TLDR Stress and emotional factors can worsen skin conditions by affecting the immune system.
The 2005 document examines the impact of psychosocial stressors on dermatological conditions through the lens of psychoneuroimmunology (PNI). It outlines how stress, anxiety, and poor social relationships can lead to immune dysregulation, which in turn can affect skin health. The paper discusses the role of the endocrine system in mediating the effects of psychological factors on immune function, with stress and depression triggering hormonal changes that impact immunity. It also connects psychiatric syndromes with increased proinflammatory cytokines. The document specifically mentions the exacerbation of skin conditions such as hyperhidrosis, telogen effluvium, alopecia areata, vitiligo, psoriasis, and atopic dermatitis due to psychological factors. It highlights the potential of neuropeptides like α-MSH as anti-inflammatory agents in skin conditions and calls for further research to understand the molecular mechanisms and therapeutic benefits of psychological interventions in dermatology. The conclusion emphasizes the significant influence of the brain, immune, and endocrine systems on skin health, particularly in the context of psychosocial stressors.
