The Power of Lighting to Well-Being

Abstract

In the theatrical performance world, the lighting designer controls and supports the mood of the performance moment by moment using a composition of intensity, colors and angles of light provided by specialized lighting equipment. However, outside of the theater in the real world, the lighting choices are taken for granted from the day a building’s construction is complete to the day of its renovation. As a result, older buildings have outdated lighting equipment that does not support contemporary human needs. Previous research has proved that lighting intensity, color temperature and wavelength have the connection with human melatonin concentration, secretion and suppression in nocturnal circadian rhythm. This article aims to demonstrate how lighting intensity, color temperature and wavelength affect melatonin concentration which is connected human well-being. The importance of lighting design in our daily lives and well-being should no longer be dismissed.
