Contra Costa County: Tips for preventing heat-related injuries:

Stay hydrated – Drink plenty of cool water and when possible, electrolyte drinks to replenish hydration. Do not wait until you are thirsty.
Limit sun exposure – When possible, stay in air conditioning on hot days. If you don’t have air conditioning, take cool showers or freeze a wet cloth to wipe down your head and neck.
Connect with your loved ones – Be sure to check on less mobile or older friends, family and neighbors who live alone, don’t have air conditioning or are hesitant to use their air conditioner.
Clothing – Wear lightweight, light-colored and loose-fitting clothing.
Avoid the hottest part of the day – If you have to be outside, try to stick to the cooler morning and evening hours. Wear light, loose clothing and take frequent, shaded or air-conditioned breaks. Do not exercise outside during the hottest part of the day.
Beware of hot cars – Never leave a person or a pet in a parked car, even for a short time. On a mild 80-degree day, the temperature inside a car can reach 100 degrees in fewer than 10 minutes.
Keep your pets cool – Give your pets plenty of fresh, clean water. Don’t exercise your pets in high temperatures or when the pavement is hot. Make sure they have a shady place to get out of the sun or bring them indoors.
Sunscreen – Protect your skin against cancer, burns and skin damage by using SPF 30 or higher.
Stay informed – Watch your local weather forecasts so you can plan outdoor activities safely and pay attention to any extreme heat alerts.
Take advantage of cooling spaces – utilize cooling spaces such as libraries or shopping centers, or cooling centers when available.
