Active shooter drills are widely used in schools throughout the United States, with more than 92% of public schools having an active shooter plan. These drills can increase student stress and anxiety and can have a variety of negative effects, such as somatic complaints, anxiety, poor self-regulation of emotions and behaviors, risk for depression, and prevalence of obesity and eating disorders. This article describes the efficacy of physical activity breaks, mindful breathing techniques, and emotional regulation strategies to reduce stress reactivity and enhance recovery in elementary-age students following active shooter safety drills. A list of example activities is provided for each of the three stress management categories. Each of the activities can be adapted to various developmental levels (i.e., K-12), settings (i.e., classroom, hallway, outdoors), and time availability (i.e., one minute to 10 minutes). The strategies may also be utilized following other emergency drills or during other times of high student and classroom stress.
