Body clocks, sleep problems, and skin health

Sleep disturbances and light exposure are linked to alterations in skin physiology.

• The skin exhibits circadian rhythms in barrier function, immune activity, and repair processes.
• Sleep loss may impair skin barrier integrity and alter immune function, potentially contributing to inflammatory skin conditions.
• Light exposure is a key factor in regulating biological rhythms, with disruptions potentially affecting skin aging and repair.
• Circadian desynchronization from factors like shift work may impact melatonin secretion and skin health.
• There is a need for further research to clarify how circadian disruption affects skin homeostasis and disease development.
