These guidelines on Emergency Cooling for Severe Heat-Related Illnesses are prepared under National Programme on Climate Change and Human Health (NPCCHH), National Centre for Disease Control (NCDC), MoHFW. Aligned with the programme’s goal, the guidelines emphasize the significance of rapid and active cooling in addressing severe heat-related illnesses. With a specific focus on various body cooling methods, the guidelines are envisioned to support the incorporation of this approach into emergency care throughout the healthcare system, adapting to the increasing climate change and extreme heat events.
