COLD WEATHER & Health Hazards for Risk Groups

Going outside during the wintertime may pose a health risk for certain groups. Being prepared and well informed, will reduce the risk of Frostnip, Frostbite or Hypothermia.


Groups that are more at Risk during Cold Weather conditions

  • Children younger  than 6 years of age
  • Elderly
  • People without permanent shelter or People in homes without power


When the temperature drops and the wind speed goes up, the exposed skin will experience a lower/colder temperature, this is the wind chill. For example, if the outside temperature is -10
ºC and the wind chill is -20, it means that your face will feel as cold as it would on a calm day when the temperature is -20ºC.

Exposed skin will freeze in minutes at very cold wind chills. It is advised to dress warmly and to limit your outdoor time accordingly.
