No man is an island. Human beings are social creatures; they need community, closeness and friendship. Corona in particular has made it clear how these needs have not been met: loneliness is a health factor. In 2024, the German government published a "loneliness barometer" for the first time, which is largely based on research by Maike Luhmann. The psychologist has been researching loneliness for 15 years. The result: poverty, care work, migration and refugee experiences significantly increase the risk. Loneliness affects all age groups, but tends to affect women more than men; people from the East more than people from the West. Janosch Schobin looks at the problem from a global perspective and spoke to people around the world who are affected by loneliness. Salon host Mariel Reichard talks to Luhmann(Einsamkeit) and Schobin(In Zeiten der Einsamkeit) about two books and a universal feeling.
