During South Carolina summers, not only does the temperature rise, but the heat index heads into dangerous territory. Hot weather is not to be taken lightly.
Older adults dehydrate rapidly and need to observe the following rules to ensure that they do not suffer from heat-related problems, especially if they do not have air conditioning in their homes.
- During the hottest part of the day turn off lights and stay in the cooler parts of the house
- Do not close doors or windows during the hottest parts of the day if you do not have air conditioning. Partially opening up windows allows for ventilation. Air trapped inside the house will become warmer during the course of the day
- Don't go outside during the hottest part of the day to shop or work in the yard. If shopping is necessary, go out early in the a.m. or late afternoon
- Drink lots of fluid, preferably water
- If it gets too hot in the house, take a cool bath. Use tepid water, not too hot and not too cold
- You can put cool cloths on pulse points: wrists, ankles, armpits and back/sides of the neck. Continue to apply the damp cloths until you have cooled down
- Wear as little clothing as possible. Dress lightly, in weight of clothes and color
- If the home becomes unbearable and transportation is available, go to a cool place such as the grocery store or the library, or even one of the book stores that allows you to sit and read.
This is also a good time of the year to join your local senior center where you can receive nourishing meals, stay cool and meet new friends. Have a happy and safe summer, everyone.
When working or exercising outdoors during summer, it's extremely important to be aware of the signs and symptoms of heat-related illness, and to take steps to prevent it. The following information, compiled by the American Red Cross, can help you avoid heat-related illnesses such as heat exhaustion or heat stroke.
Warm weather means activities and fun under the sun! Whether you love putting on shorts and feeling the warm outdoors, or find it hot and sticky, everyone must be careful not to let a heat-related illness spoil the day.
Normally, the body has ways of keeping itself cool, by letting heat escape through the skin, and by evaporating sweat (perspiration). If the body does not cool properly or does not cool enough, the victim may suffer a heat-related illness. Anyone can be susceptible although the very young and very old are at greater risk. Heat-related illnesses can become serious or even deadly if unattended.
Preventing Heat-Related Illness
- Dress for the heat. Wear lightweight, light-colored clothing. Light colors will reflect away some of the sun's energy. It is also a good idea to wear hats or to use an umbrella
- Drink water. Carry water or juice (with natural sugar only, not artificial sugar) with you and drink continuously even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body
- Eat small meals and eat more often. Avoid foods that are high in protein which increases metabolic (body) heat
- Avoid using salt or salt tablets unless directed to do so by a physician
- Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the early morning or after 6:00 or 7:00 p.m.
- Stay indoors when possible in the coolest part of the house, away from windows, sun rooms, etc.
- Take regular breaks when engaged in physical activity on warm days. Take time out to find a cool place. If you recognize that you, or someone else, is showing signs of a heat-related illness, stop activity and find a cool place. Remember, have fun, but stay cool!
Know What These Heat-Related Terms Mean
- Heat Wave: More than 48 hours of high heat (90°F or higher) and high humidity (80 percent relative humidity or higher) are expected
- Heat Index: A number in degrees Fahrenheit that tells how hot it really feels with the heat and humidity. Exposure to full sunshine can increase the heat index by 15°F
- Heat cramps: Heat cramps are muscular pains and spasms due to heavy exertion. They usually involve the abdominal muscles or the legs. It is generally thought that the loss of water and salt from heavy sweating causes the cramps
- Heat Exhaustion: Heat exhaustion is less dangerous than heat stroke. It typically occurs when people exercise heavily or work in a warm, humid place where body fluids are lost through heavy sweating. Fluid loss causes blood flow to decrease in the vital organs, resulting in a form of shock. With heat exhaustion, sweat does not evaporate as it should, possibly because of high humidity or too many layers of clothing. As a result, the body is not cooled properly. Signals include cool, moist, pale, flushed or red skin; heavy sweating; headache; nausea or vomiting; dizziness; and exhaustion. Body temperature will be near normal
- Heat Stroke: Also known as sunstroke, heat stroke is life-threatening. The victim's temperature control system, which produces sweating to cool the body, stops working. The body temperature can rise so high that brain damage and death may result if the body is not cooled quickly. Signals include hot, red and dry skin; changes in consciousness; rapid, weak pulse; and rapid, shallow breathing. Body temperature can be very high--sometimes as high as 105°F
Stages of Heat-Related Illness
Heat-related illness usually comes in stages. The signal of the first stage is heat cramps in muscles. These cramps can be very painful. If you are caring for a person who has heat cramps, have him or her stop activity and rest. If the person is fully awake and alert, have him or her drink small amounts of cool water or a commercial sports drink. Gently stretch the cramped muscle and hold the stretch for about 20 seconds, then gently massage the muscle. Repeat these steps if necessary. If the victim has no other signals of heat-related illness, the person may resume activity after the cramps stop.
The signals of the next, more serious stage of a heat-related illness (often called heat exhaustion) include--
- Cool, moist, pale skin (the skin may be red right after physical activity).
- Dizziness and weakness or exhaustion.
- The skin may or may not feel hot.
The signals of the late stage of a heat-related illness (often called heat stroke) include--
- Decreased alertness level or complete loss of consciousness.
- High body temperature (sometimes as high as 105°F)
- Skin may still be moist or the victim may stop sweating and the skin may be red, hot and dry.
- Rapid, weak pulse.
- Rapid, shallow breathing.
This late stage of a heat-related illness is life threatening. Call 9-1-1 or the local emergency number.
General Care for Heat Emergencies
- Cool the Body
- Give Fluids (only if the person is awake and talking and can swallow)
- Minimize Shock
For heat cramps or heat exhaustion: Get the person to a cooler place and have him or her rest in a comfortable position. If the person is fully awake and alert, give a half glass of cool water every 15 minutes. Do not let him or her drink too quickly. Do not give liquids with alcohol or caffeine in them, as they can make conditions worse. Remove or loosen tight clothing and apply cool, wet cloths such as towels or wet sheets. Call 9-1-1 or the local emergency number if the person refuses water, vomits or loses consciousness.
For heat stroke: Heat stroke is a life-threatening situation! Help is needed fast. Call 9-1-1 or your local EMS number. Move the person to a cooler place. Quickly cool the body. Wrap wet sheets around the body and fan it. If you have ice packs or cold packs, wrap them in a cloth and place them on each of the victim's wrists and ankles, in the armpits and on the back and sides of the neck to cool the large blood vessels. (Do not use rubbing alcohol because it closes the skin's pores and prevents heat loss.) Watch for signals of breathing problems and make sure the airway is clear. Keep the person lying down.
