Recent studies suggest that environmental exposures, such as maternal stress during pregnancy, tobacco smoke, climate, pollutants, and dietary habits, may play a significant role in the development and progression of atopic dermatitis (AD). Maternal stress and prenatal antibiotic use have been linked to an increased risk of AD in children, while certain dietary factors, such as the consumption of fish, may have protective effects. Exposure to skin irritants, synthetic fabrics, and hard water can exacerbate AD symptoms. Proper skincare, such as daily moisturization and the use of fragrance-free products, is crucial, and bathing practices and UV radiation exposure can also influence disease severity.

Climate factors, such as temperature and humidity, and urban living have also been associated with AD prevalence. Additionally, air pollutants and tobacco smoke may worsen AD symptoms. While breastfeeding and probiotic use have shown potential in reducing the risk of AD, further research is needed to understand their effectiveness. Early interventions, such as proactive moisturizing of high-risk infants, have shown promise in preventing AD or reducing its severity. Research continues to explore how environmental factors and early life exposures can be modulated to manage and prevent AD more effectively.
