Lambton Public Health (LPH) has extended a heat warning for the area due to hot and humid weather that's expected to continue through Wednesday.
The health unit said the extended warning, which was put in place because the heat warning went beyond two days, was issued by Medical Officer of Health Dr. Karalyn Dueck.
"This is also when vulnerable populations, including older adults, young children, people with chronic illnesses, pregnant individuals, people who work outdoors, and individuals who are underhoused or experiencing homelessness and are without access to air conditioning, are most at risk," read a media release.
Health Protection Supervisor Lori Lucas said in high temperatures and humidity, a person may not be able to cool properly which can lead to heat exhaustion or even heat stroke. She said the latter is a lot more severe.
"That involves the body temperature going really high, things like confusion and lack of coordination, dizziness and fainting as well," she said. "And then the thing that's different is that there's no sweating, and you have very hot, red skin."
Lucas said they work with a lot of community organizations that work with vulnerable populations to make sure that they're aware of the heat.
"Like social services, the shelters, Red Cross, seniors, that sort of thing, to say 'you might be more affected by these higher temperatures, so make sure that those individuals are aware of what they can do to keep themselves safe and healthy," said Lucas.
Individuals can protect themselves and others from heat related illnesses by drinking plenty of cool fluids, especially water, rescheduling or planning outdoor activities during cooler parts of the day, wearing loose-fitting, light-coloured clothing made of breathable fabric, taking a break by spending time in a cool place such as a community centre, shopping mall or public library, and by regularly checking in on neighbours, friends and other older family members.
