Peterborough Public Health Extends Frostbite Alert to January 1

December 29, 2017 – Alert Covers the City and County of Peterborough and Curve Lake and Hiawatha First Nations

Peterborough Public Health is extending the Frostbite Alert issued December 26, 2017 because of forecasted nightly wind chill values of -27°C or lower from December 29, 2017 to January 1, 2018.  Temperatures are expected to rise above the Frostbite Alert level during the day of January 1, 2018.

Extreme cold events are a potentially significant health risk and can have a severe impact on the health of vulnerable populations including infants, the elderly, people with circulatory problems, and the marginally housed.  Local social service agencies rely on Peterborough Public Health frostbite alerts to determine if services should be extended or enhanced.

In order to protect the health of people in Peterborough County and City and Curve Lake and Hiawatha First Nations, Peterborough Public Health advises local residents to take the following precautions:

  • Check face and extremities frequently for signs of frostbite. Exposed skin can freeze in as little as 10 to 30 minutes.
  • Consider re-scheduling outdoor recreational activities, especially during the evening.  There is a serious risk of hypothermia and frostbite if outdoors for long periods.
  • Use caution when shoveling snow especially for those that have heart, respiratory (breathing) problems or other medical conditions. Snow shoveling is strenuous and can cause an onset of heart or respiratory problems.
  • Check on the elderly or people with disabilities living alone.

What clothing should be worn outdoors?

Always wear clothing appropriate for the weather. Synthetic and wool fabrics provide better insulation.  Some synthetic fabrics are designed to keep perspiration away from your body which keep you dry and further reduce your risk.

Here are some useful tips:

  • Dress in layers with a wind resistant outer layer. You can remove layers if you get too warm (before you start sweating) or add a layer if you get cold.
  • Wear warm socks, gloves, a hat and scarf in cold weather. Be sure to cover your nose to protect it.
  • If you get wet, change into dry clothing as soon as possible. You lose heat faster when you’re wet.

Cold related illnesses include:

Symptoms/signs include: shivering, exhaustion, confusion, fumbling/uncoordinated movements, memory loss, slurred speech, drowsiness.


Symptoms/signs include: white/greyish skin area, skin that feels unusually firm or waxy, or numbness.

Increases in other health problems can also be seen, especially for those with other chronic medical conditions such as heart conditions.

When the weather gets this cold, please check in on others like the elderly to make sure they are staying warm enough.  If you must go outside, do dress appropriately by covering up as much as possible as frostbite can develop very quickly on exposed skin during periods of extreme cold. Wear waterproof and windproof outer layers, as brightly coloured as possible if you’re going to be out in the snow, and choose warm mittens instead of gloves.  Avoid getting wet and change into dry clothing as soon as possible if you do get wet from precipitation, sweat or from falling in water.
