Abstract Light not only has an optical function, but also an energetic one, which stimulates and regulates organ function and metabolism. Artificial light differs from daylight in its spectral composition, its monotonous character, its incidence and its intensity. Over-intense artificial light activates hormone secretion, giving rise to a stress reaction. Combination of light sources with different spectra in a lighting unit, and addition of local lighting, yield satisfactory results. The results of tests to determine the influence of daylight and artificial light on ACTH and hydrocortisone production in man are given.
