Proxemics is the study of measurable distances between people as they interact and how use of space can impact comfort levels. There are different zones of personal space including intimate, personal, social, and public distances. Cultural differences also impact comfort with proximity. Proxemics research examines topics like crowding and how density, interaction levels, control, and other factors influence perceptions of space. Environmental psychology further studies relationships between the physical environment and human behavior, seeking to understand and address issues like noise pollution, density, and feelings of crowding.
