With temperatures staying high this summer, we all need to be aware of the increased risk for heat stroke and other heat-related illnesses. As people age, they are at an increased risk – and those with chronic health issues are even more at risk – according to the U.S. National Institute on Aging (NIA).

Heat fatigue, heat-related dizziness, heat cramps, heat exhaustion and heat stroke are all forms of hyperthermia. The condition occurs when the body is overwhelmed by heat and is unable to control its temperature. Those who lack access to air conditioning or transportation, who can't move around, wear too much clothing or visit crowded places may be more vulnerable.

Other factors that increase hyperthermia risk include:

•  Dehydration.
•  Poor blood circulation.
•  Less sweat production due to aging.
•  Use of multiple medications.
•  High blood pressure or other health conditions that require a reduced-salt diet.
•  Heart, lung and kidney diseases or other conditions that cause general weakness or fever.
•  Being very overweight or underweight.
•  Drinking alcohol.

When temperatures, air pollution and humidity spike, older people with chronic health issues like heart disease and diabetes should stay indoors. Those who don't have air conditioning should go to a mall, senior center, library or other cool location.

The NIA reminds us to recognize the warning signs:

•  Fever (generally above 104 degrees Fahrenheit).
•  Confusion or combativeness.
•  Strong, rapid pulse.
•  Dry, flushed skin.
•  Lack of sweating.
•  Feeling faint.
•  Staggering.
•  Coma.

Anyone who may be suffering from a heat-related illness should be taken to a shady or air-conditioned spot and told to lie down. A cold, wet cloth should be applied to the wrists, neck, armpits and groin to help cool the blood. If the person can swallow, he or she should be given nonalcoholic fluids like water or apple juice.
