Knowing the changes in temperature and humidity that day, as well as the indoor temperature and humidity conditions, is very important for preventing heatstroke. Try to find out what kind of environment you are in right now.

Drink plenty of water even if you're not thirsty. We recommend carrying a drink with you so you can stay hydrated when you go out. Aim to drink at least 1.2 liters of water per day.

If you press your nails and it takes more than 3 seconds for the color to return from white to pink, you may be dehydrated.

Hydrate immediately.

If your physical strength is low, your risk of heatstroke increases. People who tend to be sleep deprived need to be especially careful. If you feel tired, try to take a rest in a cool place. During the summer, when it's easy to get tired, many people lose their appetite and skip meals, or are unable to eat much. Make sure to eat a nutritionally balanced diet.
