Research on the effectiveness of mindfulness interventions has grown substantially in the past 15 years, and has spread from clinical/medical interventions to more population-based application such as at the school level. For students, training in mindfulness practice has demonstrated improvements in working memory, attention, academic skills, social skills, emotional regulation, and self-esteem, as well as self-reported improvements in mood and decreases in anxiety, stress, and fatigue. This approach can be used at the start or end of class, or between activities; it can happen during a transition time, as a way to help students calm and prepare for a reflective activity after physical activity.
