If you must be outside, wear loose fitting, light-colored clothing as light colors reflect rather than absorb heat.

Keep in mind the signs of heat exhaustion, which include dizziness, nausea, and feeling lightheaded.

Heat exhaustion can progress to heat stroke. Symptoms of heat stroke include confusion, nausea, dizziness, and potential loss of consciousness.

"It’s very important with this high heat. It’s not just thinking about yourselves, but your loved ones, your family members, especially the elderly or people who are on a lot of medications, who have lots of medical issues," said Dr. Trevor Lewis, chair of emergency medicine, Cook County Health. "The medicines can sometimes blunt the body’s response to getting rid of that heat and they can get into trouble quickly, so it’s a great time to really check on your neighbor."
