Heat stroke is the most serious, but heat exhaustion is significant as well.The main thing is to prevent these things.
The signs of heat exhaustion typically include heavy sweating, muscle cramps, headache, weakness, or pale and clammy skin. More serious cases can result in nausea or fainting.
If these symptoms persist, medical care is needed.
Heat stroke is diagnosed based on a body temperature of 103 degrees. The symptoms include dizziness; hot, dry skin with no sweating; nausea; confusion; a throbbing headache, and a strong, rapid pulse.
Some people may loss consciousness.
The main thing is to get hydrated or cool the body down. Do whatever you can do to bring the body temperature down.
Heat exhaustion might not necessarily progress to heat stroke, but it is possible.
Just make sure symptoms improve quickly.
The primary difference between the two conditions is the perspiration factor.
With heat exhaustion, you are perspiring, but with heat stroke, you are no longer sweating.
With heat stroke, you are unable to sweat.
Heat stroke can even progress to death, so it is serious when it progresses to heat stroke.
Experts suggest the best prevention methods are — staying in air-conditioned rooms, staying in the coolest room in the house, staying in public areas that are cool, and avoiding the sun from 10 a.m.-4 p.m.
Drinking fluids is also a good method, as long as they are not caffeinated or alcoholic.
Those drinks can cause dehydration.
Officials also suggest checking on the elderly or people without air conditioning.
The elderly might not have that feeling of thirst, or their medications might affect their response to heat. Remind them to stay hydrated.
Because it still happens, Experts are still making a plea concerning leaving children in hot cars.
The temperature can rise in just a few minutes. It happens, so anything people can do to remind themselves (not to leave a child in the car)...
They say that if temperatures are in the low to mid-70s, the temperature can jump up in the car by 19 degrees in just 10 minutes. www.albanyherald.com/news/headlines/Severe
Some hints to remember:
**Avoid being outside during the hottest part of the day, 11 a.m. to 4 p.m. Wear light-colored and lightweight clothing, a hat, and remember that 100 percent cotton clothing tends to hold sweat, making it harder for your body to cool off.
**Thirst isn't always a good sign of hydration status. In children, the thirst mechanism isn't fully developed, and in seniors, the sense of thirst has diminished. By the time your brain signals thirst, you may have lost 1 percent of your body weight -- about 3 cups of sweat for a 150-pound person.
**Urine color is an important indicator of hydration. A well-hydrated person's urine will be almost clear. Darker colors indicate less hydration. Not having to urinate at all after intense workouts is a warning sign of real dehydration.
**If you exercise for less than 90 minutes at a time, cool water (40 degrees F) is all you need to replace fluids. You should drink about 16 ounces of water two hours before exercising, eight ounces every 15 to 20 minutes during exercise, and then at least another 16 ounces after finishing. Drink until your thirst is quenched, and then drink even more to fully rehydrate.
**Sports beverages are appropriate if you're exercising for more than 90 minutes. These beverages should be consumed only during exercise and not before, because they might trigger a hypoglycemic -- or low glucose -- effect, potentially reducing performance. www.nebraska.tv/story/15068374/soaring-tem
Tips for Preventing Heat-Related Illness
Drink more fluids (nonalcoholic), regardless of your activity level. Don’t wait until you’re thirsty to drink. Warning: If your doctor generally limits the amount of fluid you drink or has you on water pills, ask him how much you should drink while the weather is hot.
Don’t drink liquids that contain alcohol or large amounts of sugar–these actually cause you to lose more body fluid. Also, avoid very cold drinks, because they can cause stomach cramps.
Stay indoors and, if at all possible, stay in an air-conditioned place. If your home does not have air conditioning, go to the shopping mall or public library–even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department to see if there are any heat-relief shelters in your area.
Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath, or moving to an air-conditioned place is a much better way to cool off.
Wear lightweight, light-colored, loose-fitting clothing.
NEVER leave anyone in a closed, parked vehicle.
Although any one at any time can suffer from heat-related illness, some people are at greater risk than others. Check regularly on:
Infants and young children
People aged 65 or older
People who have a mental illness
Those who are physically ill, especially with heart disease or high blood pressure
Visit adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.
If you must be out in the heat:
Limit your outdoor activity to morning and evening hours.
Cut down on exercise. If you must exercise, drink two to four glasses of cool, nonalcoholic fluids each hour. A sports beverage can replace the salt and minerals you lose in sweat. Warning: If you are on a low-salt diet, talk with your doctor before drinking a sports beverage. Remember the warning in the first “tip” (above), too.
Try to rest often in shady areas.
Protect yourself from the sun by wearing a wide-brimmed hat (also keeps you cooler) and sunglasses and by putting on sunscreen of SPF 15 or higher (the most effective products say “broad spectrum” or “UVA/UVB protection” on their labels). www.bt.cdc.gov/disasters/extremeheat/heatt
