Analysis
A Record-Breaking Heatwave
Japan has experienced a record-breaking heatwave, with temperatures reaching 40 degrees Celsius in some areas. This has led to a surge in heatstroke cases, with over 10,000 people rushed to hospitals in a week. The heat has been particularly severe, with temperatures exceeding 40 C in Gifu and Kyoto prefectures, marking the first such readings in recorded history.
Vulnerable Populations
Older people and young children are more vulnerable to heat-related illnesses. Authorities have urged people to remain in air-conditioned spaces, avoid unnecessary outings, and drink water before feeling thirsty. However, despite these precautions, the number of heatstroke cases continues to rise.
A Global Concern
Heat stress is rising worldwide as human-induced climate change makes heat waves more frequent and severe. Japan experienced record-breaking summer heat for a third consecutive year in 2025. Heat waves and wildfires are also sweeping across parts of Europe, with blazes affecting Spain, France, Italy, Greece, and Cyprus.
Key points
- Over 10,000 people rushed to hospitals for heatstroke in a week, more than double the same period last year.
- Temperatures reached 40 degrees Celsius in some areas, marking the first such readings in recorded history.
- Older people and young children are more vulnerable to heat-related illnesses.
- Authorities have urged people to remain in air-conditioned spaces, avoid unnecessary outings, and drink water before feeling thirsty.
If the heatwave subsides and temperatures return to normal, the number of heatstroke cases is expected to decrease. Additionally, authorities are taking steps to mitigate the effects of the heatwave, such as providing air-conditioned spaces and urging people to stay hydrated.
The heatwave is expected to continue for the foreseeable future, with temperatures remaining high throughout the summer. This poses a significant threat to public health, particularly for vulnerable populations such as older people and young children.
