The Unseen Risk: Chronic Heat’s Growing Threat to Public Health

This blog post, produced in collaboration with the Asian Development Bank (ADB) following the 1st INSPIRE Health Forum, examines chronic heat—prolonged, daily exposure to high temperatures—as an under‑recognised yet urgent public health challenge. Beyond episodic heatwaves, chronic heat has cumulative impacts on physical health, mental well‑being, and productivity, particularly in tropical regions such as Southeast Asia. The piece highlights the need for data‑driven approaches and integrated solutions, and identifies opportunities to strengthen chronic heat management as part of systemic, cross‑sector resilience.
