We look forward to welcoming you to the 24th National Health Promotion Conference and the 10th Network Conference on Mental Health Switzerland «Mentally healthy and ill – how does that work? Strengthening of resources and prevention in focus». The event will take place on March 2023 in the Kursaal in Bern. It is carried out by Health Promotion Switzerland and the Conference of Cantonal Health Directors in cooperation with the Swiss Mental Health Network. Mental health, a pervasive issue during the Covid-19 pandemic, remains a key concern for health promotion. The conference will discuss how and where we position ourselves in the course of life within the two axes of “health” and “illness” of the psyche. In doing so, we will focus on the many ways to strengthen the resources that underpin mental health. We will also learn how mental health promotion and the prevention of mental illness complement each other synergistically.
