Theatre is more than entertainment—it is a powerful tool for training, preparedness, and care. This course explores how theatrical techniques are used in real-world, life-saving contexts such as healthcare simulation, disaster response training, emergency preparedness, and community education. Participants will learn how storytelling, character embodiment, environmental design, and applied performance help first responders and medical professionals rehearse complex, high-stakes situations safely and effectively. Drawing from large-scale disaster simulations and interdisciplinary collaborations, the course reveals how theatre artists contribute to realism, empathy, communication, and decision-making under pressure. No prior theatre experience is required.
