Bhubaneswar, April 2 (LocalWire): Killing effect of heat “kicks in” when mercury crosses 36.2°C, shows a recent study carried out in the Odisha capital, emphasizing the need for a city-wise temperature threshold to develop customized warning systems.
The study, based on the rise in temperatures and death rates between 2007 and 2014, also showed that the fatalities escalate when it soars beyond 40.5°C.
The research was carried out by a team from the Public Health Foundation of India, the School of Public Health, the Kalinga Institute of Industrial Technology, the Bhubaneshwar centre of the Indian Council of Medical Research and the University of Nottingham in the UK.
“Apart from developing temperature mortality thresholds for different cities, we have also suggested using the traffic-light-like graded method in heat warning advisories,” the Indian Express quoted Ambrish Dutta of PHFI and lead author of the study, as saying.
Co-author and PHFI member Lipika Nanda said that the NDMA has already started asking states to get city-specific temperature thresholds.
“People die at a higher rate on hotter days than on relatively cooler days in summer,” showed the study.
It also showed that a fatal temperature for one region may be normal for other. For instance, heat tolerance level of a Bhubaneshwar resident would be different from the one living in Nagpur.
