Health Unit Issues Heat Warning for the Upcoming Weekend



Friday July 19, 2019


Perth County  ̶  The Perth District Health Unit is issuing a heat warning for Perth County for today and the upcoming weekend. Temperatures and humidex levels are expected to be extreme starting today, Friday, July 19, and lasting through to Sunday, July 21.


The Health Unit issues a heat warning when temperatures are expected to reach a daytime high of 31°C or higher with a minimum daytime low of 20°C or a Humidex of 40 or higher, for two consecutive days.


The Health Unit is reminding people to take care to prevent heat-related illnesses. Extreme heat can cause dehydration, heat exhaustion, heat stroke and even death. Seniors, infants and young children, and people with chronic illness or who take certain medications are at a greater risk of suffering from heat-related illness.


Staying safe during a heat wave is a community’s responsibility: be sure to check on your family, friends and neighbours whose health may be at risk during a heat warning.


During a heat warning, residents and visitors should:

  • Drink plenty of cool liquids, especially water
  • Avoid outdoor activities during the hottest times of the day; reschedule or plan them for the cooler times of the day
  • Wear loose fitting, light-coloured clothing made of breathable fabric
  • Never leave people or pets inside a parked vehicle or in direct sunlight
  • Take a break from the heat by spending a few hours in a cool place, such as a tree-shaded area, swimming facility, or an air conditioned spot, such as a public building, shopping mall, grocery store, or public library
  • Take cool showers or baths until you feel refreshed
  • Prepare meals that don’t need to be cooked in your oven
  • Block sun out by closing curtains or blinds during the day
  • Avoid sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat or by using an umbrella.
