Why do people sigh when they are sitting down?
A study by Vlemincx and colleagues at the University of Leuven suggests that, indeed, sighing acts as a physical—and mental—reset. By studying breathing patterns of participants for 20 minutes while sitting quietly, the authors found that during the time preceding a sigh, breathing begins to vary, changing in speed or shallowness.
