• Avoid alcohol and caffeine in cold weather, as they can increase heat loss and risk of injury.
• Keep active to maintain circulation but avoid sweating excessively, which can cause chilling once you stop moving.
• Always check weather forecasts and plan outdoor activities carefully. If conditions are extreme or you feel unwell, seek shelter and medical help promptly.

Cold Weather Injury Prevention – Recognizing symptoms and danger signs

Cold Weather Injury Prevention starts with knowing how to spot symptoms early. Injuries from cold can range from mild to severe. Recognizing these signs helps you act safely and quickly.

Mild symptoms

• Redness or pale skin
• Tingling or numbness in fingers, toes, ears, or nose
• Cold, firm skin but no blistering
• Shivering or feeling very cold

At this stage, it is safe to warm the affected area slowly using body heat or warm (not hot) water. Avoid rubbing or applying direct heat like a heating pad.

Moderate symptoms

• Skin turns white, blue, or grey
• Swelling or blistering begins
• Loss of feeling or movement in the affected area
• Severe shivering or confusion

Do not try to rewarm the area if there is a chance it may refreeze. Seek urgent care at an emergency department or urgent care centre as soon as possible.

Severe symptoms and red flags

• Large blisters or blackened skin
• Severe pain or numbness that does not improve
• Signs of hypothermia: uncontrollable shivering, drowsiness, slurred speech, or loss of consciousness
• Rapid breathing or heartbeat

If you notice any of these signs, call 911 or your local emergency services immediately. These symptoms indicate a medical emergency that requires prompt professional treatment.

Immediate first aid steps for Cold Weather Injury Prevention

When dealing with cold weather injury prevention, acting quickly and safely is essential. You can take several practical steps at home or in the community to reduce harm while waiting for professional help.

Move to a warmer place

If you or someone else shows signs of cold injury, get out of the cold immediately. Find shelter indoors or in a protected area to stop further heat loss.

Remove wet clothing

Wet clothes increase heat loss. Carefully remove any wet garments and replace them with dry, warm layers or blankets. Avoid rubbing or massaging the skin, as this can cause damage.

Warm the affected areas gently

• Use body heat, such as placing hands in armpits or against warm skin.
• Apply warm (not hot) compresses or warm water (around 37-40°C) to affected areas.
• Do not use direct heat sources like heating pads, stoves, or fires to avoid burns.

Keep the person hydrated and awake

Offer warm, non-alcoholic, non-caffeinated fluids if the person is alert and able to swallow. Keep them awake and monitor their condition closely.

When to seek emergency help

• Call 911 if the person is unconscious, has difficulty breathing, or shows signs of severe hypothermia (shivering stops, confusion, slurred speech).
• Go to the emergency department or urgent care if blisters, numbness, or persistent pain develop after warming.
• Seek medical help if symptoms worsen or do not improve within a short time.

What NOT to do in Cold Weather Injury Prevention

When it comes to cold weather injury prevention, certain actions can make injuries worse or delay healing. Avoid these common mistakes to keep yourself and others safe.

Do NOT ignore symptoms

• Do not dismiss numbness, tingling, or persistent pain in fingers, toes, ears, or nose. These may be early signs of frostbite or hypothermia.
• Never wait to seek help if someone shows confusion, extreme shivering, slurred speech, or loss of coordination. Call 911 immediately in these cases.

Do NOT apply direct heat

• Avoid using hot water, heating pads, or open flames on cold injuries. Rapid warming can cause burns or worsen tissue damage.
• Do not rub or massage frostbitten skin. This can increase injury by damaging fragile tissues.

Do NOT consume alcohol or smoke

• Alcohol causes blood vessels to dilate, increasing heat loss and risk of hypothermia.
• Smoking reduces blood flow, which can worsen cold injuries and delay healing.

Do NOT remove wet clothing without preparation

Wet clothes increase heat loss. Remove them carefully and replace with dry, warm layers as soon as possible.

By avoiding these unsafe practices, you help protect yourself and others from serious harm during cold weather. Always prioritise safety and seek urgent care when symptoms worsen or do not improve.

Cold Weather Injury Prevention – When to call 911 or seek urgent care

Knowing when to call 911 or seek urgent care is vital for effective cold weather injury prevention. Some symptoms require immediate emergency help, while others can be managed by a family doctor or walk-in clinic.

Call 911 immediately if you notice:

• Signs of severe hypothermia, such as unconsciousness, very slow or irregular breathing, or no pulse
• Severe frostbite with blisters, blackened skin, or intense pain
• Confusion, inability to speak, or sudden weakness after cold exposure
• Severe difficulty breathing or chest pain
• Any injury with heavy bleeding that cannot be controlled

Go to the emergency department if you experience:

• Mild to moderate hypothermia symptoms like shivering, clumsiness, or drowsiness
• Frostbite without loss of consciousness but with persistent numbness or swelling
• Signs of infection in cold-related wounds, such as redness, warmth, or pus
• Severe pain or swelling after a fall or injury in cold weather

Visit a walk-in clinic or family doctor when:

• You have mild cold-related skin changes, such as redness or tingling
• You notice minor frostnip (early frostbite) with no blistering
• You want advice on preventing cold weather injuries in the future
• You have ongoing symptoms that do not improve after warming up

Always act conservatively and prioritize safety. When in doubt, seek emergency care promptly to prevent complications related to cold weather injury prevention.

Cold Weather Injury Prevention – Ongoing care and follow-up

After an initial cold weather injury, careful monitoring and self-care are essential to support healing and prevent complications. Keep the affected area warm and dry, but avoid direct heat sources like heating pads or open flames, which can cause burns. Gently rewarm the skin using warm (not hot) water if frostbite or freezing injury occurred.

Watch for delayed warning signs that may appear hours or days later. These include increasing pain, swelling, numbness, blisters, skin colour changes, or signs of infection such as redness, warmth, or pus. If any of these symptoms develop, seek medical advice promptly.

When to book follow-up with a doctor

• If symptoms do not improve within a few days
• If you notice worsening pain or skin changes
• If you have underlying health conditions like diabetes or circulation problems
• If you experience persistent numbness or loss of function in the affected area

For minor injuries, follow-up with your family doctor or a walk-in clinic is usually sufficient. However, if you experience severe pain, spreading redness, fever, or signs of tissue damage, go to urgent care or the emergency department immediately.

Remember, prevention is key. Practising cold weather injury prevention by dressing appropriately and limiting exposure helps reduce risks. Always prioritise safety and seek professional care when in doubt.
