Amid the ongoing summer period in Japan, the populace faces an increasing threat of “nighttime heatstroke.” Its danger lurks due to people's unawareness, with many mistakenly thinking that the risk of heatstroke drops significantly after sunset. The Japanese health authorities are stepping up measures to inform and guide the public about necessary precautions and responsive strategies.

In Japan, the high risk of heatstroke, especially during nighttime, stems from the country's humid summers. People are very concerned about this issue, as it directly impacts their health and daily lives. Public awareness campaigns and early-warning measures initiated by government bodies stand testament to the importance placed on this matter.

In the U.S or E.U, similar issues are also prevalent, primarily in regions with hot climates. However, approaches to combat heatstroke differ slightly, with more focus on technological solutions, such as air conditioning and climate control systems, along with public health guidelines. The issue of nighttime heatstroke may not be as highlighted, due to cooler night-time temperatures in most regions.
