Season 7 | Episode 17
In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. Faisal Ali, professor of dermatology at the University of Central Lancashire and consultant dermatologist specializing in Mohs micrographic and laser surgery, to explore the fascinating connections between sleep and skin health.
Drawing from recent research published in Clinical and Experimental Dermatology, Dr. Ali explains how sleep serves as a critical regulator of skin physiology, affecting everything from skin surface pH and transepidermal water loss to blood flow and temperature regulation. The conversation delves into the complex interplay of circadian rhythms, hormones, and inflammatory cytokines that govern both sleep patterns and skin homeostasis.
The discussion covers how sleep deprivation accelerates skin aging as an extrinsic factor alongside sun exposure and pollution, with compelling evidence from studies showing that good sleepers have significantly better skin aging scores and improved recovery from UV exposure. Dr. Ali explores the bidirectional nature of this relationship—while poor sleep worsens skin conditions, dermatological disorders like atopic dermatitis, psoriasis, and rosacea can severely disrupt sleep through mechanisms including the itch-scratch cycle and inflammatory processes.
The episode addresses practical clinical concerns including the higher prevalence of sleep disorders in patients with conditions like hidradenitis suppurativa and rosacea, the role of obstructive sleep apnea in various skin conditions, and evidence-based approaches to breaking the itch-scratch cycle that disrupts sleep in dermatological patients.
The conversation also tackles common sleep treatment-related skin issues, from CPAP mask irritation and “maskne” to headgear-induced hair loss, providing practical guidance for managing these complications. Dr. Ali discusses proper skincare routines for CPAP users, including the safety of retinol use under masks and strategies for preventing pressure-related skin breakdown.
Whether you’re a sleep medicine practitioner encountering dermatological complaints, a dermatologist treating patients with sleep disruption, or
simply interested in optimizing both sleep and skin health, this episode provides evidence-based insights into this often-overlooked connection.
Join us for this comprehensive discussion that bridges dermatology and sleep medicine to enhance patient care and understanding.
