Extreme Heat
Heat-related illness generally results from the body’s inability to cool itself. When the body’s temperature control systems of perspiration and circulation are overloaded, or when the body cannot restore fluids and salt lost through sweating, the temperature of the body’s inner core begins to rise. This rise may lead to heat-related illness.
Often, heat-related illness is related to high heat index readings.
Seniors, children up to four years of age, people with physical disabilities or behavioral health problems, and those on certain medications or drugs, are particularly at risk for heat reactions, especially during extremely hot weather.
Infants and children up to four years of age are at risk for heat-related illness because their small bodies cannot regulate body heat as well as older children or adults. They also may not be able to escape hot places; every summer there are tragic reports of young children who die of heatstroke because they are left in locked vehicles for a short time.
However, even young and healthy individuals can succumb to heat if they participate in strenuous physical activities during hot weather.
How can heat-related illness be prevented?
Air conditioning is the best defense against extreme heat, even if for just a few hours a day. To reduce the risk, consider visiting a shopping mall, or a public library or another public building with cool air for a few hours. Taking a cool shower or bath can also provide some relief.
Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness.
