Coefficients of biological markers, psychological health indicators, and quality of life across various quantiles of thriving levels. Quantile regression analysis demonstrates the coefficients of biological markers (CAR, melatonin), psychological indicators [anxiety, depression, character strengths (self-control, inquisitiveness, caring)], and quality of life across thriving quantiles (25th, 50th, and 75th percentiles). The results reveal the varying impact of these factors on thriving at different levels. Abbreviation: CAR: Cortisol awakening response
