Learn the Signs of Heat Emergencies

While many people look forward to enjoying the outdoors in summer, the hot summer months can also pose health and safety risks.

Heat emergencies are health emergencies caused by exposure to hot weather and sun. Many people know them as heat stroke and heat exhaustion.

Children and older adults are more vulnerable to heat emergencies.

Children often do not recognize the warning signs of heat emergencies, and young children don’t sweat as much as adults, putting them at higher risk for issues.

Older adults tend not to adjust well to sudden increases in temperature. Seniors may also have chronic medical conditions that change normal body response to heat, and they are more likely to take prescription medicines that affect the body’s ability to control temperature.

From 2004–2018, an average of 702 heat-related deaths occurred in the United States each year.

Time is of the essence when someone is experiencing a heat emergency.
