Humans have displayed evidence of epigenetic changes such as DNA methylation, differentiation in expression, and histone modification due to environmental exposures. Carcinogen development in humans has been studied in correlation to environmental inducements such as chemical and physical exposures and their transformative abilities on epigenetics.
Epigenetics of anxiety and stress–related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

Multiple epigenetic factors can influence the state of genes and alter the epigenetic state. Due to the multivariate nature of environmental factors, it is difficult for researchers to pinpoint the exact cause of epigenetic changes outside of a laboratory setting. [38]
While the psychological impact of climate change is largely negative, related social engagement can have positive effects on mental wellbeing. The psychological impacts of climate change concerns effects that climate change can have on individuals' mental and emotional well-being. People experience a wide range of emotions as they grapple with ...
This year's U.N. climate summit - COP29 - is being held during yet another record-breaking year of higher global temperatures, adding pressure to negotiations aimed at curbing climate change.
These behavior changes include: engaging with the public about climate change, contributing at a personal, communal, cultural and political level by supporting effective change through activists, scientists, and policy makers, and finally nurturing psychological resilience to the destructive impacts climate change creates now and in the future.
Research in rodents suggests that epigenetic changes can be observed in genes associated with the hypothalamic-pituitary-adrenal (HPA) axis, which coordinates the body's stress response system. [113] [114] [19] Non-heritable stress-related epigenetic changes have also been studied in monkeys. [115]
