Kanto Smart Living Cooperative Issues Heatstroke Prevention Guidelines Amid Rising Summer Risks in Japan
Prevention is key—stay cool, stay hydrated, and watch over the vulnerable. Even cloudy days carry heatstroke risks,” Kanto Smart Living Cooperative states.

TOKYO, JAPAN (MERXWIRE) – As Japan enters the interlaced season of hot summer and rainy season, the meteorological authorities announced that the temperature in some areas has exceeded the 38°C mark. The combination of high temperature and high humidity has dramatically increased the risk of heat stroke. Kanto Smart Living Cooperative, an organization dedicated to family life and daily health care, released “5 Practical Strategies for Dealing with Heat Stroke”, calling on Japanese people and overseas tourists to strengthen their awareness of heatstroke prevention, especially paying attention to the health of high-risk groups such as children and older people.
Kanto Smart Living Cooperative puts forward five suggestions for heatstroke prevention, including: “Use air conditioning to cool down,” “Regularly replenish water and salt,” “Take care of high-risk groups,” “Pay attention to heatstroke at night,” and “Adjust activities according to the heatstroke index.” The association said that even if the weather is cloudy and there is no scorching sun, heat stroke may occur due to high humidity, so everyone should develop the habit of regular hydration and rest.
Children are a potential high-risk group for heat stroke because they cannot clearly express physical discomfort. Parents are advised to closely monitor their children for any abnormal phenomena, such as blushing, excessive sweating, or fatigue. They should immediately move their children to a cool place to rest and provide them with cold drinks, ice packs, and cooling towels to help them cool down. It is recommended to use water bottles with ice cubes instead of frozen water bottles, and you can add water to continue using them after drinking.
Similarly, older people are prone to ignore the threat of high temperatures due to their decreased metabolism and intense awareness of energy conservation. According to statistics in 2021, nearly 60% of those who were sent to the hospital for heat stroke were over 65 years old. The association calls on family members to proactively contact their elders at home and remind them to turn on the air conditioner and drink water regularly, such as drinking water when getting up, at 10 a.m., after lunch, and before going to bed, to avoid the dangerous behavior of “drinking water only when thirsty.”

The risk of heat stroke at night should not be ignored. When the nighttime temperature exceeds 25°C, even without direct sunlight, people may still experience heat stroke due to dehydration and high temperatures during sleep. Experts recommend keeping the air conditioner running, having room-temperature drinking water by the bed, and drinking a glass of water before going to bed as necessary preventive measures.
For the recent large number of overseas tourists traveling to Japan, Kanto Smart Living Cooperative also reminds us explicitly that tourists from relatively mild climates often lack adaptability to the high temperatures and humidity changes in Japan during the summer and are more likely to ignore the risk of heat stroke. Travelers should carry water bottles and cooling supplies with them during their trips, avoid prolonged exposure to the outdoors during midday hours, and monitor their own and their companions’ physical conditions. If they experience symptoms such as dizziness or nausea, they should rest, replenish their water, and seek medical attention if necessary. Only by staying healthy during the trip can you fully enjoy the beauty of Japan.
People can check the daily warning level through the heat stroke index website provided by NHK. The system is graded based on temperature, humidity, and sunshine. It is recommended that outdoor activities should be avoided in principle when the index exceeds 31. Kanto Smart Living Cooperative emphasizes that prevention is better than cure, and all people should be vigilant, adjust their daily routines and lifestyles, and meet the challenges of midsummer safely and healthily.
