From the Harford County Health Department:
Bel Air, MD – June 16, 2015 – With rising temperatures and humidity bringing heat index numbers into the 90’s, summer apparently has arrived a week early. As schools recess for the summer, vacation season begins for many while both work and play around the house translates to more time exposed to indoor as well as outdoor heat. The Harford County Health Department warns residents to take precautions in hot weather against serious and potentially deadly heat illnesses.
The first reported cases of heat-related deaths in Maryland occurred almost this time a year ago and Harford County Health Officer Susan Kelly reminds the public about the seriousness of heat illnesses. She advises residents to prepare for steadily climbing temperatures and a rising heat index that will only increase over the next few months.
Ms. Kelly states, “Individuals of all ages need to be cautious when vigorously working or playing outdoors or even when exposed for extended periods of time to hot indoor environments. Prolonged exposure to hot and humid weather conditions can result in potentially life-threatening heat-related illnesses and injuries. Persons who are exposed to excessive heat for any length of time, whether indoors or out-of-doors, must know risks and be exceptionally careful.”
Heat illness takes many forms, including heat fatigue, heat syncope (sudden dizziness after exercising in the heat), heat cramps, heat exhaustion or the most serious, heat stroke. Heat stroke, is an advanced form of heat stress that occurs when the body is overwhelmed by heat and unable to control its temperature. Someone with a body temperature above 104 degrees is likely suffering from heat stroke and may have symptoms of confusion, combativeness, strong rapid pulse, lack of sweating, dry flushed skin, faintness, staggering, possible delirium or coma. Seek immediate medical attention for a person with any of these symptoms, especially an older adult.
Basic strategies are key to preventing heat illness and focus on limiting exposure to excessive heat, limiting activity, dressing accordingly in lighter weight clothing, and staying hydrated by drinking more noncaffeinated, non-alcoholic fluids than usual. The risk for heat illness is a combination of the outside temperature along with the general health and lifestyle of the individual. Health-related factors that may increase risk include:
–The inability to perspire, caused by medications such as diuretics, sedatives, tranquilizers and certain heart and blood pressure drugs.
–Taking several drugs for various conditions. It is important, however, to continue to take prescribed medication and discuss possible problems with a physician.
–Being considerably overweight or underweight
–Drinking alcoholic beverages
–Age-related changes to the skin such as poor blood circulation and inefficient sweat glands
–Heart, lung and kidney diseases, as well as any illness that causes general weakness or fever
–High blood pressure or other conditions that require changes in diet. For example, people on salt restricted diets may be at an increased risk. Salt pills should not be used without first consulting a doctor.
Lifestyle factors that also can increase risk include extremely hot living accommodations without cooling and/or adequate ventilation, lack of transportation, visiting overcrowded places and not understanding how to respond to changing weather conditions. Individuals at special risk should stay indoors on particularly hot and humid days, especially when there is an air pollution alert in effect. People without fans or air conditioners should go to places such as shopping malls, movie theaters, libraries or cooling centers.
Ms. Kelly also encourages everyone to remember to pay attention to family members, co-workers, friends, neighbors, and even pets. “Make sure to take necessary precautions, especially if they are young, elderly, or ill.”
