Background: Sleep significantly affects physical and mental health, and influences factors such as posture, muscle strength, and psychological well-being. Despite its importance, modern lifestyle factors contribute to widespread sleep disturbances, highlighting the necessity for deeper insight into how sleep interacts with health indicators. Purpose: This study aimed to investigate the complex relationships among sleep duration and quality, physical health indicators, and mental health status in healthy adults. Study design: Cross-sectional study Methods: A total of 66 healthy adults aged between 20 and 60 years were assessed for sleep quality, depressive symptoms, sleep duration, spinal curvature, and thoracic muscle strength. Pearson’s correlation coefficient was used to analyze the relationships among these variables. Results: Sleep duration was negatively correlated with the PSQI score (r = –0.344, p = 0.005) and kyphosis angle (r = –0.407, p = 0.001). Poor sleep quality positively correlated with depressive symptoms (r = 0.311, p = 0.011). The kyphosis angle was positively correlated with the thoracic extensor muscle strength (r = 0.675, p < 0.001). Conclusions: This study demonstrates significant associations among sleep quality, spinal alignment, and mental health. This emphasizes the need for integrated clinical approaches that address sleep, posture, and psychological well-being to enhance overall health outcomes.
