The aim of the worksite study is to elucidate the strain reducing impact of different forms of spending lunch breaks. With the help of the so-called silent room cabin concept, it was possible to induce a lunch-break relaxation opportunity that provided visual and territorial privacy. To evaluate the proposed effects, 14 call center agents were assigned to either 20 min progressive muscle relaxa...

Background and Objectives:Nurses in intensive care (ICU) wards often experience a wide range of stressful situations. Excessive work stress influences nurses’ physical and mental health and declines their life quality and the ability to work. High psychological stress can cause job dissatisfaction and job strain. The aim of this study was to explore the effects of psychological...

ONE might not immediately associate postage stamps with the promotion of mental health ?although philately as a strain-relieving pastime is not without its therapeutic value?but stamps have long since acquired a wider significance than Sir Rowland Hill could ever have envisaged. They have become established as miniature advertising posters, exemplifying on world-wide correspondence an immense v...
