Hot weather health emergencies

These self-help measures are not a substitute for medical care but may help you recognize and respond promptly to warning signs of trouble. Your best defense against heat-related illness is prevention. Staying cool and making simple changes in your fluid intake, activities, and clothing during hot weather can help you remain safe and healthy.

Even short periods of high temperatures can cause serious health problems. Two common problems are heat stroke and heat exhaustion.

Heat stroke

Heat stroke occurs when the body is unable to regulate its temperature. The body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106°F or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided.

Recognizing heat stroke

Warning signs of heat stroke vary but may include:

• An extremely high body temperature (above 103°F, orally)
• Red, hot, and dry skin (no sweating)
• Rapid, strong pulse
• Throbbing headache

• Dizziness
• Nausea
• Confusion
• Unconsciousness

What to Do

If you see any of these signs, you may be dealing with a life-threatening emergency. Have someone call for immediate medical assistance while you begin cooling the victim. Do the following:

• Get the victim to a shady area.

• Cool the victim rapidly using whatever methods you can. For example, immerse the victim in a tub of cool water; place the person in a cool shower; spray the victim with cool water from a garden hose; sponge the person with cool water; or if the humidity is low, wrap the victim in a cool, wet sheet and fan him or her vigorously.

• Monitor body temperature, and continue cooling efforts until the body temperature drops to 101-102°F.

• If emergency medical personnel are delayed, call the hospital emergency room for further instructions.

• Do not give the victim alcohol to drink.

• Get medical assistance as soon as possible.

Sometimes a victim's muscles will begin to twitch uncontrollably as a result of heat stroke. If this happens, keep the victim from injuring himself, but do not place any object in the mouth or provide any fluids. If there is vomiting, make sure the airway remains open by turning the victim on his or her side.

Heat exhaustion

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.

Recognizing heat exhaustion

Warning signs of heat exhaustion include:

• Heavy sweating
• Paleness
• Muscle cramps

• Tiredness
• Weakness
• Dizziness

• Headache
• Nausea or vomiting
• Fainting

The skin may be cool and moist. The victim's pulse rate will be fast and weak, and breathing will be fast and shallow. If heat exhaustion is untreated, it may progress to heat stroke. Seek medical attention immediately if:

• Symptoms are severe.

• The victim has heart problems or high blood pressure.

Otherwise, help the victim to cool off, and seek medical attention if symptoms worsen or last longer than one hour.

What to do

Cooling measures that may be effective include:

• Cool, nonalcoholic beverages, as directed by your physician
• Rest
• Cool shower, bath, or sponge bath

• An air-conditioned environment
• Lightweight clothing

Heat cramps

Heat cramps usually affect people who sweat a lot during strenuous activity. This sweating depletes the body's salt and moisture. The low salt level in the muscles causes painful cramps. Heat cramps may also be a symptom of heat exhaustion.

Recognizing heat cramps

Heat cramps are muscle pains or spasms, usually in the abdomen, arms, or legs, that may occur in association with strenuous activity. If you have heart problems or are on a low-sodium diet, get medical attention for heat cramps.

What to do

If medical attention is not necessary, take these steps:

• Stop all activity, and sit quietly in a cool place.

• Drink clear juice or a sports beverage.

• Do not return to strenuous activity for a few hours after the cramps subside, because further exertion may lead to heat exhaustion or heat stroke.

• Seek medical attention for heat cramps if they do not subside in 1 hour.

Sunburn

Sunburn should be avoided because it damages the skin. Although the discomfort is usually minor and healing often occurs in about a week, a more severe sunburn may require medical attention.

Recognizing sunburn

Symptoms of sunburn are well known:

Skin becomes red, painful, and abnormally warm after sun exposure.

Sunburn treatment

Consult a doctor if the sunburn affects an infant younger than 1 year of age or if these symptoms are present:

• Fever
• Fluid-filled blisters
• Severe pain

Remember these tips when treating sunburn:

• Avoid repeated sun exposure.
• Apply cold compresses or immerse the sunburned area in cool water.
• Apply moisturizing lotion to affected areas. Do not use salve, butter, or ointment.
• Do not break blisters.

Heat Rash

Heat rash is a skin irritation caused by excessive sweating during hot, humid weather. It can occur at any age but is most common in young children.

Recognizing heat rash

Heat rash looks like a red cluster of pimples or small blisters. It is more likely to occur on the neck and upper chest, in the groin, under the breasts, and in elbow creases.

Heat rash treatment

The best treatment for heat rash is to provide a cooler, less humid environment. Keep the affected area dry. Dusting powder may be used to increase comfort, but avoid using ointments or creams . they keep the skin warm and moist and may make the condition worse.

Treating heat rash is simple and usually does not require medical assistance. Other heat-related problems can be much more severe.

Pet safety

• Don't leave your pet in a parked car for a long period of time, even with the windows slightly open. If your car is overheated, your pet could suffer from heat stroke, brain damage or even death.

• If you are away from home for an extended period of time, make sure you have a pet-sitter. Keep current ID on your pet at all times.

• Exercise your pet moderately in warmer weather. Don't make your dog run behind you while you skate or ride your bike.

• Make sure your dog has been tested for heartworm disease.

• Don't leave your pet outside for long periods of time in hot weather. If pets must be outside, please make sure they have access to plenty of clean fresh water, proper shelter and lots of shade.

• To avoid mosquito-borne illness, bring pets in after dusk, apply insect repellent and keep them out of the woods.

Get cool quickly

The best defense for beating the heat is prevention. Staying cool and making simple changes in your fluid intake, activities, and clothing during hot weather can help you remain safe and healthy.

• Apply sunscreen to your skin before going out in the sun.

• Drink plenty of liquids, even if you're not thirsty. Avoid alcoholic drinks because they may lead to dehydration.

• Dress in light-weight, light-colored, loose-fitting clothing.

• Avoid midday heat and do not engage in vigorous activity during the hottest part of the day, between noon and 4 p.m.

• Wear a hat or umbrella to block the sun's rays.

• Eat light. Avoid hot, heavy meals and opt for foods high in water content: fruits, salads and soups.

• Eat out. When the temperature rises, and you don't have air conditioning, drop by your favorite (cool) restaurant. No cooking to heat up the kitchen and you, and no dish washing.

• Use air conditioning. If the temperature is 90 degrees F or above, fans alone usually cannot protect against heat-related illness. If you don't have a unit at home, you can benefit by spending time at the movies, library or in any air-conditioned building. Take a walk at the mall.

• No air conditioning? Make your own! Fill a bowl with ice and place it in front of your fan. Or, make an icy neck wrap. Place ice cubes in a wet hand towel or wash cloth and place it on the back of your neck. Gently rub the cloth up and down your neck ... ahh. Icy bliss!

• Splash around in the kiddie pool! If you don't already have little ones, go ahead and get a pool anyway. You'll certainly be using it next summer. Even sitting under a shady tree and dipping your feet while relaxing with a good book will bring your temperature down.

• No kiddie pool? Put on your bathing suit and have fun running through the sprinklers!

• Take baths and showers. Because water conducts heat away from the body, bathing in tepid water is a good cooling technique.

• Watch out for signs of dehydration or overheating (headache, fatigue, dizziness and nausea).
