“Cool Places to Go” are public spaces where you can go to safely cool down.

Heat is the leading cause of weather-related deaths in the United States each year. When people are exposed to high heat, it can cause serious health emergencies like heat stroke and heat exhaustion.

Extreme heat describes temperatures that are much hotter than usual. An extreme heat event is two or more days and nights of unusually high heat for a given area. High levels of humidity can cause outdoor temperatures to feel hotter.​

San Bernardino County is expecting more severe, and longer-lasting episodes of extreme heat in California, posing greater danger to the community.

Who Is Most at Risk When It’s Hot?

Summer heat waves can be dangerous, especially for people who may be more sensitive to the heat, including:

  • Those working outdoors or in unconditioned indoor environments
  • Older adults (65+)
  • Infants and children
  • Those with chronic health conditions
  • People with access needs or disabilities
  • Pregnant people
  • Athletes
  • Those without air conditioning
  • Those using pharmaceutical medication or substances
  • Animals

This heat index table shows how hot it feels when combining temperature and humidity, highlighting the risk of heat illness as temperatures rise.

When temperatures are high the body works extra hard to maintain its normal temperature. The body normally cools itself by sweating, but sometimes that is not enough. Heat-related illness occurs when the body cannot cool itself down.

What to Look for:

  • High body temperature (103°F or higher)
  • Hot, red, dry, or damp skin
  • Fast, strong pulse
  • Headache
  • Dizziness
  • Nausea
  • Confusion
  • Losing consciousness (passing out)

What to Do:

  • Call 911 right away-heat stroke is a medical emergency
  • Move the person to a cooler place
  • Help lower the person’s temperature with cool cloths or a cool bath
  • Do not give the person anything to drink

    • You are throwing up
    • Your symptoms get worse
    • Your symptoms last longer than 1 hour

What to Look for:

  • Heavy sweating during intense exercise
  • Muscle pain or spasms

What to Look for:

  • Red clusters of small blisters that look like pimples on the skin (usually on the neck, chest, groin, or in elbow creases)

What to Do:

  • Stay in a cool, dry place
  • Keep the rash dry
  • Use powder (like baby powder) to soothe the rash

Avoid the sun Stay indoors from 10 a.m. to 4 p.m. when the heat is strongest.

Drink plenty of fluids Drink 2 to 4 glasses of water every hour.

Replace salt and minerals Sweating removes salt and minerals from your body, so replenish these nutrients with low-sugar fruit juices or sports drinks during exercise or when working outside.

Avoid alcohol Alcohol can cause dehydration. Drinking alcohol within 24 hours of working in the heat can increase the risk of heat illness.

Pace yourself Reduce physical activity and avoid exercising outdoors during peak heat hours.

Wear heat-safe clothingWear a wide-brimmed hat and light-colored, lightweight, loose-fitting clothes when you are outdoors.

Stay cool indoors Set your air conditioner between 75° and 80°. If you don’t have air conditioning, take a cool shower twice a day and visit a public air-conditioned space.

Monitor those at high risk Use a buddy system to watch each other for signs of heat-related illness. Check in on a friend or neighbor, and have someone check in on you as well.

Use sunscreen It is recommended to use a sun protection factor (SPF) of at least 15 if you need to be in the sun.

Keep pets safe Heat also affects animals. Provide plenty of water and shade, and when possible, keep pets indoors. Never leave your pet alone in a vehicle, even if the window is cracked or open.

These are do-it-yourself (DIY) ways to stay cool when it’s hot.

  • Cool the body with a wet bandana or washcloth around your neck or exposed skin.
  • Place a bowl filled with ice or frozen water bottles in front of a fan.
  • Close windows and curtains during the hottest parts of the day.
  • During cooler parts of the day, open windows and doors to allow cool airflow into the home.
  • Take cool showers or baths to lower your body temperature.
  • Mist yourself with water using a spray bottle or misting fan to keep your skin wet and cool.
  • Position a box fan in a window at night to blow cool air into the home.
  • Hang a damp sheet or laundry in front of a window or fan to allow cool air to be blown into the home.
  • Visit a Cool Place to Go or a cooling center to cool down in a free, public, air-conditioned space.
  • Turn off lights and electronics (like TVs and toasters) when not in use.
  • Use the stove and oven less to maintain cooler temperatures in the home.
  • Set ceiling fans to rotate counter-clockwise, if possible, to improve airflow.

Power outages caused by extreme heat can:

  • Disrupt services such as communications, water, transportation, and waste disposal
  • Close retail businesses, grocery stores, gas stations, ATMs, and banks
  • Cause food spoilage and water contamination
  • Prevent the use of medical devices or medical and senior center facilities

To report an outage, find an outage, learn when your power will be restored, or learn about other types of outages, visit the SoCal Edison Outage Center.
