Recognizing cold‑related health risks

Frostbite
Look for numbness, white or yellowish skin, and a hard or waxy texture. Severe frostbite can cause nerve damage and, in extreme cases, lead to amputation.

Hypothermia

This occurs when body temperature drops too low. Watch for shivering, confusion, slurred speech, and loss of coordination. Seek medical attention immediately if these symptoms appear.

Heart attack risk

Cold temperatures reduce blood circulation and increase heart strain. Individuals with cardiovascular conditions should speak with their doctor about winter safety. Seek urgent care for chest pain, shortness of breath, or weakness.

A safer winter starts with preparation

Winter is part of life in Canada, but respecting its unpredictability can help you enjoy the season safely. With the right preparation and awareness, you can protect yourself and others from the dangers of extreme cold.
