Psychological Stress: A key etiological factor in Kushta (Skin Disorders)

Kushta (skin diseases) in Ayurveda is a multifactorial disorder influenced by psychological, physiological, and environmental factors. Classical texts and modern studies highlight the role of psychological stressors and emotional states in the manifestation and progression of skin diseases. Emotions such as Chinta (anxiety), Shoka (grief), Krodha (anger), and Bhaya (fear) are classified as Manasika Bhavas and, when excessive, transform into urges (Vegas), leading to psychological imbalances (Manasika Vikaras). The dominance of Rajas and Tamas over Satva affects mental stability, rendering individuals prone to skin conditions. Shared embryological origins of the skin and nervous system elucidate their interdependence. Psychological stress affects skin function, including sweating (regulated by Vyana Vayu and Bhrajaka Pitta), activation of the HPA (hypothalamic-pituitary-adrenal) axis and sympathetic nervous system leading to conditions like dryness, discoloration, and inflammation seen in psoriasis, urticaria, dermatitis etc. Chronic stress elevates cortisol levels, accelerating aging and predisposing individuals to infections and inflammatory skin disorders.
