Environment and Climate Change Canada has issued a heat warning for Durham area beginning May 25.
A heat warning occurs when the forecast conditions include a daytime high of at least 31°C and overnight temperatures of 20°C or greater, or with Humidex values of at least 40 for two or more days.
Meanwhile, Durham Region Health Department said it will begin monitoring temperature conditions as part of the Durham Region Heat Warning Information System for the 2020 summer season.
Throughout the summer, the Health Department will be posting information an durham.ca/heat to inform residents of conditions that indicate a heat warning will be issued and will also use the Health Department social media channels to provide updates at www.twitter.com/DurhamHealth and www.facebook.com/durhamregionhealth.
“The Health Department will maintain our ongoing communication process with the various community groups and agencies that provide support to vulnerable populations,” said Sendi Struna, Manager, Health Protection with Durham Region Health Department. “We will continue to work with these community groups to issue advanced notices to ensure they have the information necessary to support individuals who may need assistance. We also encourage everyone to check the website and follow us on social media to stay informed and updated and take the necessary precautions to protect yourself from heat-related health concerns.”
Take precautions
When heat warnings are issued, the Health Department advises area residents to take precautions to prevent heat-related illness during the upcoming heat warning.
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, said a Health Department statement.
Heat illnesses are preventable; however, these illnesses can lead to long-term health problems and even death. If any symptoms of heat illness are present, such as dizziness or fainting, nausea or vomiting, headache, rapid breathing and heartbeat, or extreme thirst, immediately move to a cool place and drink liquids, especially water.
The most dangerous heat illness is heat stroke with symptoms that include complete or partial loss of consciousness, or confusion and high body temperature. If caring for someone with these symptoms, call 911 immediately.
Everyone is encouraged to stay alert and take precautions. Remember to frequently check in on neighbours, friends and older family members, especially those who are chronically ill, to ensure that they are cool and hydrated. It’s best to call, text or video-conference. If that is not possible, be sure to practice physical distancing.
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.
