Seniors and Heat: Cool It!

Tuesday, July 19th, 2011

Every summer, heat waves plague the Northeast. While usually brief, these weather patterns can be dangerous for seniors. Once heat creeps into the house and settles in, it can prove difficult to get it back out, especially the humid air that Maine is so famous for. It can wrap around you like a blanket.

For most of us, high temperatures are simply uncomfortable and cause occasional sleepless nights. But seniors have added concerns, as they can be at higher risk for heat-related health problems. This is particularly true for those who have heart, lung or kidney disease.

Heat-related illnesses such as heat exhaustion and heat stroke are not to be taken lightly.

Symptoms of heat exhaustion include thirst, confusion, weakness, dizziness and nausea.

A cooling dip in a pool or pond can help lower your body temperature.

If you experience any of these symptoms, take them seriously. Immediately shower or bathe, if you are feeling steady enough to do so. If not, sponge off with cool water, drink cool water or juice and lie down to rest, preferably in a cool place. If you are outside in the sun, find shelter immediately. If you are not better in a short while, call 911.

Heat stroke happens when the body is overwhelmed by heat and can’t control its temperature. Heat stroke is potentially fatal so immediate medical attention is critical.

If you are with a senior who is experiencing an elevated body temperature, is exhibiting confusion, combativeness, bizarre behavior, is headachy, feeling faint or is staggering, call 911 immediately. Other symptoms to look for include: strong rapid pulse, dry, flushed skin, lack of sweating and vomiting.

As Mainers, we are serious about staying warm in the winter. While hypothermia due to cold weather is certainly a concern for seniors, heat-related illness is just as dangerous.

Air conditioners can be as useful in summer as a wood stove is in the winter. It is all about keeping your body temperature in normal range. Even though summer is so much shorter than Maine’s long, cold winter, the heat coupled with high humidity can quickly equal disaster for a senior. Remember, as we age, our bodies’ ability to release heat by sweating is blunted, making it particularly dangerous to stay in very warm environments for long periods of time.

The key is to reduce or even prevent the risks that extreme heat can cause. Talk to your primary care provider about your individual risk factors. To beat the heat, give serious thought to an air conditioner. A small one runs about $100 to $150, is easy to install and makes a huge difference. If an air conditioner is not possible, a window or table fan can create a cooling and refreshing breeze.

At night, open windows on opposite sides of the building to create cross-ventilation. During the day, close windows, blinds and curtains and drink plenty of water. Sit in front of a fan and lightly mist your legs and arms, which will cool your skin as the water evaporates. You can also apply a cold, wet washcloth to wrists and neck.

Older people may not feel the heat accurately and consequently put themselves at risk by wearing too much clothing. Lightweight, light-colored, loose-fitting garments made of natural fibers such as cotton or linen are best.

The best way to stay safe in the heat is to take it seriously and pay attention to warning signs.

Ice Cold Beer or Gin & Tonic: watch alcohol consumption!

Wednesday, July 28th, 2010

This summer’s high temperatures and humidity in Maine and over the entire country make that frosty glass of beer or the ice clinking in a gin and tonic even more appealing, but beware! Alcohol is not a good hydration source and can lead to multiple problems for seniors.

cold_beerAlcohol is a diuretic. It flushes water from the body and causes dehydration, which can lead to the muscle cramping, dizziness, faintness and nausea of heat stroke.

Although one or two alcoholic drinks a day are touted as safe and even beneficial, older adults have to be very careful about combining drinking with antidepressants, sedatives or other drugs, and aware of alcohols interaction with other health issues like diabetes, hepatitis and gout.

Older people are also more impaired by alcohol than their younger counterparts, perhaps because alcohol is metabolized and removed from the body differently once you age. Even moderate amounts of alcohol can cause impairment in people over 50. In one study in Florida, adults 50-74 who consumed two drinks took 5 seconds longer to complete a task than adults 23-35 who’d had the same amount of alcohol. That’s a significant amount of time if you’re driving a car, negotiating a sandy beach or crossing the street! (A control group found that both ages took the same amount of time to complete the task without alcohol.)

So if you’re drinking, follow some easy common-sense rules.

  • Drink a full glass of water for every alcoholic beverage you consume.
  • Limit your alcohol intake. Set your limit BEFORE you start drinking.
  • Allow extra time to metabolize your cocktail or beer before undertaking any task, like driving home from the family gathering or putting burgers on a hot grill.
  • Pay attention to how much your friends are drinking, and coach each other on staying safe.

When you’ve finished mowing the lawn, it’s probably good to have a big glass of water before you settle into the shade with an icy beer. And give yourself plenty of time before you set out on your next chore.

Heat Stroke: Guard Against Too Much Heat!

Tuesday, July 6th, 2010

We’ve enjoyed a really nice May and June, but summer is heat big time with this heat wave starting Independence Day weekend.Every summer, we have heat waves and hear about people suffering from various kinds of heat sickness, ranging from the cramps of heat exhaustion to the real emergency of heat stroke.

How can we guard against too much heat? And how do we recognize heat-related illnesses? There’s a lot of information on the web and available from your doctor’s offices, and lots to be said for common sense!

How to Recognize Heat-related Illness

Anyone can suffer from the heat, but it becomes especially dangerous to infants, athletes, outdoor workers, and the elderly. Elders dealing with heart, lung or kidney diseases or who are taking medications are often more vulnerable to heat. They also sweat less than younger people.

Physical symptoms of heat exhaustion include nausea, vomiting, fatigue, weakness, headache, muscle cramps and aches and dizziness. Dehydration causes this, usually loss of fluid through sweating. Your blood pressure drops and circulation decreases, which might cause fatigue, fainting or collapse. Heat cramps sometimes follow exercise in hot conditions.

There are generally runners suffering from heat exhaustion following every Beach to Beacon Road Race, and the treatment includes replacing fluids, sometimes intravenously. We also hear of elders suffering heat exhaustion when their environment simply gets too warm for their body to tolerate. Air conditioning, fans, cool drinks, light clothing and shady porches can help. Be sure to drink a lot of water in hot weather, a cup every half hour. Cooling sponge baths can help keep body temperature under control.

Heat stroke is more dangerous and symptoms can sometimes look like a heart attack. People can have symptoms of heat exhaustion before they progress to heat stroke. Common symptoms of heat stoke include high body temperature, absence of sweating, with hot red or flushed dry skin, rapid pulse, difficulty breathing, strange behavior, hallucinations, confusion and disorientation, agitation, seizures and coma. Heat stroke is extremely serious and patients are treated like heart attack or stroke victims. If you think someone is suffering from heat stroke, seek medical attention immediately, and call emergency services. Loosen clothing and cool the victim with tepid water and fanning until help arrives.

How to Prevent Heat Sicknesses

Be aware of the weather, and don’t over heat to begin with! Think carefully before heavy exercise, tennis, gardening or lawn mowing in mid-day or when it’s hot. Plan those activities for early in the morning or after the sun has set. Drink a lot of water over the course of the whole day, and wear lightweight, loose clothing. Stay in the shade and use an air conditioner or fan. Wear a light hat to protect your head when you go out. (This is why the southern ladies carried parasols.) Avoid alcohol, coffee, tea or other drinks with caffeine, which promote dehydration. Some folks I know time their grocery shopping or mall walking for when they can benefit most from public air conditioning. They attend afternoon matinees at air-conditioned theaters and take advantage of a price discount as well.

When the dog days hit, stay relaxed and hydrated. Your doctor or health care provider has more information on avoiding heat problems. Enjoy the sun in moderation!
