ABSTRACT: OBJECTIVE: To discuss the relationships between sleep, circadian rhythms, and mental health, considering the neurophysiological mechanisms involved in the regulation of the sleep-wake cycle, their effects on cognitive and emotional functioning, and their implications for professional training and practice in Psychology. MATERIALS AND METHODS: This is a theoretical and reflective study based on a narrative review of scientific literature on sleep, chronobiology, neurophysiology, and mental health. The discussion is grounded in scientific publications addressing homeostatic and circadian mechanisms, neural circuits involved in sleep-wake regulation, memory consolidation and emotional regulation processes, as well as the relationships between sleep disturbances and mental disorders. RESULTS AND DISCUSSION: The literature analyzed demonstrates that sleep is an active biological process essential for maintaining homeostasis, memory consolidation, learning, and emotional regulation. A bidirectional relationship is observed between sleep disturbances and psychological distress, in which persistent sleep difficulties may increase emotional vulnerability, while symptoms of anxiety, depression, and stress may compromise sleep quality and continuity. The effects of artificial light exposure, hyperconnectivity, work schedules, and social conditions on the organization of biological rhythms are also highlighted. FINAL CONSIDERATIONS: Understanding sleep as a constitutive dimension of mental health broadens the possibilities for psychological assessment and intervention, fostering an integrated approach to the biological, emotional, behavioral, and social aspects of individuals. The importance of recognizing persistent sleep disturbances, respecting professional boundaries, and considering environmental and social conditions that influence sleep health is emphasized.
