Seborrheic dermatitis (SD) is more common in patients with depression, potentially due to indoor living. SD prevalence correlates with gloomy days, suggesting melatonin may influence summer symptom improvement.

Area of Science:

  • Dermatology
  • Psychiatry
  • Environmental Health

Background:

  • Increased prevalence of seborrheic dermatitis (SD) observed in patients with mood depression.
  • Potential link between indoor living habits of depressed patients and SD.
  • Correlation between SD prevalence and regional gloomy days noted.

Purpose of the Study:

  • To investigate the relationship between gloomy weather and seborrheic dermatitis prevalence.
  • To explore potential environmental and biological factors influencing SD seasonality.
  • To consider melatonin's role in the seasonal improvement of SD.

Main Methods:

  • Epidemiological analysis correlating SD prevalence with meteorological data (gloomy days).
  • Review of existing literature on SD, mood disorders, and environmental factors.

  • Hypothesis generation regarding melatonin's influence on SD.

    • Main Results:

    • SD prevalence in outpatients is directly proportional to the number of gloomy days in their area.
    • Suggests environmental factors beyond UV light impact SD.
    • Highlights a potential role for melatonin in seasonal SD fluctuations.

    Conclusions:

    • Gloomy weather is a significant factor in seborrheic dermatitis prevalence.
    • Melatonin is proposed as a potential mediator for the well-documented summer improvement of SD.
    • Further research into the neuroendocrine regulation of SD is warranted.
