Explaining the ‘heat dome’ and hot-weather health risks
People in Southern Ontario and Southern Co back or getting ready for a hot and muggy weekend and in some parts of your record, breaker temperatures in southern Ontario are set to soar into the mid-thirties tomorrow and stay there with the humidex. It’S a did the feel more. Like the mid-forties and then come back this morning, warnings are in place in and around the Montreal area. Let’S check in with Chris Murphy Now The Weather Network. He has more on what we can expect Ava’s coming and we have a heat Dome to think what the heck we’re talking about. High pressure in the upper atmosphere in acts like a cap or dumb and that traps, and that can promote a heatwave and that’s what’s going to happen Friday and Saturday, particularly that’s all desert heat in Arizona, have been over a hundred and fifty degrees Fahrenheit by the Heat and humidity has been earlier this week. Let me show you some examples and Friday and Saturday. Those are the critical days. Windsor mid-thirties feeling like 47 for things, are to settle down back to seasonal next week, Toronto, Friday and Saturday 33 degree temp, the humidex in the mid-forties and Montreal low 30 temperatures low 40 humidex, so bottom line. Is you want to find lots of really setting an across the country we’ve invited a doctor on the show today to talk about the health risks of those high temperatures? Dr. David Kiser joins us from our studio in Montreal today, where that heat wave is hitting and he’s a public health special at Montreal Public Health Department. Welcome. Thank you for joining us up a health perspective. What’S the biggest concern as a doctor during a heatwave, the Heat and those include the elderly, but it also includes people with some chronic diseases that are very common like diabetes or heart. Disease or lung diseases include people with some mental health issues, especially people are taking medications for gout schizophrenia and obviously includes the very young, and we know that children, the age of four, are less able to express the thirst, for example, or two to recognize this. But that’s really what what is of concern to US during a heatwave, because we know that those people, especially when there’s a couple of days or right now we have a forecast of about 3 days of hot weather during the day and hot weather at night. We know that those people have more difficulty dealing with. Let’S talk about the hot weather at night. That is because it continues on into the night that some of the dangerous he could correct pack, some heat one of them. I think we we kind of recognizes heat stroke right so marathon, runner, a hot day gets dehydrated, the body overheats and that’s really dangerous medical emergency, but thankfully quite rare and really isn’t what we’re talkin about dinner of of heat like we have right now. What happens to people with chronic diseases or the elderly is that they get slowly dehydrated and it kind of just the heat exhaust the body’s capacity to deal with that, and that’s why people get sick and and people can die, and one of the really important issues Is how hot is it at night, because you have a hot date with with the high humidity, but if the temperature goes down to normal temperature between 12 and 15 in a lot of our cities and people get a break from the Heat, and that risk is Much less, but in the next few days what we have is temperatures that are projected to be 20 21 22 degrees at night, and so people aren’t getting a break any in apartment buildings, for example, or in the middle of big cities. They can be quite a lot hotter than that indoors, because everybody has experienced that the fact that when you have a hot day that he stays for a long time inside a building temperature 2730 weeks measuring a 35-40 inside buildings at night. And that’s where there’s really a big risk for people also, because they’re more likely to be alone at home and not have the help that they might have during the day if they have symptoms some of the symptoms. Some of the signs from someone experiencing too much heat symptoms and signs are really for for severe heat. Stroke are dry skin confusion. People can lose. You call 911 for people who are experiencing stress or who are experiencing more slow impact of heat during a. Of several days of hot weather. Are not that specific. Often it’s are related to dehydration, so can be feeling lethargic feeling tired of not having much energy, but there aren’t necessarily clear clear, a signs and that’s why. I think the important part is prevention, so 1 drinking water regularly and then getting a break from the heat. Is really the messages we put out there, but the second thing is to the extent that people have family friends neighbors around that are checking on them any kind of chain. The worst – and somebody who we know is vulnerable should be taken care of, because there aren’t necessarily dramatic signs before people really become at risk for more serious impacts, practical things people can do so. I think they’re really important message started starting out to the people are most at risk. Maybe those who are are least able to kind of follow the suggestion that we give them alone at home may be elderly who may be less mobile. They need help to get out of the heat at least a couple of hours a day. They may need help to remember to drink water regularly. What we’re looking at it and there’s some research studies going on right now is. Is it practical tips? Is one of the best ways that people who don’t necessarily back to the air conditioning or who can’t easily get out to a cool place so cool themselves? But I think there’s there’s something we can recommend taking a cool bath or a cool shower a couple times. A day. Just allows the body to get the heat out. Second thing is: if you have a fan, when it’s really really hot and humid a fan, doesn’t do the same thing as an air conditioner quit putting a frozen water bottle in front of a fan. For example, some cool air blowing through the third thing is just a cool washcloth. So again, that idea is that putting that on the skin allows the body to get heat transfer, heat away from the body and so cool washcloth on the on the forehead or on different parts of the body several times a day as often as needed. Those are some easy things that people who don’t necessarily have access to it, so other things can can do some really good advice. Call Public Health Department in Montreal. Thanks for your time,
