Accurate detection and monitoring of mental stress can lead to timely interventions and improved mental health outcomes. This study presents a novel approach to mental stress detection by leveraging ensemble machine learning methods. By integrating multiple machine learning algorithms, the proposed ensemble model enhances prediction accuracy and reliability. The effectiveness of the ensemble model is evaluated using physiological and behavioral data collected from participants.

INTRODUCTION:  \nMental stress is a significant factor contributing to various physical and psychological health problems, including cardiovascular diseases, anxiety, and depression. With the increasing demands of modern life, the need for effective mental stress detection mechanisms has become more critical. Traditional methods of stress assessment, such as self-report questionnaires and clinical evaluations, are subjective and often fail to provide real-time insights[1] . Advances in machine learning offer promising solutions for objective and continuous stress monitoring.  \nIn this study, we explore the application of ensemble machine learning methods to detect mental stress. Ensemble methods combine multiple machine learning models to improve prediction accuracy and generalizability. By analyzing physiological signals (e.g., heart rate, skin conductance) and behavioral data (e.g., activity levels, sleep patterns), we aim to develop a robust system capable of identifying stress states with high precision.  \nManaging stress has become crucial for people of all generations, necessitating extensive global attention. According to the 2018 Cigna 360° Well-Being Survey –  \nFuture Assured, 86% of people worldwide experience stress, with this figure rising to 89% in India. Additionally, approximately 75% of the local community lacks the confidence to discuss their pressures with a care provider, citing cost as one of the challenges. Consequently, the study of stress [2]and its management is currently a popular topic among scholars.  \nStress is the body's physical, behavioral, and emotional response to external and internal factors such as illnesses, lack of sleep, exhaustion, emotions, and expectations. Workplace tension, interpersonal disputes, environmental contamination, and poor job health also contribute to stress. Stress often arises when an individual encounters an unusual scenario and struggles to cope with the associated worry and anxiety. When mental and physical resources fail to meet demands, stress occurs.  \nPhysiological indicators of stress include elevated heart rate variability (HRV), respiration rate, galvanic skin response, muscle tension, and others. The autonomic nervous system (ANS), which includes the sympathetic and parasympathetic branches[3], plays a key role in the body's physiological reaction to stress. Chronic stress can disrupt the balance between these branches, with potential impacts on heart function. Electrocardiogram (ECG) signals are widely used to assess stress due to their reliability in capturing heart function changes.  \nHRV, which measures the time interval between successive ECG signal pulses, is a crucial variable ","cbCailAMpaAenkol","https://ap.wps.com/l/cbCailAMpaAenkol","pdf",490924,1,"English","en",105,"# Introduction\n## Mental stress and its impacts\n## Physiological and
