Professor Björn Rasch is a professor in Cognitive Biopsychology and Methods in the Department of Psychology at the University of Fribourg, Switzerland. His research covers how sleep helps us keep memories, and how stress, relaxation and suggestion shape the quality of sleep. He answered our questions in November 2026 on why frightening evenings turn up in dreams, how anticipating stress changes sleep, and what the evidence says about relaxation and slow breathing. His staff page is on the University of Fribourg website.
