Associations of Sleep Quality and Perceived Stress with Skin, Scalp, and Hair Health Among 1,017 Chinese Women: A Cross-Sectional Observational Study

This study involving 1,017 Chinese women aged 18-40 found that poor sleep quality and elevated perceived stress are linked to various dermatological issues, including sensitive scalp, skin fatigue, and hair concerns. Poor sleep was associated with sensitive scalp, skin fatigue, skin yellowness, and increased dark eye circles, while elevated stress was linked to hair loss and itchy scalp. The study supports the skin-brain axis hypothesis, suggesting that sleep and stress assessments are important in dermatological research. However, longitudinal studies are needed to establish causality and further explore the mechanisms behind these associations.
