Rising global temperatures are increasing reliance on air‑conditioning, a technology shown to significantly reduce heat‑related deaths but burdened by environmental and energy costs. A historic 1903 cooling system at Belfast’s Royal Victoria Hospital illustrates early efforts to use controlled indoor environments to protect patients, a need now intensified by modern heat waves. Studies show strong survival benefits from air‑conditioned medical facilities, while cities worldwide are developing cooling shelters, public cold spaces, and interactive maps to help residents escape extreme heat. Despite concerns over energy use and refrigerant emissions, experts warn that passive cooling is no longer sufficient in many regions, pushing governments to invest heavily in cooling infrastructure for hospitals and public spaces. The preserved early system in Belfast stands as a reminder of the critical role cooling plays in safeguarding health amid accelerating climate risks.
