As we age, our ability to adequately respond to summer heat can become a serious problem. Older people are at significant increased risk of heat-related illnesses, known collectively as hyperthermia, during the summer months. Hyperthermia can include heat stroke, heat edema (swelling in your ankles and feet when you get hot), heat syncope (sudden dizziness after exercising in the heat), heat cramps, and heat exhaustion.

Heat stroke is a severe form of hyperthermia that occurs when the body is overwhelmed by heat and unable to control its temperature. Someone with a body temperature above 104 degrees Fahrenheit is likely suffering from heat stroke. Symptoms include fainting; a change in behavior (confusion, combativeness, staggering, possible delirium or coma); dry, flushed skin and a strong, rapid pulse; and lack of sweating. Seek immediate medical attention for a person with any of these symptoms, especially an older adult.

If you suspect that someone is suffering from a heat-related illness:

• Call 911 if you suspect heat stroke.
• Get the person out of the heat and into a shady, air-conditioned or other cool place. Urge them to lie down.
• If the person can swallow safely, offer fluids such as water and fruit or vegetable juices, but not alcohol or caffeine.
• Apply a cold, wet cloth to the wrists, neck, armpits, and groin. These are places where blood passes close to the surface of the skin, and a cold cloth can help cool the blood.
• Encourage the person to shower, bathe, or sponge off with cool water if it is safe to do so.

If you are having a hard time paying for home cooling and heating costs, there are some resources that might help. Contact the National Energy Assistance Referral service, your local Area Agency on Aging, senior center, or social service agency.
