Mental health plays a vital role in how individuals function, connect with others, and respond to daily challenges. This report outlines what mental health is, examines the biological, psychological, and social factors that influence it, and highlights the growing impact of environmental stressors like air pollution and climate change. It also discusses how mental health is connected to our community, especially during times of environmental or social stress. Using the Salton Sea region as a lens, we explore how environmental conditions can shape mental well-being and discuss practical ways to support mental health on both individual and community levels.
