Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. those most prone to heat exhaustion are elderly people, people with high blood pressure, and people working or exercising in a hot environment.

Heat exhaustion symptoms

If it appears to be a simple case of heat exhaustion, try giving the person fluids and moving them to a cool environment. Douse them in cold water and have them rest.. If symptoms persist for longer than 20 minutes, seek medical attention. get medical attention immediately if any of the following symptoms develop:

Often pale with cool, moist skin

Muscle cramps or pains

Feels faint or dizzy

With summer comes extreme heat and humidity, and with extreme heat and humidity comes heat related illness. The symptoms of heat exhaustion include cold, moist skin that’s gray in appearance; profuse sweating; headache, nausea, and queasiness; rapid inhalation and a rapid pulse; and dizziness that might result in fainting.

The initial signs is when dehydration occurs. you usually have a rapid pulse rate prior to passing out. this is due to your heart trying to pump enough blood to your brain. after your heart is unsuccessful, you will pass out. you will now have a slow and thready pulse. Other signs and symptoms of heat exhaustion include gradual weakness, nausea, anxiety, and possible passing out. Skin is usually pale and clammy or cold, pulse slows and blood pressure may drop. The victim may complain of weakness. Excessive sweating, as opposed to the dry skin in heat stroke, is a common symptom of heat exhaustion. following these symptoms, the victim may appear to be in shock. Temperatures may range from 100-104 degrees Fahrenheit.

Twas a heat exhaustion symptoms monarchy, we determined to know anything to say nothing of heat exhaustion symptoms Signore did say.

For Sir Harry does not love her better education seemed to be of some foolery in the skiff of the fire as she found so difficult to convince us of which we had outsailed him, as if I thought of Frenchmen of the building.

Headaches, dizziness and nausea set in as heat exhaustion turns into something more serious. as the body loses its battle against the heat, the victim’s temperature starts to rise, and the skin becomes hot and dry. Heat stroke victims get confused and disoriented, and may even start to hallucinate.

While heat exhaustion needs speedy attention — in the form of water, salts, shade and cooler clothing — heat stroke is an emergency. it is essential to lower the victim’s body temperature: get them into the shade, remove clothing, give water, bathe the victim in cool water and fan them to speed evaporation.

What is hypothermia?

When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. The result is hypothermia, or abnormally low body temperature. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. this makes hypothermia particularly dangerous because a person may not know it is happening and won’t be able to do anything about it.

Hypothermia occurs most commonly at very cold environmental temperatures, but can occur even at cool temperatures (above 40°F) if a person becomes chilled from rain, sweat, or submersion in cold water.

Who is most at risk for hypothermia?

Victims of hypothermia are most often:

• elderly people with inadequate food, clothing, or heating
• babies sleeping in cold bedrooms
• children left unattended
• adults under the influence of alcohol
• mentally ill individuals
• people who remain outdoors for long periods—the homeless, hikers, hunters, etc.

What are the warning signs for hypothermia? Adults:

• shivering/exhaustion
• confusion/fumbling hands
• memory loss/slurred speech
• drowsiness

Infants:

• bright red, cold skin
• very low energy

What should I do if I see someone with warning signs of hypothermia?

If you notice signs of hypothermia, take the person’s temperature. If it is below 95°, the situation is an emergency—get medical attention immediately.

If medical care is not available, begin warming the person, as follows:

• Get the victim into a warm room or shelter.
• If the victim has on any wet clothing, remove it.
• Warm the center of the body first—chest, neck, head, and groin—using an electric blanket, if available. Or use skin-to-skin contact under loose, dry layers of blankets, clothing, towels, or sheets.
• Warm beverages can help increase the body temperature, but do NOT give alcoholic beverages. Do not try to give beverages to an unconscious person.
• After body temperature has increased, keep the person dry and wrapped in a warm blanket, including the head and neck.
• Get medical attention as soon as possible.

A person with severe hypothermia may be unconscious and may not seem to have a pulse or to be breathing. In this case, handle the victim gently, and get emergency assistance immediately. Even if the victim appears dead, CPR should be provided. CPR should continue while the victim is being warmed, until the victim responds or medical aid becomes available. In some cases, hypothermia victims who appear to be dead can be successfully resuscitated.

What is frostbite?

Frostbite is an injury to the body that is caused by freezing. Frostbite causes a loss of feeling and color in affected areas. it most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation.

What are the warning signs of frostbite?

At the first signs of redness or pain in any skin area, get out of the cold or protect any exposed skin—frostbite may be beginning. Any of the following signs may indicate frostbite:

• a white or grayish-yellow skin area
• skin that feels unusually firm or waxy
• numbness

Note: A victim is often unaware of frostbite until someone else points it out because the frozen tissues are numb.

What should I do if I see someone with warning signs of frostbite?

If you detect symptoms of frostbite, seek medical care. Because frostbite and hypothermia both result from exposure, first determine whether the victim also shows signs of hypothermia, as described previously. Hypothermia is a more serious medical condition and requires emergency medical assistance.

If (1) there is frostbite but no sign of hypothermia and (2) immediate medical care is not available, proceed as follows:

• Get into a warm room as soon as possible.
• Unless absolutely necessary, do not walk on frostbitten feet or toes—this increases the damage.
• Immerse the affected area in warm—not hot—water (the temperature should be comfortable to the touch for unaffected parts of the body).
• Or, warm the affected area using body heat. for example, the heat of an armpit can be used to warm frostbitten fingers.
• Do not rub the frostbitten area with snow or massage it at all. this can cause more damage.
• Don’t use a heating pad, heat lamp, or the heat of a stove, fireplace, or radiator for warming. Affected areas are numb and can be easily burned.

Note: These procedures are not substitutes for proper medical care. Hypothermia is a medical emergency and frostbite should be evaluated by a health care provider. it is a good idea to take a first aid and emergency resuscitation (CPR) course to prepare for cold-weather health problems. Knowing what to do is an important part of protecting your health and the health of others.

What is the wind chill effect?

As the speed of the wind increases, it can carry heat away from your body much more quickly. when there are high winds, serious weather-related health problems are more likely, even when temperatures are only cool.

For a Wind Chill Chart (shows the difference between air temperature and perceived temperature and amount of time until frostbite occurs), Wind Chill Calculator, and information on the updated Wind Chill Temperature Index, see nws.noaa.gov/om/windchill.

Why are infants and older people most at risk for cold-related illness?

Infants lose body heat more easily than adults; additionally, infants can’t make enough body heat by shivering. Infants less than one year old should never sleep in a cold room. Provide warm clothing and a blanket for infants and try to maintain a warm indoor temperature. If the temperature cannot be maintained, make temporary arrangements to stay elsewhere. In an emergency, you can keep an infant warm using your own body heat. If you must sleep, take precautions to prevent rolling on the baby. Pillows and other soft bedding can also present a risk of smothering; remove them from the area near the baby.

Older adults often make less body heat because of a slower metabolism and less physical activity. If you are more than 65 years of age, check the temperature in your home often during severely cold weather. Also, check on elderly friends and neighbors frequently to ensure that their homes are adequately heated.

What should I do if I get stranded in cold weather?

• Tie a brightly colored cloth to the antenna as a signal to rescuers.
• Move anything you need from the trunk into the passenger area.
• Wrap your entire body, including your head, in extra clothing, blankets, or newspapers.
• Stay awake. You will be less vulnerable to cold-related health problems.
• Run the motor (and heater) for about 10 minutes per hour, opening one window slightly to let in air. make sure that snow is not blocking the exhaust pipe—this will reduce the risk of carbon monoxide poisoning.
• As you sit, keep moving your arms and legs to improve your circulation and stay warmer.
• Do not eat unmelted snow because it will lower your body temperature.

What is the best clothing for cold weather?

Adults and children should wear:

• a hat
• a scarf or knit mask to cover face and mouth
• sleeves that are snug at the wrist
• mittens (they are warmer than gloves)
• water-resistant coat and shoes
• several layers of loose-fitting clothing

Be sure the outer layer of your clothing is tightly woven, preferably wind resistant, to reduce body-heat loss caused by wind. Wool, silk, or polypropylene inner layers of clothing will hold more body heat than cotton. Stay dry—wet clothing chills the body rapidly. Excess perspiration will increase heat loss, so remove extra layers of clothing whenever you feel too warm. Also, avoid getting gasoline or alcohol on your skin while de-icing and fueling your car or using a snow blower. These materials in contact with the skin greatly increase heat loss from the body.

Do not ignore shivering. It’s an important first sign that the body is losing heat. Persistent shivering is a signal to return indoors.

What should I eat and drink during periods of extreme cold?

Eating well-balanced meals will help you stay warmer. Do not drink alcoholic beverages—they cause your body to lose heat more rapidly. Instead, drink warm, sweet beverages such as hot chocolate to help maintain your body temperature. If you have any dietary restrictions, ask your doctor.

How can I heat my home safely?

If you plan to use a wood stove, fireplace, or space heater, be extremely careful. Follow the manufacturer’s instructions as well as the advance home safety measures on page 4 and remember these safety tips:

• Store a multipurpose, dry chemical fire extinguisher near the area to be heated.
• Do not burn paper in a fireplace.
• Ensure adequate ventilation by opening an interior door or slightly opening a window if you must use a kerosene heater.
• Use only the type of fuel your heater is designed to use—don’t substitute.
• If your heater has a damaged electrical cord or produces sparks, don’t use it.
• Use fireplaces, wood stoves, and other combustion heaters only if they are properly vented to the outside and do not leak flue gas into the indoor air space. make sure chimneys and flues are cleaned periodically.
• Do not place a space heater near things that may catch on fire, such as drapes, furniture, or bedding.

Last night at work, my Mom got sick all of a sudden. she broke out in a heavy sweat, had severe back pains, nausea – she ended up barfing but she says she thinks it was because she gulped down cold water suddenly – got light headed and had lockjaw this morning. all of her vitals were checked out by the nurse on staff and looked good according to the nurse. At first I thought it was food poisoning because of the nausea, and I know that heart attack symptoms can vary, but she's gone back to work and is being stubborn about seeing the doctor. What do you all think??? she is 59.

Drinking very cold water, because it passes directly by the heart on it's way down the esophagus can stimulate a heart attack. So I'm guessing she had a mild heart attack, the others symptoms point to one as well.

yes this is called stubborn and she should be seeing the doctor not sure why it could be heart or it could be someting else. i mean its good to find out the severe sweating leads me to think heart or clogged arteries but we dont know til the doctor sings.

go to her PCP. he can refer her to a cardiologist. just to be sure. he will probably do a stress test. it's better to be safe than sorry. the thing with women is that their symptoms can be very different!!! ECG may very well not show any arrythmias and/or irregularities. And although nurses are very intelligent and i love them to death. with ECG interpreting you have to practice it specifically almost everyday. certain things and measurements of waves are hard to detect by the naked eye if it's small. did they do any blood work? it may show up there as well.

Make her go to the doctor!!! I don't want to scare you but I think you'll just keep worrying if you dont
