Delhi Traffic Police are trialing battery-operated air-conditioned cooling helmets for officers stationed at high-congestion points to combat a severe heatwave.
The deployment aims to protect personnel from heat-related illnesses while they manage traffic in extreme conditions. This initiative addresses the physical toll on officers who remain stationary for hours under direct sunlight during peak summer months.
Officers at locations such as the Teen Murti Roundabout are utilizing the new gear, which includes portable fans. Some reports indicate that the trial extends beyond the capital to include the Saharanpur Police in Uttar Pradesh [1, 2].
The technology is designed to significantly reduce the thermal load on the wearer. According to available data, these cooling helmets can lower head temperature by eight °C to 12 °C [1]. Each unit operates on a battery charge that lasts between four and five hours [3].
The rollout coincides with a period of extreme weather and high energy stress. Maximum ambient temperatures during the heatwave have been reported between 43 °C and 45 °C [2, 3]. The intensity of the weather has also impacted the city's infrastructure, with peak power demand in Delhi reaching 8,439 MW [4].
By integrating active cooling into standard equipment, the police department seeks to maintain operational efficiency without compromising officer health. The pilot program will monitor how the helmets perform in real-world urban environments where humidity, and pollution often exacerbate the effects of high temperatures.

The adoption of wearable cooling technology reflects an increasing need for climate-adaptive labor protections as urban heat islands intensify. By shifting from passive shade to active cooling, city administrations are acknowledging that traditional uniforms are insufficient for the rising temperature peaks seen in South Asian summers.
