The Lebanon Fire and Emergency Management Department would like Lebanon residents to be aware of the following information related to the potential effects of extreme temperatures. There are a number of risks associated with exposure to heat. Please see the below information and, as always, if you have questions please contact the Lebanon Fire Department at 603-448-8810.

Heat Index and Associated Health Risks

The heat index is defined by the National Weather Service as a measure of how hot it really feels when relative humidity is factored with the actual air temperature (see chart below).

As the heat index rises, so do the health risks. This is especially true in the following vulnerable populations: 
  • Infants and small children under age 3 
  • Pregnant women 
  • Adults age 65 or older 
  • Individuals with drug or alcohol addictions 
  • People working under extreme conditions
  • People with medical conditions (e.g. heart disease, diabetes, high blood pressure)
