Environmental psychology is a branch of psychology that focuses on understanding the relationship between individuals and their physical surroundings. This field explores how the built environment, natural environment, and other aspects of the physical world impact human behavior, emotions, and well-being. Researchers in environmental psychology study topics such as the effects of urban design on stress levels, the influence of natural environments on mental health, and the psychological impacts of climate change and environmental degradation. By investigating these relationships, environmental psychologists aim to promote positive environmental behavior and design spaces that enhance human well-being and quality of life.
