On the latest episode of ‘Prep Talk’, Cari Olson, assistant commissioner of the Bureau of Environmental Surveillance and Policy with the NYC Department of Health and Mental Hygiene, discusses the dangers of extreme heat during the summer months. Ms. Olson shared what precautions New Yorkers should take to beat the heat, and how the city responds to heat emergencies. “My team is responsible for building a foundation of environmental health data and research, that is then used to improve the health of all New Yorkers,” said Cari Olson, assistant commissioner of the Bureau of Environmental Surveillance and Policy with the NYC Department of Health and Mental Hygiene. “For example, we track the health impacts of heat and who is most vulnerable. The triggers for a heat emergency issued by the National Weather Service and Emergency Management are based on data we compiled. As we began collecting data we observed that, once the heat index hits 95 or above, and that is a combination of heat and humidity, there was an exponential increase in deaths from heat in our vulnerable communities.” To prevent heat illness and learn more ways to beat the heat, visit NYC Emergency Management’s Beat the Heat website at NYC.gov/beattheheat, or DOHMH’s Extreme Heat and Your Health page at nyc.gov/site/doh/health/emergency-preparedness/emergencies-extreme-weather-heat.page.
