Extreme Heat

Extreme Heat is defined as temperatures that are significantly hotter or more humid than commonly occurs in the region during that time of year.

Heat Related Illnesses

Individuals are subject to heat related injuries when their body is unable to cool itself and compensate for heat exposure. Heat related illness is preventable. Individuals should be aware of steps they can take to keep themselves and others safe during extreme heat events.

Air Conditioning & Cooling Centers

Air conditioning is the first line of defense against heat related illness. As such, the Office of Emergency Management coordinates the opening of Cooling Centers during extreme heat events.

Cooling Centers are air condition facilities which residents can patronize in order to stay cool. The Office of Emergency Management also facilitates the transportation of senior citizens and persons with disabilities through the Anne Arundel County Department of Aging. Resident are encouraged to monitor local news outlets regularly in order to obtain information regarding cooling center openings, hours and locations.

Drink Plenty of Fluids

Drink 2-4 glasses of cool fluids each hour. (Warning: Consult with your physician is you have been instructed to limit your fluid intake.)

Replace Salt & Minerals

Sports beverages can replace the salt and minerals you lose in sweat.

Wear Sunscreen & Schedule Outdoor Activities Carefully

Limit outdoor activity to morning and evening hours when the weather is cooler and take regular breaks.

Monitor Those at High Risk

Infants, young children and senior citizens, overweight individuals, those who may easily become dehydrated due to their work or exercise and those with chronic illnesses such as heart disease and high blood pressure.
