Linn County Public Health would like to remind residents to protect themselves against the effects of elevated summer temperatures. According to The National Oceanic and Atmospheric Administration (NOAA), heat is the number one weather-related killer in the United States. As temperature begin to soar to 100°F, the excessive humidity in combination with the heat may leave you dehydrated and could be life threatening. As such it is essential that you take strides to keep you and your family safe. See the list of Heat Relief Locations (PDF) in your area for acting during excessive heat events.
On days of extreme heat, be sure to check in on family, friends and neighbors who are at-risk of falling ill due to the heat. No matter the circumstance, children and pets SHOULD NOT be left in vehicles unattended. In addition, be sure that pets have free access to fresh drinking water and are kept safe from the heat.
Prevent Heat-Related Illness
Individuals at Risk for Heat-Related Illness
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 may be the cause of heat 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.
What to Do
- Stop all activity and sit 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
- You have heart problems
- You are on a low-sodium diet
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. It is the body's response to an excessive loss of the water and salt contained in sweat. 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
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.
What to Do
- Drink cool, nonalcoholic beverages
- Take a cool shower, bath or sponge bath
- Get into an air-conditioned environment
- Wear lightweight clothing
- Seek medical attention immediately if:
- Symptoms are severe
- Symptoms worsen or last longer than 1 hour
- The victim has heart problems or high blood pressure
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.
What to Do
Treating heat rash is simple and usually does not require medical assistance.
- Seek a cooler, less humid environment
- Keep the affected area dry
- Dusting powder may be used to increase comfort
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. Warning signs of heat stroke vary but may include the following:
Recognizing Heat Stroke
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:
What to Do
- Seek medical assistance as soon as possible
- Get the victim to a shady area
- Cool the victim rapidly, using whatever methods you can
- Monitor body temperature and continue cooling efforts until the body temperature drops to 101-102°F
- Do not give the victim anything to drink
- Sometimes a victim's muscles will begin to twitch uncontrollably as a result of heat stroke. If this happens, keep the victim from injuring themselves by moving objects from around the victim
- If emergency medical personnel are delayed, call the hospital emergency room for further instructions
Sunburn should be avoided because it damages the skin. Although the discomfort is usually minor and healing often occurs in about a week, more severe sunburn may require medical attention. Proper sun protection practices such as using sunscreen and wearing appropriate clothing can reduce a person's risk for developing skin cancer.
The skin becomes red, painful and abnormally warm after sun exposure.
What to Do
Consult a doctor if the sunburn affects an infant younger than 1 year of age or if these symptoms are present:
- Fluid-filled blisters
- Severe pain
Also, 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
