Watch out for older adults, infants and young children, those dealing with chronic illness or taking certain medications and those who work outdoors. Spokesperson for Parkland Ambulance, Lyle Karasiuk, says these are the people most at risk during extreme heat. People taking blood pressure or fluid build-up medications should be cautious if spending any amount of time in the heat. Karasiuk explains that blood pressure medication can affect how your body regulates heat. Fluid build-up medication means you are already losing fluid because of what you are taking, but in the heat you will be sweating more, meaning losing more fluids. He suggests contacting your pharmacy, your health care provider or calling 811 if you have concerns about your medication causing issues in the heat. Karasiuk adds that if you know someone who may be at risk, keep in touch with them to make sure they are okay.

The signs for heat stroke and heat exhaustion have some similarities, but there are differences. For heat stroke, the symptoms are being light-headed, dizzy, confused, a high temperature and not sweating but the skin is hot to the touch. Some of the signs for heat exhaustion are headache, skin rash, nausea or vomiting, dizziness, extreme thirst and dark urine. If you notice these signs, bring the person to a cool place and have them drink water. If the signs for heat exhaustion persist, call 911.
