Heat-Related Health Risks Rise Globally, Study Finds

A new international study analysing data from 751 sites across 26 countries projects that the share of suicide deaths attributable to temperature will increase in every region by 2050, with the magnitude depending on emission scenarios and geography. Professor Éric Lavigne of the University of Ottawa warned that climate change could amplify suicide mortality worldwide and stressed the need for adaptive mitigation strategies.

In Tunisia, health officials highlighted the invisible danger of heatstroke, which can occur even in shaded or indoor environments. Dr. Nour Nwira explained that body‑temperature exceeding 40 °C can cause organ failure, brain damage, and rapid progression to coma or death, especially among the elderly, children and people with chronic illnesses. She urged immediate cooling and medical care, and emphasized preventive measures such as staying in ventilated spaces, avoiding closed vehicles, and staying hydrated.
