SIMCOE, July 19, 2019 – With high temperatures expected to continue, the Medical Officer of Health is issuing a Heat Warning for the residents and visitors of Haldimand and Norfolk counties. Hot and humid conditions are expected throughout the day. The HNHU recommends that persons take steps to prevent heat-related illness. A list of local services offering a place to cool down can be found


All people can experience adverse health effects from extreme heat. However, older residents and children are particularly vulnerable.  As well, individuals with heart problems, breathing difficulties and psychiatric conditions as well as those who may be socially isolated (e.g. low income earners, homeless) are greater risk. Check on friends, family and neighbours frequently during heat events to make sure they are cool and hydrated.


The HNHU recommends taking the following actions to stay cool:

  • Stay indoors in an air conditioned environment.
  • 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 sun out by closing awnings, curtains or blinds during the day.
  • If you must be outdoors, avoid sun exposure by staying in the shade; wear a wide-brimmed, breathable hat or use an umbrella.
  • Plan outdoor activities during cooler parts of the day (the early morning or in the evening).
  • Never leave people or pets in your care inside a parked vehicle or in direct sunlight.
