Severe summer heatwaves in Japan have resulted in a significant decrease in children's outdoor activities, potentially affecting their physical and mental growth. The rise in temperatures, caused by global warming, forces children to stay indoors to avoid the heat, possibly leading to long-term health and developmental issues. Authorities are considering measures to address this environment-induced public health concern that affects the nation's youth.

In Japan, outdoor play is highly valued and considered an essential part of a child's healthy growth and development. The extreme temperatures brought by heatwaves are viewed with concern, as they pose not just instant risks to children's health but potentially long-term developmental issues as well. Schools are adapting by adjusting outdoor play schedules and parents are finding alternative ways to keep kids active indoors.

In the US and EU, similar issues are faced in regions with extreme weather conditions. The decrease in children's outdoor activity due to severe weather is seen as a threat to childhood development and public health. Like Japan, there are attempts to find solutions through adjustments in school schedules and indoor physical activity programs.
