The Will County Emergency Management Agency is advising residents to take precautions and to utilize cooling centers if needed.

• Heat Cramp Symptoms: Painful muscle cramps/spasms usually in legs and abdomen; heavy sweating.

Residents should also be aware of the following tips during periods of high temperatures:

• Wear light-colored, loose-fitting, and lightweight clothing.
• Ensure children are wearing appropriate clothing and avoiding long periods of time outdoors.
• Avoid strenuous activity outdoors.
• Fans will move air around, but do not lower your temperature.
• Use air conditioning inside your home or visit an air-conditioned location.
• Check in with relatives and neighbors on if they have access to air conditioning.
• Never leave children or pets in a vehicle unattended.

Outdoor work should be minimized during extreme heat and employers are recommended to avoid heavy-duty outdoor projects during a Heat Advisory. For anyone working outdoors during extreme heat, the National Safety Council recommends the following preventative measures:

• Eat light. The more calories you take in, the more body heat you produce.
• Drink plenty of fluids before work and throughout the day. Avoid caffeine.
• Wear lightweight clothing. Wide brimmed hats protect workers from direct sunlight.

Residents should also be aware of the cooling centers available in almost every community in the county, including in village halls, fire stations, libraries, and other public meeting sites.
