With another few steamy days ahead of us, the Chatham-Kent Public Health Unit has extended its heat warning.

Officials say with increased heat and humidity, your body may not be able to cool properly, which can lead to heat exhaustion or even heat stroke.

Symptoms of heat-related illness may include: rapid breathing, dizziness or fainting, vomiting, and extreme thirst, among other things.

Extended heat warnings are issued when there are three or more days of daytime high temperatures higher than 31 Celsius, and nighttime lows higher than 21.

A cold front is expected to move into the region at some point tomorrow, bringing sme relief and more seasonal temperatures.
