In an open letter, hundreds of health workers in Switzerland are calling for intensified efforts against climate change, citing significant health risks. They highlight that increasing heatwaves contribute to higher mortality among the elderly and complications for unborn babies. Notably, studies indicate that heat stress can raise the risk of premature births by 20%. Allergies and mental health issues are also on the rise, with one-fifth of the Swiss population suffering from hay fever, potentially linked to climate change. The Swiss government claims to be taking steps to address these challenges, including reducing greenhouse gas emissions.
