Extreme Heat & Air Quality Alert
Health Advisory

– Please distribute widely –

Heat wave throughout New England

High heat and humidity for three days or more make for hazardous conditions, especially when experienced by people who are most susceptible to heat-related illnesses. Heat-related illnesses include heat cramps, heat syncope, heat exhaustion and heat stroke, and result from the body’s failure to thermoregulate and maintain normal core body temperature.

Getting susceptible people to air-conditioned space is the single most important strategy to prevent heat illness. Those who are especially susceptible include the young, the elderly, pregnant women, and people with chronic or serious health conditions.
