The Bureau of Climate and Environmental Health is using a tool developed by the
Centers for Disease Control (CDC) and National Weather Service that forecasts a
major or an extreme heat event in your region. This may put some members of your
community or your patients at risk. To help you prepare, we have provided a collection of
helpful links and information focused on high-risk populations, health hazards associated
with extreme heat, response strategies to extreme heat conditions, and tools to plan and
prepare for future extreme heat events.
What is Extreme Heat?
Extreme heat is a prolonged period of very hot weather, which may include high humidity.
In Massachusetts, a “heat wave” is usually defined as a period of three or more
consecutive days above 90 °F.
Helping Patients and Communities Prepare
Extreme heat can be dangerous and even life-threatening if proper precautions are not
taken. In extreme heat and high humidity, the body must work extra hard to maintain a
normal temperature.
Most heat-related illnesses occur because the victim has been over-exposed to heat or
has over-exercised for his or her age and physical condition. Although anyone can suffer
from a heat-related illness, some people are at greater risk than others. Those at greater
risk include older adults, young children, and those with chronic medical conditions. To
reduce the risks of extreme heat conditions, take the proper safety precautions to protect
your patients and community members.
Sincerely,
The Massachusetts Department of Public Health
