Health risks – A coup for the Senior Climate Women On April 9, 2024, the "Senior Climate Women" association achieved a victory before the European Court of Human Rights. The Strasbourg judges addressed the complaint that Switzerland is not doing enough to combat climate change. The verdict: Switzerland's inadequate climate protection violates the human rights of the elderly plaintiffs. Heat Adaptation – Using Warmth to Combat the Heat Heat researcher Kay Hanusch from Bern University of Applied Sciences is convinced: "In the long term, we need to rethink our approach." Instead of cooling down during a heat wave, it would make more sense to acclimate to higher temperatures with moderate heat training in the spring. Those who expose themselves to the heat are better able to tolerate it.

Her areas of expertise are mental health and the use of medication, both of which pose underestimated risks. «Puls» Chat – Questions and Answers on the Topic of “Living with the Heat” Are you suffering from the heat and want to know what you can do about it?
