Police officers, firefighters, paramedics, and other emergency professionals operate in high-pressure, unpredictable environments where stress is constant and cumulative. Chronic exposure to stress impacts decision-making, situational awareness, physical health, and long-term mental wellbeing. While consumer wearables (e.g., Garmin, Apple Watch, Whoop) can estimate stress using heart rate variability (HRV), skin conductance, or movement, current solutions focus on individual wellness rather than operational environments and provide retrospective insights rather than actionable real-time intelligence. Emergency organizations need a new generation of wearable-enabled systems that move from passive stress tracking to operational stress intelligence. How might we design wearable technologies and data intelligence systems that: Measure stress reliably in extreme, real-world conditions Create a dynamic overview of individual and team stress states Transform stress data into actionable operational insights Support both performance and long-term wellbeing In this project we are aiming to create demonstrations of wearable stress detection tech for professionals in emergency field and concepts to utilize the data in operational, real-time situations to benefit the professionals.
