<ul><li>A study from the University of Ottawa’s Human and Environmental Physiology Research Unit (HEPRU) has confirmed that the limits for human thermoregulation—our ability to maintain a stable body temperature in extreme heat—are lower than previously thought.</li><li>The research highlights the urgent need to address the impacts of climate change on human health as many regions may soon experience heat and humidity levels that exceed the safe limits for human survival.</li><li>The study utilized thermal-step protocols and found that participants' core temperature increased significantly when exposed to extreme conditions, indicating the inability to regulate body temperature beyond certain limits.</li><li>Understanding these limits can help guide health policies and public safety measures as cities prepare for hotter summers and adapt to increasingly extreme environments brought about by climate change.</li></ul>
