Chicago, the next few days are projected to have high temperatures in the 90s. Certain populations are more vulnerable to heat. Check out other heat preparedness tips and resources from CDPH at chi.gov/4opsdQQ
The image is a safety announcement from CDPH titled "Tips to Stay Safe in the Extreme Heat." It lists the following advice: drink water, stay indoors when possible and avoid strenuous activity, check up on neighbors and the elderly, and do not leave children or pets unsupervised in cars for any amount of time. The CDPH logo is at the bottom right.Red banner with white text states: "Populations that are more vulnerable to excessive heat include seniors over age 65, young children and pregnant people." Below, in black text on a yellow background, it advises to check on relatives and neighbors, seek shelter at city cooling centers if needed, and call 9-1-1 if acute symptoms occur. The bottom right features the CDPH logo with a red star.Know the signs of heat-related illness: nausea/vomiting, headache, intense sweating, dizziness or weakness, confusion, fainting.
