To bring relief to patients amid rising heat in the city, the North City Corporation has started recording temperature and humidity levels at the Primary Health Centres (PHCs) during peak hours. Ten PHCs have been identified so far, with work already started at two of these health facilities. After collecting the temperatures for up to a week, the selected buildings will be coated with heat-reflective paint. The intervention is expected to lower indoor temperatures by up to 15 degrees Celsius, corporation officials said.
