The quality of the built environment involves spatial characteristics that affect the perception and the behaviour of its users. Factors such as ventilation, temperature, lighting, shape and volume must be worked out in order to provide appropriate environments that promote a good quality of life. Because environmental perception is derived from the processing of sensory stimulus, the premise of this doctorate thesis is that the biological rhythm and the psychological state of users are directly influenced by spatial variables. Thus, the hypothesis of the research is that the hospital environment, controlled exclusively by artificial lighting and climate control, and associated to the intense pace of work, alter the biological rhythm of resident physicians increasing the occurrence of psychological diseases and increasing the chances of them making diagnostic errors. The goal is to identify how the hospital environment under artificial conditions, especially lighting and temperature, affect the quality of life and the perception of medical residents through the analysis of physiological and psychological variables. Therefore, the evaluated environmental variables were; i. quantitative gauging of the temperature, lighting, relative humidity, air velocity and physical aspects; ii. qualitative questionnaires regarding visual perception, thermal, acoustic and use of space. Psycho-physiological aspects of resident physicians were evaluated according to; i. emotional variables with validated instruments in Brazil for the demarcation of anxiety, depression, stress and psychiatric disorder in the workplace, in addition to sleep and its quality; ii. hormonal variables by saliva collection and the use of ELISA test for cortisol and melatonin dosage. The research is characterized as exploratory and prospective due to the observed outcome variables and follows the design of experimental research. The study was conducted in real conditions in the Radiology Department of the Hospital at UNICAMP/Campinas. Among the results found with resident doctors were different psycho-physiological responses according to the environmental conditions; also that these same conditions did not reach values able to fully interfere in the psycho-physiological health of physicians whatever the year of residency. This research contributes to the advance of the state of the art, adding information to the data already collected on the influence of artificial environmental conditions on the perception and psycho-physiological health of a proportion of the hospital population, contributing to the development of the quality of the environment through architectural design.
