Rising seasonal temperatures in Japan have led to an influx of heatstroke cases, particularly impacting the younger generation. The unusual weather phenomenon, known as 'Valley-Type Heat Shock', causes sudden and extreme changes in temperature, posing serious health risks. Despite a common misconception that only the elderly are vulnerable to heatstroke, recent statistics show a surge in incidents among the younger populace, prompting authorities to alert the public and encourage precautions among all age groups.

In Japan, heatstroke during summer months is critical due to high humidity and intense heat. It's thus a major social issue, especially with increasing climate change impacts. Japanese people pay great attention to weather updates and adopt preventive measures such as staying hydrated, wearing light clothing, and avoiding the sun during peak hours. The Japanese government manages public awareness campaigns routinely, emphasizing care for all, not just the older population.

In the US and EU, heat stroke is similarly considered a serious health concern. This is particularly true in parts of the US with intense summer heat, such as the southwest regions. The approach to prevention and awareness is akin to the one in Japan: regular weather updates, awareness campaigns, and suggesting preventive measures. However, in Europe, where the summer heat is typically less severe compared to Japan and the US, the focus often lies on specific groups such as the elderly or outdoor workers.
