A return to frigid temperatures this weekend has prompted another Cold Weather Alert from the Middlesex London Health Unit.
The health unit says it will come into effect Saturday and last until Monday. It's expected the temperture will fall to -16 C on Saturday night and -17 C on Sunday night.
“With numerous popular events and celebrations occurring in the next couple of days, including Valentine’s Day, many people may have plans to spend time outdoors,” MLHU Environmental Health Manager David Pavletic. “It is important to not underestimate the risk of cold-related illnesses and injuries. If your plans involve being outdoors, please adjust them accordingly; and if you must be outside, protect yourself by dressing appropriately in multiple layers, covering exposed skin, and drinking warm fluids that are not caffeinated or alcoholic.”
Cold Weather Alerts are issued when temperatures are expected to drop to -15 C or lower or when windchill values are expected to make it feel like -20 C or lower.
The bone-chilling conditions could lead to cold-related injuries including frostbite, according to the health unit. 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 immersing it in warm, not hot, water. It can take up to 60 minutes to re-warm the frostbitten area.
The cold also increases the risk of hypothermia, which takes hold when a person’s internal body temperature drops below normal. 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.
