Suyin’s bus was late. Even though it was noon on a very hot summer day, she decided to walk from the grocery store to her home. At 72—healthy and active—Suyin thought the heat would be no match for her! Yet, after walking just one block, she felt dizzy and weak.
Too much heat is not safe for anyone. It is even riskier if you are older or if you have health problems. It is important to get relief from the heat quickly. If not, you might begin to feel confused or faint. Your heart could become stressed, and maybe stop beating.
Being hot for too long can cause many illnesses, all grouped under the name hyperthermia (hy-per-ther-mee-uh):
- Heat cramps are the painful tightening of muscles in your stomach area, arms, or legs. Cramps can result from hard work or exercise. While your body temperature and pulse usually stay normal during heat cramps, your skin may feel moist and cool. Take these cramps as a sign that you are too hot and find a way to cool your body down. Be sure to drink plenty of fluids, but not those containing alcohol or caffeine.
- Heat edema is a swelling in your ankles and feet when you get hot. Putting your legs up should help. If that doesn't work fairly quickly, check with your doctor.
- Heat syncope is a sudden dizziness that may come on when you are active in the heat. If you take a form of heart medication known as a beta blocker or are not used to hot weather, you are even more likely to feel faint when in the heat. Putting your legs up and resting in a cool place should make the dizzy feeling go away.
- Heat exhaustion is a warning that your body can no longer keep itself cool. You might feel thirsty, dizzy, weak, uncoordinated, nauseated, and sweat a lot. Your body temperature stays normal, skin feels cold and clammy. Your pulse can be normal or raised. Resting in a cool place, drinking plenty of fluids, and getting medical care should help you feel better soon. If not, this condition can progress to heat stroke.
- Heat stroke is an emergency and it can be life threatening! You need to get medical help right away. Getting to a cool place is very important, but so is treatment by a doctor. Many people die of heat stroke each year. Older people living in homes or apartments without air conditioning or good airflow are at most risk. So are people who don't drink enough water or those with chronic diseases or alcoholism.
Heat Stroke--A Medical Emergency
If you have heat stroke, you need to get medical help right away. Older people living in homes or apartments without air conditioning or fans are at most risk. People who become dehydrated or those with chronic diseases or alcoholism are also at most risk. Signs of heat stroke are:
- Fainting, possibly the first sign,
- Body temperature over 104° F,
- A change in behavior-- confusion, being grouchy, acting strangely, or staggering,
- Dry flushed skin and a strong rapid pulse or a slow weak pulse,
- Not sweating, despite the heat, acting delirious, or being in a coma.
Who is at Risk?
Hundreds of people die from hyperthermia each year during very hot weather. Most are over 50 years old. The temperature outside or inside does not have to hit 100° F for you to be at risk for a heat-related illness. Health problems that put you at risk include:
- Heart or blood vessel problems, poorly working sweat glands, or changes in your skin caused by normal aging.
- Heart, lung, or kidney disease, as well as any illness that makes you feel weak all over or causes a fever.
- Conditions treated by drugs such as diuretics, sedatives, tranquilizers, and some heart and blood pressure medicines. These may make it harder for your body to cool itself by perspiring.
- Taking several drugs for a variety of health problems. Keep taking your prescriptions, but ask your doctor what to do if the drugs you are taking make you more likely to become overheated.
- Being quite a bit overweight or underweight.
- Drinking alcoholic beverages.
How Can I Lower My Risk?
- Drink plenty of liquids-- water or fruit and vegetable juices. Every day you should drink at least eight glasses to keep your body working properly. Heat tends to make you lose fluids so it is very important to drink at least that much, if not more when it is hot. Avoid drinks containing caffeine or alcohol. They make you lose more fluids. If your doctor has told you to limit your liquids, ask him or her what you should do when it is very hot.
- If you live in a home or apartment without fans or air conditioning, be sure to follow these steps to lower your chance of heat problems:
- open windows at night;
- create cross-ventilation by opening windows on two sides of the building;
- cover windows when they are in direct sunlight;
- keep curtains, shades or blinds drawn during the hottest part of the day;
- try to spend at least 2 hours a day (if possible during the hottest part of the day) someplace air-conditioned-- for example, the shopping mall, the movies, the library, a senior center, or a friend's house if you don't have air conditioning.
- Check with your local area agency on aging to see if there is a program that provides window air conditioners to seniors who qualify.
- If you think you can't afford to run your air conditioner in the summer, contact your local area agency on aging or ask at your local senior center. They may know if there are any programs in your community to aid people who need help paying their cooling bills. The local Department of Social Services office may also be able to provide information about the Low Income Home Energy Assistance Program (LIHEAP).
- Ask a friend or relative to drive you to a cool place on very hot days if you don't have a car or no longer drive. Many towns or counties, area agencies, religious groups, and senior citizen centers provide such services. If necessary, take a taxi. Don't stand outside waiting for a bus.
- Pay attention to the weather reports. You are more at risk as the temperature or humidity rise or when there is an air pollution alert in effect.
- Dress for the weather. Some people find natural fabrics such as cotton to be cooler than synthetic fibers. Light-colored clothes reflect the sun and heat better than dark colors. If you are unsure about what to wear, ask a friend or family member to help you select clothing that will help you stay cool.
- Don't try to exercise or do a lot of activities when it is hot.
- Avoid crowded places when it's hot outside. Plan trips during non-rush hour times.
What Should I Remember?
Headache, confusion, dizziness, or nausea when you're in a hot place or during hot weather could be a sign of a heat-related illness. Go to the doctor or an emergency room to find out if you need treatment. To keep heat-related illnesses from becoming a dangerous heat stroke, remember to:
- Get out of the sun and into a cool place--air-conditioning is best.
- Offer fluids, but avoid alcohol and caffeine. Water and fruit and vegetable juices are best.
- Shower, bathe, or at least sponge off with cool water.
- Lie down and rest, if possible in a cool place.
- Visit your doctor or an emergency room if you don't cool down quickly.
