Why Hydration Matters in Japan’s Summer

Japan’s summer, from June to September, brings not only beautiful festivals and fireworks but also dangerously high heat and humidity. Dehydration and loss of minerals like sodium can quickly lead to heatstroke, especially during outdoor activities or crowded events.

Key Points:

• Sweating causes rapid loss of water and electrolytes.

• Children, women, and seniors are especially vulnerable.

• Symptoms of heatstroke include dizziness, headache, nausea, and, in severe cases, loss of consciousness.

Preventing heatstroke in Japan starts with drinking the right fluids—regularly, even before you feel thirsty.

Key Symptoms and Prevention of Heatstroke

Recognize the Signs:

• Mild: Dizziness, muscle cramps, nausea, excessive sweating

• Moderate: Headache, vomiting, severe fatigue

• Severe: Confusion, high fever, unconsciousness

Prevention Tips:

• Drink water and sports drinks with electrolytes frequently.

• Wear light, breathable clothing and take breaks in the shade.

• Supplement salt lost through sweat with drinks or snacks.
