How heat affects the elderly and how you can help


Gail Wilcox, ombudsman supervisor at South Western Oklahoma Development Authority Area Agency on Aging (SWODA AAA), advises that the elderly are more likely to experience the effects of hot weather than younger adults. Physically, the elderly cannot adjust to significant changes in temperature as well as younger adults can. That combined with the effects of prescription drugs; which also reduce the body’s ability to adjust to temperature changes, may exacerbate the side effects they may experience. Many medications the elderly take may cause dehydration or affect the ability of their heart, blood vessels or sweat glands. This in turn would affect their overall ability to respond to high temperatures.

When the body’s temperature hits 104 degrees Fahrenheit, heat stroke sets in and can cause permanent brain damage or even death. Signs that someone is suffering from heat stroke may include the following: A strong, rapid pulse; Lack of sweating; Dry, flushed skin; Faintness or staggering; and mental status changes such as: confusion, combativeness, disorientation or even coma.

Another concern concerning high body temperatures would be heat exhaustion. Heat exhaustion can progress to heat stroke when the body fails to regulate its own temperature. The affected individual becomes confused, lethargic and may have a seizure. Their skin stops sweating and their body temperature may exceed 106 degrees Fahrenheit. Symptoms of heat exhaustion include the following: Thirst, Weakness, Profuse sweating, Nausea and/or vomiting, and Headache or lightheadedness.
