*Public Health recommends the following tips to keep yourself and others safe during excessive heat:*


* Drink plenty of water and keep hydrated throughout the day
* If you must go out, plan your day to avoid going out during the hottest hours, and wear sunscreen (SPF 15)
* Wear lightweight, light-colored clothes, and wear a hat or use an umbrella
* Cars get very hot inside, even if the windows are ‘cracked’ or open. Never leave children or pets alone in cars. Call 911 if you see a child or pet in a car alone
* Check on those at risk for heat-related illness, like those who are sick or have chronic conditions, older adults, pregnant women, children, those who live alone, pets, and outdoor workers and athletes

If you don’t have air conditioning, follow these tips:


* Stay hydrated and don’t wait until you’re thirsty to drink water
* Take cool showers or baths
* Use your stove and oven less to avoid making your home hotter
* Visit a library, cooling center, shopping mall, or other air-conditioned space. If you need help finding a cool space, call 211.

*Heat-Related Illness*

It’s important to know how to recognize and help someone who is experiencing a *heat-related illness* [ [link removed] ].  Call 911 right away if you see these symptoms: high body temperature (103°F or higher), dizziness, nausea, passing out, headache, fast &strong pulse, confusion, and hot, red, dry, or damp skin.

Watch out for each other. Everyone should take precautions to prevent heat-related illness, but there are groups more vulnerable to heat. Check on those who are sick or have chronic conditions, older adults, pregnant people, children, those who live alone, pets, and outdoor workers and athletes.

“Heat causes more deaths in the U.S. annually than floods, storms, and lightning combined. Those most likely to get ill during the heat include older adults, young children, outdoor workers, athletes, and individuals with chronic medical conditions,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “Remember, your safety and the safety of others is crucial during extreme heat conditions. If you or someone around you experiences symptoms of heat stroke or heat exhaustion, such as dizziness, nausea, rapid heartbeat, confusion, or passing out, seek medical help immediately.”

The NWS HeatRisk takes into consideration:

* The duration of the heat including both daytime and nighttime temperatures
* If those temperatures pose an elevated risk of heat-related impacts based on data from the Center for Disease Control (CDC)
