A study conducted by the University of Hong Kong has found that anxiety experienced at the start of the workweek, commonly referred to as "Monday anxiety," triggers a prolonged spike in stress hormone levels. This effect is measurable and can have lasting impacts on health, persisting for months. The research indicates that the tension associated with beginning the week affects not only working adults but also older adults who are no longer employed. The study highlights the physiological toll that the psychological stress of Monday can impose, emphasizing the role of cortisol, the stress hormone, in this process.
