Cold Weather Alerts
Residents of Lambton County should take precautions during cold weather alerts. The public is urged to listen to local weather forecasts and to pay particular attention to Environment Canada’s wind chill index for updates.
Overexposure to cold may result in hypothermia, which occurs when a person’s body temperature drops below normal. Normal body temperature ranges from 36.1 to 37.8 degrees Celsius (97 to 100 degrees 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 to prevent coma or death.
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, causing surface blood vessels to open, allowing the body to lose heat faster, creating a false sense of being warmer).
To avoid hypothermia or frostbite people should:
- Dress warmly and in layers.
- Wear a hat – up to 50% of body heat escapes through the head.
- Drink plenty of fluids to avoid dehydration (remember that drinks containing caffeine can dehydrate).
- Avoid alcohol.
- Limit outdoor activity.
- Stay dry – wet clothing chills the body; remove outer layers or open your coat if sweating.
- Know your limits – children, the elderly and those with circulation problems are more susceptible to the cold.
Symptoms of frostbite include:
- Skin turning red, blue or a gray/white.
- Pain, numbness and stiffness, especially in fingers, toes, ears and nose which are most susceptible.
If you suspect frostbite:
- Warm the skin next to the affected area or immerse in warm water (not hot).
- Don’t rub the area. Re-warming may take 30-60 minutes.
- Seek emergency medical treatment for a severe, blistering case of frostbite.
