"Temperature" is important as a condition that causes heat stroke, but in Japan's hot and humid environment, the risk of heat stroke cannot be evaluated based on temperature alone. The heat index (WBGT) issued by the Ministry of the Environment focuses on the exchange of heat (heat balance) between people and the outside air. It is especially used to prevent heatstroke during work and exercise.

Please check the heat index as a guideline for heatstroke prevention.

A heat stroke alert will be issued on days when the risk of heat stroke is expected to be extremely high (heat index of 33 or higher).

Please check information about heat stroke frequently, such as Heat stroke warning information別ウィンドウで開く (open in new window) on TV and Ministry of the Environment.

In addition, from July 1, 2023, if a heat stroke warning alert is issued, we will notify you via the disaster prevention administrative radio at 10;00 am on the day it was issued.

Heatstroke is a state in which heat builds up in the body due to an imbalance of water and salt in the body caused by being in a hot environment, and the body's temperature control function does not work well.

It is predicted that the temperature will rise from now on and the severe heat will continue.

Elderly people, children, and people with disabilities are particularly susceptible to heat stroke, so special attention is required.

Learn appropriate preventive measures to prevent heatstroke. Also, make sure to eat well and rest well on a daily basis to build your body.
