Practice Heat Safety

Stay Cool

  • Drink plenty of water.
  • Be aware of the signs of heat exhaustion and heat stroke. 
  • Apply sunscreen regularly.  
  • Dress in lightweight and light-colored clothing.
  • Limit time outside.
  • Make sure you have a cool place to shelter from the heat. 
  • Avoid outdoor activities, especially strenuous activity, during peak heating times of the day. 
  • If you must work outdoors, work early or very late in the day. 
  • Stay in an air-conditioned place as much as possible.
  • If your home does not have air conditioning, consider visiting the shopping mall or a public library. Even a few hours spent in air conditioning can help your body stay cooler when you return to the heat.
  • Remember that electric fans may provide comfort, but when the temperature is in the high 90s, they will not prevent heat-related illness.
  • Take a cool shower or bath to cool off.
  • Use your stove and oven less to maintain a cooler indoor temperature.

Stay Hydrated

  • Drink more fluids, regardless of your level of activity. Don’t wait until you’re thirsty to drink.
  • Stay away from very sugary or alcoholic drinks — these actually cause you to lose more body fluid. Also, avoid very cold drinks, because they can cause stomach cramps.
  • Heavy sweating removes essential salts and minerals from the body that need to be replenished. A sports drink can help replace the salt and minerals lost in sweat.

Monitor Those at High Risk

Although anyone at any time can suffer from heat-related illness, some people are at greater risk than others:

  • Infants and young children
  • People 65 years of age or older
  • People who are overweight
  • People who overexert during work or exercise
  • People who are physically ill, especially with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation
  • 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 are concerned about a loved one's well-being during a period of dangerous heat, contact the Naperville Police Department at (630) 420-6666 to arrange for a non-emergency wellness check. 

Heat Exhaustion vs. Heat Stroke

Heat Exhaustion

Symptoms

  • Heavy sweating
  • Weakness
  • Cool, pale, and clammy skin
  • Fast and weak pulse
  • Possible muscle cramps
  • Dizziness
  • Nausea or vomiting
  • Fainting

First Aid 

  • Move the person to a cooler environment
  • Lay the person down and loosen clothing
  • Apply cool, wet cloths to as much of the body as possible
  • Fan or move the victim to an air-conditioned room
  • Offer sips of water
  • If a person vomits more than once, seek immediate medical attention

Heat Stroke

Symptoms

  • Altered mental state
  • One or more of the following symptoms: throbbing headache; confusion; nausea; dizziness; shallow breathing; body temperature above 103°F; hot, red, or dry moist skin; rapid and strong pulse; fainting; or losing consciousness

First Aid 

  • Heat stroke is a severe medical emergency. Call 911 or get the victim to a hospital immediately. Delay can be fatal.
  • Move the victim to a cooler, preferably air-conditioned, environment.
  • Reduce body temperature with cool cloths or a bath.
  • Use a fan if heat index temperatures are below the high 90s. A fan can make you hotter at higher temperatures.
  • Do NOT give fluids.

Children, Pets and Vehicles

  • NEVER leave a toddler, disabled person or pet locked in a car.
  • Cars can quickly heat up to dangerous temperatures, even with a window cracked open. While anyone left in a parked car is at risk, children are especially at risk of getting heat stroke or dying.
  • If you have a toddler in your household, lock your cars, even in your own driveway. 
  • When traveling with children, remember to do the following:
    • To remind yourself that a child is in the car, keep a stuffed animal in the car seat. When the child is buckled in, place the stuffed animal in the front with the driver.
    • When leaving your car, check to be sure everyone is out of the car. Do not overlook any children who have fallen asleep in the car.
  • Dangerously hot weather can be just as deadly to animals.
    • Provide ample shade and water.
    • Limit time outside and exercise on hot days.
    • Be mindful of hot pavement, which can burn your pet's paw pads. 

If you see a child or animal in an unattended, parked car, call 911.
