News Release

Extended heat warning terminated

WHITBY, ON September 27, 2017 - The Health Department is advising Durham Region residents that the extended heat warning issued Sept. 24 is now terminated. The Health Department will continue to monitor information received from Environment Canada and will provide updates, as necessary, to area residents.

During the extended heat warning, the Health Department advised area residents to take precautions to prevent heat-related illness. While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for older adults, infants and young children, people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses, people who work or who exercise in the heat, homeless people and low-income earners. Those who take medication or have a health condition should ask their doctor or pharmacist if these medications can increase their health risk in the heat and follow the appropriate recommendations.

To help avoid heat-related illnesses, residents are encouraged to take the following precautions to beat the heat and stay cool:

  • Drink plenty of cool liquids, especially water, before feeling thirsty.
  • Wear loose-fitting, light-coloured clothing made of breathable fabric.
  • Take cool showers or baths until you feel refreshed.
  • Take a break from the heat by spending a few hours in a cool place.
  • Block out the sun by opening awnings, and closing curtains or blinds during the day.
  • Avoid sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat or using an umbrella.
  • Reschedule or plan outdoor activities during cooler parts of the day.
  • Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
