Circadian Stimulus

Light is the primary regulator of circadian functions in humans. Circadian light differs from the generally conceived definition of visual light, in that it refers to the effect of lighting on the human circadian system as opposed to light as a stimulus for the human visual system.

The definition of circadian light has the potential to suppress melatonin. The impact of light on a person will vary depending on their physiological state [5]. All individual’s body clocks are set differently from one another.

Problem: Due to recent technical developments, there has been considerable interest in circadian stimulus provided by lighting. However, light that provides circadian stimuli at the wrong time can have a negative effect on one’s health.

Possible Solutions:

• Develop a lighting system that emits light levels corresponding to the physiological state that the user       inputs
• Know the best time of day for you to be exposed to blue light
• Establish lighting systems in healthcare facilities that can calm and energize, as required
• Provide a lighting system that can dynamically change light being delivered between circadian effective to non-circadian effective
• Provide wall or ceiling panels that change color temperature corresponding with information it receives about the user’s sleep schedule, activity patterns, and information about the lights they were exposed to throughout the day
