The average number of extreme heat days per year in Alameda County (hotter than 92.6℉) is expected to increase from 5 to as many as 15 by 2050. A 2017 study by the Public Health Department identified the Eden Area communities of Ashland, Cherryland, and Hayward Acres as areas with high vulnerability to the impact of increased heat.

The Cooling Our Communities Heat Preparedness Program built upon strong partnerships between the CDA Planning Department, GSA Sustainability Office, and the Public Health Department to assess vulnerability to extreme heat and connect Eden Area residents to cooling strategies and community capacity building efforts to help them stay cool as the climate warms.

Drink water throughout the day and evening. Avoid drinking alcohol and caffeine. Avoid large meals. Instead, snack periodically throughout the day and eat smaller meals frequently.

Stay Cool

Cooling down the whole body is important for reducing the effects of heat. This can be done by taking a cool bath or placing cold, damp towels over the body. For maximum cooling, place cold towels over the hands, face, and feet. At night, make sure to use light sheets and sleep as low to the ground as possible, allowing time for the body to recover from daytime heat.

Stay Informed

Sign up for the AC Alert mass notification system, a free service that issues notifications about potential safety hazards by voice, text, and/or e-mail (you choose the notification method when you sign up.) All information you provide is kept strictly confidential and you can choose to stop at any time.

Create a Cool Environment

Close curtains to reduce the amount of heat passing through the home. Keep electric lights down throughout the day. When cooking, avoid using the oven and opt for the microwave instead.

Use the Buddy System

Make sure family and friends are preparing for the next heat wave and create a buddy system to look after one another.

Dress Smart

Wear light-colored, lightweight, and loose-fitting clothing. Open shoes with circulation also help to cool the body. During the hottest times of the day, avoid strenuous activity and stay inside or visit an accessible cooling center nearby.
