Stress, a state of mental tension triggered by challenging circumstances, has become a global risk factor impacting individual well-being. Understanding variations in stress resilience is crucial for tailoring treatment strategies. Previous studies have explored stress prediction using measures like electroencephalography (EEG), blood pressure (BP), heart rate (HR), and interventions such as Kriya Yoga and mindfulness meditation. The experimentation is done on the data collected from people who practice heartfulness meditation regularly. The research employs machine learning (ML) algorithms alongside physiological parameters such as EEG, BP, HR, and psychological parameters, perceived stress scale (PSS), to precisely classify, measure, and predict stress levels. The investigations are done using K-nearest neighbor (KNN), random forest (RF), and kernel-support vector machine (k-SVM) . An accuracy of 98.27% accuracy was achieved with the RF algorithm in classifying stressed and non-stressed individuals.\u003Cbr>This is an open access article under the CC BY-SA license.\u003Cbr> |\n| Harish H.

INTRODUCTION  \nIn recent days, human beings have suffered from stress for many reasons such as financial stability, and work pressure, family responsibility. The growing prevalence of mental health disorders and the need for advanced technologies to assist in early detection and management. Mental health issues related to stress disorders have become a significant global concern affecting millions of individuals worldwide. As depicted in Figure 1, 34% of people across the world feel that they are stressed, and 31% of people feel stressed as they cannot deal with things [1] . Like the global scenario, in India also the fast-paced modern lifestyle, high work demands, academic pressures, and competitive environments often contribute to elevated stress levels among individuals. Additionally, factors such as socioeconomic challenges, urbanization, and digitalization have added complexity to the stress landscape in India. Stress is characterized as a condition of anxiety or mental tension brought on by a challenging circumstance. Stress is a normal human reaction that motivates us to deal with problems and dangers in our lives. Everyone goes through periods of stress [2] . As a complex relationship of physiological, cognitive, and emotional responses to external pressures, stress poses significant challenges to both individual well-being and public health systems [3] . Predicting stress levels in individuals is crucial for early intervention and prevention of stress-related health issues like anxiety, depression, and cardiovascular diseases. Identifying stress using various parameters involves assessing  \nphysiological, behavioral, and psychological indicators.
