Both homes and healthcare facilities install night lights to help people move through areas after all other lights have been turned off. New research indicates that it is better if those lights use red bulbs instead of white ones. As Nelson, Bedrosian, Vaughn, Galan, Daye, and Weil found in research with hamsters and night lights, “blue light had the worst effects on mood-related measures, followed closely by white light.
Crompton investigated the design of multifaith spaces in hospitals and airports. He found that “Multifaith has become the default form of religious space in hospitals and airports and has introduced sacred space to places like shops, football grounds and offices where none formerly existed . . .

These findings run counter to traditional views that emotions are communicated exclusively via visual and linguistic channels.” This research confirms the importance of multi-sensory, face-to-face communication.
