Besides vision, light can impact other processes such as circadian, neuroendocrine, and neurobehavioral responses. It is called non-visual effects of light because they are not directly involved with image formation, and they became an additional dimension in the traditional objectives of architectural lighting, which should provide the proper light for visual performance, for visual comfort, for the aesthetic appreciation of the space and for energy conservation. For instance, in working environments, light must serve not only to meet task demands but also for comfort and health. People respond to environmental exposure through a holistic process composed of psychobiological correlates. To date, the most studied light-reactive hormone is melatonin since light can have an acute suppressive effect on this hormone. As to psychological states, seasonal affective disorder (SAD) probably constitutes the best example of light?s effect on mood and behaviour, and the abnormal pattern of melatonin secretion in SAD sufferers is still the main hypothesis as to the genesis of this disorder. This conference aims to show the possible contributions from the field of lighting research to covid-19 pandemic and to post pandemic economy in terms of: melatonin related health and wellbeing, vitamin D production in response to ultraviolet radiation on the skin, and the concept of sustainable lighting design referred to efficient lighting technologies such as LEDs, as well as guidelines to minimize circadian disruption and to improve productivity.
