In a recent alert, meteorologists are predicting searing temperatures that could cross 40°C in the Kanto and Tokai regions of Japan during the coming weekend. Residents are urged to be vigilant and take precautions to avoid heatstroke, particularly elderly and those with chronic diseases. The authorities have also appealed to employers to ensure appropriate conditions for their employees, especially those working outdoors.

Heatwaves in Japan often coincide with the peak of the summer season, between July and August. Particularly high temperatures put the health of people, especially the elderly and chronically sick, at risk and can severely impact daily routines and economic activity. Japan's society values care for its senior citizens and puts in place health advisories and cooling centers in extreme weather situations like this, reflecting its focus on communal safety and health.

In the US or EU, heatwave warnings are also issued as public advisories to protect the population, particularly the more vulnerable groups such as the elderly and young children. Measures often include information campaigns about the importance of maintaining hydration and avoiding unnecessary physical exertion. Emergency services are typically on high alert, and temporary shelters or cooling centers may be established in urban areas for those without access to air-conditioning.
