Long-term stress is a major and still rising public health problem, which is associated with increased risk of disease and mortality. In this review, we find that a systematic literature search of stress-reducing interventions tested in a randomised controlled trial (RCT)-design in Denmark showed, that interventions are only tested one or two times and only by the same research group. Furthermore, the international literature is not reviewed sufficiently before developing new interventions. Mindfulness-based stress reduction is a well-tested stress-reducing intervention, which is tested in more than 100 RCTs. In Great Britain, Mindfulness All-Party Parliamentary Group has used this information to make recommendations to Parliament.
