چکیده :

This study presents an integrated framework for predicting nurses’ stress by combining physiological data from wearable sensors with hospital architectural and environmental features. Over 11 million samples from 15 nurses during real hospital shifts were analyzed, including electrodermal activity, heart rate, and body temperature, using machine learning models such as Random Forest, XGBoost, LightGBM, CatBoost, and a Voting Ensemble. Shorter time windows (30 seconds) and class-weight adjustment improved prediction accuracy, with the Voting Ensemble achieving 82% accuracy and an F1-score of 0.80. Simulated mapping of stress levels onto hospital environments demonstrated that natural light, short circulation paths, greenery, and quiet rest areas significantly reduce physiological stress. This multidimensional approach provides actionable insights for evidence-based hospital design, promoting staff well-being, reducing fatigue, and enhancing operational efficiency.
