Stress, a response to perceived pressure, can lead to mental health issues when chronic. Heart rate variability (HRV), measuring the time between heartbeats, is used to assess stress physiologically. Despite its use, accurately detecting stress via HRV remains challenging. Our study investigates HRV's potential as a stress biomarker, employing a convolutional neural network (CNN) to classify stress into no stress, interruption stress, and time pressure stress categories. Utilizing the Stress Classification - WIN23 dataset, our model achieves a remarkable 95% accuracy, with superior precision, recall, F1-score, and Matthews correlation coefficient (MCC) compared to existing methods. Feature extraction techniques like analysis of variance (ANOVA) highlight essential HRV features for stress detection, enhancing model accuracy and robustness. This underscores HRV-based stress detection's potential, emphasizing machine learning's crucial role in precise stress level classification.
