For the second weekend in a row, bone-chilling conditions have prompted the Middlesex London Health Unit to issue a Cold Weather Alert.
The combination of brisk winds and freezing temperatures will see the overnight low Friday plunge to -18 C, but feel more like -26 C.
“Whether it’s a Knights game at Budweiser Gardens, or enjoying all Richmond Row has to offer with friends, Friday nights tend to be when many people spend some time outdoors; and dressing warmly isn’t often the first thing on their minds,” said Randy Walker, public health inspector with the Middlesex-London Health Unit. “We want people to think about their health first, so even if you’re only outside for a few minutes don’t take any chances. Make sure to dress in layers and that any exposed skin is covered to prevent frostbite.”
The alert will end Saturday morning when temperatures rise slightly. However, public health officials note with a below average daytime high of -10 C and the windchill, those venturing out will still need to bundle up.
Skin overexposed to the cold is at risk of frostbite when the temperature drops below the freezing mark. Symptoms include skin turning red, blue, or in later stages, a grey/white colour. Anyone who suspects they have frostbite is advised not to rub the affected area but to warm it by placing it next to warmer skin or immerse in warm, not hot, water. It can take up to 60 minutes to re-warm the frostbitten area.
The extreme cold also increases the risk of hypothermia, which takes hold when a person’s internal body temperature drops below normal. According to the health unit, symptoms can include pale skin, drowsiness, confusion, and hallucinations. Severe cases can cause a loss of consciousness, shallow breathing, and a hard to detect pulse. Anyone exhibiting these symptoms should be taken for immediate medical treatment.
Health officials are also advising agencies that assist London’s homeless population to prepare for an increase in demand for services. Anyone who spots someone who is outdoors and in distress due to the cold is urged to call London CAReS at 519-667-2273 or 9-1-1 if it is a medical emergency.
