Determine if you or others around you are at greater risk of heat illness. Check on older adults, those living alone and other at-risk people in-person or on the phone multiple times a day.&#8221; <\/p>\n<p class=\"c-paragraph\">Wednesday will see a daytime high of 33 C with a chance of showers. The temperature will dip down to 31 C on Thursday and 28 C on Friday. <\/p>\n<p class=\"c-paragraph\">\u201cWatch for the early signs of heat exhaustion in yourself and others. Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. Stop your activity and drink water,\u201d the national weather agency wrote. <\/p>\n<p class=\"c-paragraph\">\u201cDrink water often and before you feel thirsty to replace fluids.\u201d <\/p>\n<p>Heat stroke \u2018a medical emergency\u2019<\/p>\n<p class=\"c-paragraph\">Speaking to CP24 on Monday, Dr. Allan Grill, Chief of Family Medicine at Markham Stouffville Hospital, outlined the stages and symptoms of heat-related illness. <\/p>\n<p class=\"c-paragraph\">\u201cIf you aren\u2019t keeping well-hydrated&#8230; the first thing that happens is get these heat cramps,\u201d he said. \u201cYou get a lot of muscle cramps all over the body, you feel really achy.\u201d <\/p>\n<p class=\"c-paragraph\">He noted that without intervention, it will progress to what is known as \u201cheat exhaustion.\u201d <\/p>\n<p class=\"c-paragraph\">\u201cWhat happens is people get weak and dizzy because their blood pressure drops, they tend to get headaches and sometimes they can even start to vomit and that unfortunately makes you even more dehydrated,\u201d Grill noted. <\/p>\n<p class=\"c-paragraph\">\u201cIf you start to see those signs or symptoms, get that person into a cool place, use some cold compresses like a cold washcloth on their skin, give them something to drink.\u201d <\/p>\n<p class=\"c-paragraph\">He noted that if the illness advances even further, it becomes a medical emergency. <\/p>\n<p class=\"c-paragraph\">\u201cUnfortunately, if you ignore the first two, you can end up with something called heat stroke. Heat stroke is when the body temperature goes above 40 degrees, your body loses its ability to sweat so you can\u2019t cool off, people have a decreased level of consciousness,\u201d he said, adding that a call to 911 is necessary at this stage. <\/p>\n<p class=\"c-paragraph\">\u201cGet them medical care immediately,\u201d he said. <\/p>\n","protected":false},"excerpt":{"rendered":"Environment Canada is calling for a high of 33 C on Monday, feeling closer to 38 with the&hellip;\n","protected":false},"author":2,"featured_media":799567,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[194291],"tags":[712,49,48,3302],"class_list":["post-799566","post","type-post","status-publish","format-standard","has-post-thumbnail","category-toronto","tag-apple-news","tag-ca","tag-canada","tag-toronto"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/799566","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=799566"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/799566\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/799567"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=799566"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=799566"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=799566"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
