The research area of home environment focuses on studying the impact of the physical and social aspects of people's living spaces on their health, well-being, and behavior. This can include factors such as air quality, noise levels, access to natural light, layout and design of the home, and interactions with family members or roommates. Researchers in this area may investigate how different home environments affect individuals' mental health, physical health, sleep patterns, stress levels, and overall quality of life. Studies in this field may also examine how interventions or changes to the home environment can lead to positive outcomes for residents.
