Protect Yourself During Cold Temperatures
Extreme cold happens when temperatures drop below the average for that time of year. Exposure to cold temperatures can cause serious and sometimes even life-threatening health problems.
Who is at risk?
During extremely cold weather, everyone is at risk. However, some groups are more vulnerable than others:
- children and infants
 - seniors
 - homeless people
 - outdoor workers
 - skiers
 - ice skaters
 - people living in poorly insulated homes
 - people living in homes without power
 - people with asthma
 
What are the health effects of extreme cold?
Frostbite
- Frostbite usually affects the hands, legs, and fingers.
 - It can cause numbness, pain, swelling and blistering.
 - If you think frostbite has set in, don’t rub or massage the area. Instead, warm up the area slowly with warm compresses or your own body.
 - If toes or feet are frostbitten, try not to walk on them.
 
Hypothermia
- Hypothermia occurs when the body’s normal temperature is less than 35°C.
 - Symptoms may include:
    
- shivering
 - confusion
 - weakness
 - mumbling
 - low energy
 - pale skin colour
 
 - If you think someone has hypothermia, remove their wet clothing and bring them to a warm place. Warm the person gradually with several layers of blankets.
 
If you or someone you know experiences any of these symptoms, seek medical attention immediately.
What can you do?
- Cover exposed skin, which can become frostbitten in 30 seconds.
 - Wear a hat (you can lose up to 40% of your body heat through your head).
 - Wear gloves.
 - Wear a scarf to protect the chin, lips and cheeks.
 - Keep children indoors if the temperature falls below –25°C, or if the wind chill is –28°C or greater.
 - Drink warm fluids, avoiding caffeinated or alcoholised beverages.
 - Wear clothes in layers.
 - Find shelter from the wind to reduce wind exposure.
 - Listen to the weather forecast and plan ahead! If there is an extreme cold or wind chill warning, do what you can to stay inside.
