The National Weather Service has issued a heat advisory for all of central and southeast Illinois. This advisory went into effect at 1:45 PM Monday and is currently set to remain in effect until midnight Friday.

Residents of the affected areas will see heat index values of 105 to 110 degrees. The collective effect of this prolonged heat will pose a serious risk to the health of the public. Prolonged exposure to this level of heat can cause serious illness such as heat exhaustion and heat stroke.

Signs of heat exhaustion may include heavy sweating, weakness, dizziness, nausea, headache, and a fast heartbeat. If untreated, heat exhaustion can progress into heat stroke, which is a medical emergency marked by confusion, loss of consciousness, seizures, or a dangerously high body temperature.

To help prevent heat-related illness, stay hydrated, take frequent breaks in cool or shaded areas, avoid strenuous activity during the hottest parts of the day, wear lightweight clothing, and never leave children or pets in a hot vehicle. If someone shows signs of heat stroke, call for emergency help immediately and move them to a cooler area while providing any emergency assistance.

Health officials urge residents to drink plenty of fluids, stay in air-conditioned spaces, refrain from direct sunlight exposure, and be sure to check in on your friends, family, and neighbors. Individuals who are outdoors or stuck in a non-air-conditioned space should seek shade or, if possible, move to a place where air conditioning is provided.

If your home does not have air conditioning, many communities have local facilities you can visit to get some time out of the heat. Contact your local non-emergency phone number or follow local media for specific locations.
