This section on Light for Health intends to:

  • Highlight the necessity for lighting research
  • Show that good lighting design needs to incorporate the specific levels of light required for both vision and the biological clock
  • Invites researchers to publish their research studies on light and health
  • Raise awareness of the importance health-centered lighting design can have on the health and wellbeing of people, particularly the elderly, their relatives and care givers

Since Antiquity there have been speculations, assumptions and anecdotes about the healing qualities of light. When Alexander Fleming discovered penicillin in 1928, light was no longer seen as the desired cure for certain diseases. As a result investigations into the effects of light on health dwindled.

Subsequently Lighting Research started to investigate human vision under artificial lighting conditions. The intention was to maximise the ability to see well under artificial light so as to perform tasks with accuracy while being in visually pleasing surroundings.

The discovery of the fourth photoreceptor in 2001 and its link to the biological clock, renewed scientific interest into the benefits of light on health, and current research continues to reveal and clarify specific light related benefits on health.

Furthermore, lighting regulations need to be formulated to include circadian-active lighting guidelines.


Eventually we all will benefit from visual and circadian-active environments.
