This from C-K Public Health:
Environment Canada has issued an extreme cold warning for Chatham-Kent. The current forecast is predicting wind chill values of minus 30°C to minus 35°C tonight through to Friday morning.
An extreme cold warning goes into effect when Environment Canada predicts a temperature or wind chill of minus 30°C or lower for at least two hours.
Overexposure to cold may result in hypothermia, which occurs when the body temperature drops below normal. Normal body temperature ranges from 36.1° to 37.8° Celsius (97° to 100° Fahrenheit). Symptoms of hypothermia may include pale skin, lethargy, confusion and hallucinations. In the initial stages, a person may shiver a lot, but as their body temperature drops shivering may also decrease.
In a severe case of hypothermia, a person becomes unconscious, their breathing is shallow, their pulse is irregular and hard to detect. If someone is found with these symptoms, immediate emergency medical treatment is necessary.
Symptoms of frostbite include:
- Areas of skin turning red, blue or a grey/white
- Pain, numbness and stiffness, especially in fingers, toes, ears and nose, which are most susceptible
If you suspect frostbite:
- Gently warm the affected skin or immerse in warm, not hot water.
- Don’t rub the area—re-warming may take 30-60 minutes.
- Seek emergency medical treatment for a severe, blistering case of frostbite
If you suspect someone may be suffering from hypothermia:
- Seek medical attention immediately.
- If possible, move the person to a warm area and dress them in warm clothing.
- Offer warm water, juice or milk.
- Do not offer alcohol or hot drinks (alcohol alters blood flow, making surface blood vessels open wider allowing the body to lose heat faster, providing a false sense of being warmer).
To avoid hypothermia or frostbite people are advised to:
- Dress warmly in layers—with warm gloves and boots.
- Wear a hat—30% of body heat escapes through the head.
- Drink plenty of fluids to avoid dehydration (remember that drinks containing caffeine can dehydrate).
- Alcohol consumption makes hypothermia more likely.
- Limit outdoor activity.
Remember not to leave pets outside for long either – they are at risk from the cold the same as people.
