Astrology and Personality: A Scientific Framework for Zodiac Typology, Chronobiology, and Biophysical Resonance

Background/Objectives: This review explores whether astrological character typologies—rooted in symbolic archetypes—correlate with measurable patterns in personality psychology, psychiatric epidemiology, and developmental chronobiology. Methods: Drawing on over 100 peer-reviewed studies across psychology, psychiatry, neuroendocrinology, and chronobiology, we examined data on birth-month effects, seasonal neurodevelopment, personality inventories (e.g., Big Five), and psychiatric incidence. These were systematically cross-compared with astrological archetypes to evaluate symbolic alignment with biological traits. Results: Statistically significant associations were observed between season-of-birth and neuropsychiatric outcomes—for example, higher schizophrenia rates in winter births and increased ADHD diagnoses in spring—echoing traditional astrological depictions of psychological imbalance and stimulation. Fire-sign analogues (e.g., Aries, Leo, Sagittarius) showed correlations with extraversion and novelty-seeking, while water-sign types aligned with emotional sensitivity and affective vulnerability. Perinatal light exposure and circadian hormone cycles (e.g. melatonin, dopamine) appear to mediate these patterns. Conclusions: Astrological archetypes may symbolically reflect underlying biopsychological rhythms—capturing trends in temperament, personality structure, and psychiatric risk shaped by seasonal and chronobiological factors.
