Nhiệt độ cực cao có thể rất nguy hiểm. Hãy tìm hiểu các triệu chứng say nắng, kiệt sức vì nóng và cách chuẩn bị cho mùa nắng nóng để bảo vệ sức khỏe của quý vị và những người hàng xóm, bạn bè và gia đình quý vị.
Những người có rủi ro nhiều hơn
Người khác nhau phản ứng khác nhau với nhiệt và một số người có rủi ro bị ảnh hưởng đến sức khỏe nhiều hơn. Giữ mát đặc biệt quan trọng đối với các nhóm người sau:
- người lớn tuổi, từ 60 tuổi trở lên
- những người sống một mình
- những người có bệnh trạng từ trước như tiểu đường (diabetes: tiểu đường), bệnh tim (heart disease: bệnh tim) hoặc bệnh hô hấp (respiratory disease: bệnh hô hấp)
- những người bị bệnh tâm thần như tâm thần phân liệt (schizophrenia: tâm thần phân liệt), trầm cảm hoặc lo lắng
- những người bị rối loạn sử dụng chất kích thích, bao gồm cả bia rượu
- những người bị hạn chế khả năng vận động
- những người bị bỏ bê về nơi cư trú
- những người làm việc trong môi trường nóng
- những người đang mang thai
- trẻ sơ sinh và trẻ nhỏ
Những người khác cũng có thể bị ảnh hưởng bởi nhiệt. Mọi người phản ứng khác nhau, vì vậy hãy lắng nghe cơ thể của quý vị.

Thường xuyên kiểm tra hàng xóm, bạn bè và gia đình quý vị để bảo đảm họ có thể giữ mát và có kế hoạch sẵn sàng. Việc này có thể cứu mạng sống.
Trong các sự kiện đợt nóng trước đó, một tỷ lệ lớn nạn nhân chết ở nhà và bị cô lập về mặt xã hội.
Khung hỗ trợ kiểm tra Nhiệt của VCH cho các tổ chức phi chính phủ
Vào mùa xuân năm 2022, nhóm Môi trường Lành mạnh VCH đã tham gia với chính quyền địa phương và các tổ chức cộng đồng để tìm hiểu những gì họ cần biết nhằm giúp họ tiến hành kiểm tra nhiệt để hỗ trợ các thành viên cộng đồng. Các đối tác đã xác định nhu cầu về thông tin về cách thực hiện việc kiểm tra và trả lời các câu hỏi thường gặp giữa nhân viên và người được kiểm tra. Việc kiểm tra an toàn nhiệt diễn ra trong nhiều môi trường khác nhau và do nhân viên hoặc tình nguyện viên được đào tạo đa dạng thực hiện. Với bối cảnh rộng, khung này được tạo ra để các tổ chức có thể chọn thông tin phù hợp nhất với môi trường của họ nhằm phát triển những kế hoạch kiểm tra cho tổ chức riêng của họ.
Tải xuống khung hỗ trợ kiểm tra nhiệtSteps to protect yourself and others from heat
The most dangerous aspect of heat waves for most people is high indoor temperatures. Spending time in a cool space and drinking plenty of water is the best way to prevent heat-related illnesses.
Wildfire smoke can also cause health problems. During both wildfire smoke and heat events, consider also filtering your air using HEPA air cleaners. Find out more about wildfire smoke.
-
Keep yourself and other people cool
- Spend time in cooler indoor and outdoor spaces (i.e. community center, library or mall with air conditioning).
- Drink plenty of water and other liquids to stay hydrated, even if you do not feel thirsty.
- Cool off with a shower, bath or soaking part of your body in water.
- Wear a wet shirt or damp towels to cool down.
- Wear loose, light-coloured, breathable clothing.
- Limit activity, especially during the hottest hours of the day (generally 2 p.m. to 4 p.m. in B.C.).
- Watch for signs of heat exhaustion and heat stroke. For heat-vulnerable people, the risk for heat-related illness may increase at indoor temperatures over 26°C (78 °F) and may be very high at indoor temperatures over 31°C (88 °F).
-
Keep spaces cool
- During the day, close windows and shades/blinds to trap cooler air inside and block the sun.
- At night, open windows and doors when it is cooler outside (usually 9-10 p.m. in B.C.). Some bathroom and kitchen fans vent outside and can be used to remove warmer indoor air. Use portable fans to bring cool air into the home overnight.
- Consider getting an air conditioner for your home. If you have air conditioning, be sure to turn it on.
- Monitor indoor temperatures for yourself and those you are checking on. For heat-vulnerable people, the risk for heat-related illness may increase at indoor temperatures over 26°C (78 °F).
How to check-in and support others during hot weather
Checking in with someone during a heat wave can save lives. A heat check-in is a visit, call, or text to assess the heat-related safety of the home, if the person shows signs of heat-related illness, and if they need help. Anyone can do a heat check-in and health training is not required.
NCCEH guide: How to check in with people during a heat wave
Use this guide from the National Collaborating Centre for Environmental Health (NCCEH) to check in with family, friends, neighbours and other community members who may be at higher risk for heat illness. Available for download in English, French, Chinese and Punjabi.
VCH guide for community organizations checking in with people during heat waves
Heat check-ins happen in a variety of settings and are carried out by organizational staff or volunteers with diverse training. This framework was created so organizations may select the information that is most relevant to their setting to develop their own organizational heat check-in plans.

Heat check-in: Train the trainer (video)
This train-the-trainer video resource is for organizations training their staff or volunteers to do heat check-ins.
Cooling centres and cooling spaces
Local weather, shelter, and emergency information
During extreme heat events, it is important to spend time in cool spaces. Several cities and towns in the Vancouver Coastal Health (VCH) region operate specialized cooling centres or encourage people to use other public spaces to cool down (like libraries, community centres and parks). Misting and water fill station stations may also be provided during a heat event.
Creating cooling spaces during hot weather
Evidence-informed public health guidance for community organizations to set up and operate inclusive, acceptable, and effective cool spaces in a variety of facilities.
Policy tools to create and support cooler, safer indoor living spaces
Vancouver Coastal Health (VCH) conducted a review of policy and regulatory options that could increase thermal safety in homes within the VCH health region. In addition to describing a variety of policy options, findings indicate that multiple policy interventions at different levels of government are needed, as are strategies to overcome significant challenges relating to cost and feasibility, and to avoid unintended consequences.
“Heat Warnings” and “Extreme Heat Emergencies”
In response to the 2021 BC heat dome, multiple health sector partners, and Environment and Climate Change Canada (ECCC) developed the BC Heat Alert and Response System (BC HARS). This two-level alert system lays out the criteria that ECCC will use to declare a Heat Warning (Level 1) or an Extreme Heat Emergency (Level 2), the appropriate public health messaging for both types of alerts, and the recommended actions for the health sector, local governments, and other partners.
Read more about the BC HARS on the BCCDC website.
Alerts
-
Heat Warning (Level 1)
Threat: Daytime and overnight temperatures are higher than seasonal norms and holding steady.
Action: Take the usual steps to stay cool and check on people at higher risk from heat. -
Extreme Heat Emergency (Level 2)
Threat: Daytime and overnight temperatures are higher than seasonal norms and getting hotter every day.
Action: Activate your emergency plan and check on people at higher risk from heat at least once a day.
Special considerations for mental health and substance use
For many, extreme weather can take a toll on mental health and well-being. Challenges with substance use can increase, and substance use can place people at high risk for heat-related illness. Don’t hesitate to get help when you need it. There are supports available.

Extreme heat research and data
Vancouver’s Indoor HEAT Study (2021-2023)
This multi-year Indoor HEAT Study collected indoor air temperature, building, and household data from Vancouver residents to better understand indoor heat exposure and inform recommendations for keeping homes safely cool.
2021 BC heat dome and VCH ER visits
Following the 2021 BC heat dome, the VCH Public Health Surveillance Unit studied emergency room visit data in collaboration with VCH and Providence Health Care Emergency Medicine programs. This event led to a substantial increase in Emergency Department visits related to heat-related illness in VCH hospitals. These visit rates varied significantly by area of residence and age.
Coming soon: VCH CLEAR Report
The Climate, Lived Experience, And Resilience (“CLEAR”) Community Consultation Report recognizes the unique knowledge and insights of people with lived experience of climate-related events. CLEAR has been an ongoing engagement process since the 2021 BC Heat Dome, which involved engagement and community consultation to hear and learn from equity-deserving populations on lived experiences from the 2021 BC Heat Dome.
