Ergonomics is the field of study that deals with the design of safe and healthy workstations. Ergonomics studies seek to define the biological, psychological and social prerequisites for human work. It is the aim of ergonomics to adjust work equipment to individuals with due regard for their capacity to perform and bear stress as well as to create amenable conditions at the workplace (i.e. lighting, natural light, air-conditioning, ventilation, etc.) by avoiding overload.
