinking fluids only after you feel thirsty is too late, it’s important to hydrate regularly before thirst sets in to prevent heatstroke. In particular, unlike people who exercise regularly, those who don’t are at higher risk of heatstroke if they push themselves too hard, so please be careful.

obese type

It is said that people with an obese body type have a lot of body fat, which traps heat inside the body and makes it harder to release, making them more prone to heatstroke. Therefore, people with obesity need to be especially careful about hydration and health management during hot periods. Be cautious, as having a lot of subcutaneous fat makes it difficult for heat to escape from the body.

28 degrees

In general, it is said that the risk of heatstroke increases when the temperature exceeds 28°C (82°F). The danger is even greater when humidity is high. Be sure to hydrate frequently and take breaks when going out or exercising. Besides temperature, humidity and wind also play a role, so pay extra attention on humid days or when there is little to no wind.

black coffee

Black coffee contains a lot of caffeine and promotes diuresis, making the body lose fluids easily, so it is not suitable for preventing heatstroke. Sports drinks and barley tea are suitable for hydration. Barley tea is caffeine-free and contains minerals, making it one of the drinks suitable for heatstroke prevention.

watermelon

Watermelon has a high water content and contains minerals such as potassium, making it suitable for preventing heatstroke. Because it also contains minerals, it’s an ideal food for heatstroke prevention. It also contains salt, which helps with recovery from fatigue, so it’s especially recommended in summer.
