The use of mindfulness-based practices has two main applications in military populations. The first is to help those in need of rehabilitation from physical and psychological trauma and the second is to improve stress resilience (adaptive capacity) in anticipation of high stress situations. Military personnel face exceptionally high-stress situations during both selection and pre-deployment training. Their ability to remain focused, exercise effective decision-making and adapt is tested under intense physical and psychological conditions.
The US Military have invested substantially into researching and delivering resilience training within their various divisions. A number of approaches have been studied including Mindfulness-Based Interventions (MBIs) to improve internal awareness of nervous system regulation, emotional regulation and decision-making. This may be of particular relevance to UK military/first responder organisations facing extreme/prolonged exposure to stress and elite sportsmen/women.
