Niagara residents are advised to take extra precautions during episodes of extreme heat and humidity.

Some steps to minimize heat related illness include drinking plenty of fluids, and if you have to be outside, plan your activities during cooler parts of the day.
 Any health condition that causes dehydration makes the body more susceptible to heat sickness. Consult your doctor if you feel signs of confusion, dizziness, nausea, muscle swelling, heart disturbances, and/or a headache.
