Anger, resentment and stress are part of everyday life - both at work and at home. But when emotions boil over, it's not just our pulse that rises: our words also become faster, sharper and ill-considered. This puts a strain on relationships, costs energy and even affects our heart health in the long term. In this digital lecture, you will learn how to recognise, regulate and consciously control inner tension at an early stage. You will learn how breathing, body language and inner attitude interact - and what you can do specifically to react more calmly, clearly and healthily in difficult moments. Because staying emotionally calm not only protects your heart, but also your interpersonal relationships.
