Raising Awareness About Dangers of Extreme Indoor Temperatures

Recent research conducted by the University of Waterloo highlights the importance of monitoring indoor temperatures to prevent heat-related health risks, especially during heat waves. Using advanced machine-learning algorithms and smart thermostats with Wi-Fi connectivity, the study collected data on indoor temperatures across North America from 2015 to 2024. This innovative approach allows for precise identification of households at risk of life-threatening conditions due to extreme heat inside the home.

Despite existing legislation in Canada that mandates heating standards for public buildings and rental units during cold weather, there are no regulations governing cooling requirements during heatwaves. This gap can leave vulnerable populations exposed to severe health dangers.

The study, titled "Deep Learning Models for Health-Driven Forecasting of Indoor Temperatures in Heat Waves in Canada," demonstrates how AI-based forecasting can predict indoor temperature spikes during heat events. During the 2021 heat storm in British Columbia, nearly all of the 619 heat-related deaths occurred indoors, underscoring the critical need for early detection and intervention.

Heat exposure indoors poses significant risks for elderly individuals, people with pre-existing health conditions, disabilities, and pregnant women. To combat this, researchers are developing online dashboards and early-warning systems that map neighborhood hotspots, enabling authorities to prioritize resources and emergency responses effectively.

Dr. Plinio Morita, a leading researcher at UbiLab, emphasizes that accurately forecasting indoor heat levels is vital for prevention. Temperatures exceeding 26°C for eight or more hours are considered an initial health threat, while sustained temperatures above 31°C drastically increase health risks.

Considering that not all households can afford smart thermostats, Morita advocates for public health programs and government subsidies to promote their adoption. These tools can help prioritize support to the most vulnerable, particularly in low-income communities and long-term care facilities lacking air conditioning.

Once high-risk households are identified, immediate measures such as distributing fans and deploying emergency medical services can be implemented. In the long run, subsidizing smart thermostats and investing in green infrastructure are key strategies to reduce heat risks.

Use of AI and social media offers promising opportunities to enhance public awareness and address misinformation related to climate and health. Overall, early detection and proactive measures are essential to safeguard vulnerable populations from the dangers of extreme indoor heat during heatwaves.
