⚡ Staying Safe in Extreme Heat

Extreme heat can cause dehydration, heat exhaustion, heat stroke, burns, and worsening of existing medical conditions. Older adults, infants, outdoor workers, athletes, people without air conditioning, and people with certain health conditions may be especially vulnerable.

Heat-related illness can develop indoors as well as outside. Do not wait until someone feels severely ill before moving them to a cooler place.

Prepare for Hot Weather

Before temperatures rise:

  • Check the forecast and heat alerts.
  • Make sure fans and air conditioners work.
  • Identify an air-conditioned place you can visit.
  • Close curtains or blinds that receive direct sunlight.
  • Refill important medication.
  • Keep drinking water available.
  • Freeze water bottles or cold packs.
  • Plan errands and outdoor activities for cooler hours.
  • Check on people who may need help.
  • Make a plan for power outages.

Libraries, community centers, shopping centers, and designated cooling centers may provide relief when a home becomes dangerously hot.

Stay Hydrated

Drink water regularly instead of waiting until you feel extremely thirsty.

Possible signs of dehydration include:

  • Dry mouth
  • Headache
  • Dizziness
  • Weakness
  • Unusual tiredness
  • Dark urine
  • Reduced urination
  • Confusion

Avoid excessive alcohol because it can contribute to dehydration and impair your ability to recognize symptoms.

If a doctor has told you to limit fluids because of heart, kidney, liver, or another medical condition, ask how to manage hydration during hot weather. Do not change a medical fluid restriction on your own.

Keep Your Body Cool

  • Stay in air conditioning when possible.
  • Take cool showers or baths.
  • Apply cool, damp cloths to the skin.
  • Wear lightweight, loose-fitting clothing.
  • Choose light-colored clothing.
  • Limit use of ovens and other heat-producing appliances.
  • Rest during the hottest part of the day.
  • Move to a lower or cooler level of the building.
  • Use fans only when they provide relief and indoor conditions are not dangerously hot.

A fan does not lower body temperature in the same way that air conditioning does. When indoor temperatures become dangerously high, relocate to an air-conditioned place.

Plan Outdoor Activity Carefully

If you must be outside:

  • Go during the cooler morning or evening hours.
  • Drink water before, during, and after activity.
  • Take frequent breaks.
  • Rest in shade or air conditioning.
  • Wear a wide-brimmed hat.
  • Use sunscreen.
  • Reduce the length and intensity of activity.
  • Work or exercise with another person.
  • Stop if you feel faint, weak, confused, or nauseated.

Never leave a child, older adult, person with a disability, or pet in a parked vehicle. A vehicle can become dangerously hot very quickly, even when the windows are partly open.

Recognize Heat Cramps

Heat cramps are painful muscle spasms that may occur during heavy activity or sweating.

If someone develops heat cramps:

  • Stop the activity.
  • Move to a cool place.
  • Rest.
  • Drink water or an appropriate electrolyte beverage.
  • Avoid returning to strenuous activity for several hours.

Seek medical advice if the cramps are severe, last longer than an hour, or occur in someone with a heart condition or fluid restriction.

Recognize Heat Exhaustion

Possible signs include:

  • Heavy sweating
  • Cool, pale, or clammy skin
  • Headache
  • Dizziness
  • Weakness
  • Nausea or vomiting
  • Muscle cramps
  • Fast pulse
  • Fainting

If heat exhaustion is suspected:

  1. Stop the activity.
  2. Move the person to an air-conditioned or shaded place.
  3. Loosen or remove unnecessary clothing.
  4. Apply cool, wet cloths.
  5. Use a fan if it helps.
  6. Offer small sips of cool water if the person is awake and able to swallow.
  7. Monitor the person closely.

Call 911 if symptoms worsen, the person becomes confused, cannot drink, repeatedly vomits, loses consciousness, or does not begin improving.

Recognize Heat Stroke

Heat stroke is a life-threatening emergency.

Possible warning signs include:

  • Confusion
  • Unusual behavior
  • Slurred speech
  • Loss of coordination
  • Seizure
  • Loss of consciousness
  • Very hot skin
  • Rapid breathing or pulse
  • Severe headache
  • A very high body temperature

The person may be sweating heavily or may have dry skin. Do not use sweating alone to decide whether heat stroke is present.

If heat stroke is suspected:

  1. Call 911 immediately.
  2. Move the person to a cooler location.
  3. Remove excess clothing.
  4. Cool the person with cold water, wet towels, ice packs, or another available cooling method.
  5. Place cold packs near the neck, armpits, and groin when available.
  6. Continue cooling until emergency help arrives.
  7. Monitor breathing and responsiveness.

Do not give fluids to someone who is confused, having a seizure, vomiting repeatedly, unconscious, or unable to swallow safely.

Medication and Heat

Some prescription and over-the-counter medications can affect sweating, thirst, circulation, alertness, or the body’s ability to control temperature.

Ask a doctor or pharmacist whether any of your medications require special precautions during hot weather.

Do not stop or change medication on your own. Store medication according to its instructions, and do not leave it in a hot vehicle.

Protect Food During a Power Outage

During a heat-related outage:

  • Keep refrigerator and freezer doors closed.
  • Use appliance thermometers when available.
  • Move temperature-sensitive medication only according to professional instructions.
  • Discard food that may have remained at an unsafe temperature.
  • Never taste food to decide whether it is safe.

Use generators outdoors and well away from doors, windows, and vents. Never use a grill, camping stove, or generator inside a home, garage, basement, or enclosed porch.

Check on Other People

Contact relatives, friends, and neighbors who:

  • Live alone
  • Are older
  • Have limited mobility
  • Do not have air conditioning
  • Depend on medical equipment
  • Take medication that affects heat tolerance
  • May have difficulty obtaining water
  • May not recognize heat-related symptoms

If someone’s home is dangerously hot, help them reach a cooling center or another air-conditioned location.

Quick Heat-Safety Checklist

  • Check heat alerts.
  • Stay in air conditioning when possible.
  • Drink water regularly.
  • Follow medical fluid restrictions.
  • Wear lightweight clothing.
  • Avoid strenuous activity during the hottest hours.
  • Never leave anyone in a parked vehicle.
  • Check on people who may need help.
  • Recognize heat exhaustion.
  • Call 911 for possible heat stroke.

⚡ Staying Safe in Extreme Heat

Extreme heat can cause dehydration, heat exhaustion, heat stroke, fainting, and worsening of existing medical conditions. High humidity makes it harder for the body to cool itself because sweat does not evaporate as effectively.

Older adults, infants, outdoor workers, athletes, people without air conditioning, and people with certain health conditions may be especially vulnerable.

Check the forecast and local heat alerts. Do not wait until you feel sick before taking precautions.

Stay Cool

During extreme heat:

  • Spend time in an air-conditioned location.
  • Close blinds or curtains during the hottest part of the day.
  • Use fans only when indoor conditions are not dangerously hot.
  • Wear lightweight, loose-fitting clothing.
  • Take cool showers or baths.
  • Place cool, damp cloths on your skin.
  • Avoid using the oven when possible.
  • Limit outdoor activity during the hottest hours.
  • Rest frequently.

If your home becomes dangerously hot, go to a cooling center, library, shopping center, community building, or another air-conditioned location.

A fan may create airflow, but it does not lower the room temperature. In extreme indoor heat, relying on a fan alone may not provide enough protection.

Drink Fluids Appropriately

Drink water regularly. Do not wait until you feel extremely thirsty.

  • Carry water when leaving home.
  • Drink before, during, and after physical activity.
  • Limit alcohol.
  • Be cautious with large amounts of caffeine.
  • Replace fluids lost through heavy sweating.
  • Offer water regularly to people who may not recognize thirst.

Some people with heart failure, kidney disease, liver disease, or other medical conditions must limit fluids. If you have been given a fluid restriction, ask your healthcare professional how to stay safe during extreme heat.

Know Whether Medication Increases Your Risk

Certain medications can affect sweating, hydration, blood pressure, alertness, or the body’s ability to regulate temperature.

Ask a doctor or pharmacist whether hot weather may affect you if you take:

  • Diuretics
  • Blood-pressure medication
  • Antihistamines
  • Sedatives
  • Certain psychiatric medications
  • Stimulants
  • Medication that causes dizziness
  • Several medications together

Do not stop or change medication on your own.

Some medications must also be protected from high temperatures. Follow the storage instructions and ask a pharmacist what to do during a power outage.
