Caution is being urged as heat warnings have been issued for the Chapleau and Gogama areas.
Environment Canada says daytime temperatures for Chapleau, Gogama, Foleyet, and Missinaibi Lake will be near or above thirty degrees until the weekend, with temperatures only dropping to the high teens overnight - a cooler airmass is expected to bring relief Saturday.
Public Health Sudbury and Districts warns the heat can lead to heat stroke, heat exhaustion, fainting, heat rash, heat cramps, and more issues, with older adults, young children, pregnant women, people with chronic illnesses, alcohol or drug users, the homeless, and those working or exercising in the heat most at risk.
To deal with the heat, the health unit recommends wearing loose-fitting light-coloured clothing made of breathable fabric, drinking plenty of liquids, seeking shade, and taking breaks from the heat.
