| Resumen |
An office environment was reconstituted in a lighting laboratory. Volunteers spent a working day (9am-4pm) in the space under one of two illumination levels, reading, working at set tasks or undergoing tests. Pre- and post-"shift" urine samples were collected for cortisol and melatonin determination. High illumination (1700 lux) increased visual discomfort and reduced the subjects' opinion of the environment in comparison with the low level (450 lux), and electroencephalographic changes were observed. The effects were more marked with "daylight" tubes than with "warm white" ones. No effect on hormone excretion was observed. |
