Biocentric lighting

Biocentric lighting (BCL) by BrainLit simulates the important aspects of daylight, including wavelength, intensity, direction, timing, and duration, to sustain a healthy circadian rhythm.

Biocentric lighting environments by BrainLit directly counter the effects of circadian misalignment caused by lack of proper light exposure. As an intelligent lighting solution that accurately simulates natural daylight for human well-being, Biocentric lighting uses algorithm-based light recipes to both balance and sustain the circadian rhythm. Benefits of a synchronized circadian rhythm as supported by Biocentric lighting include:

  • Better sleep¹
  • Increased alertness²
  • Improved cognitive performance³

Yes! But you would need to be spending a few hours in the early day outdoors, as this helps support a healthy circadian rhythm. 


Circadian rhythms helps regulate many bodily functions such as sleep, metabolism and cognition. Light is the most important time cue for the circadian rhythm.

When we spend most of our time indoors, our circadian rhythms may struggle to synchronize without exposure to daylight. 

Most of us don’t get enough light to synchronize with the solar day. We also sleep too little. This can lead to circadian disruption, which associated with short and long term health effects. 

The disruption of our circadian rhythm can happen over different periods and occasions during our life. Factors which can impact our circadian rhythm are lack of daylight exposure and frequent changes in our sleep schedule.

A synchronized circadian rhythm is a vital piece of the puzzle that helps your body’s internal mechanisms function properly. It affects your sleep patterns, as well as other aspects of your body’s functioning, such as hormones, body temperature, and eating habits.

Biocentric lighting is a system that can handle circadian adaptation by synchronizing our biological rhythm with solar time.

Light has an effect on our biology and wellbeing that is greater than most people are aware of and that goes beyond the visual effects of light. Light affects normal human physiology in a profound way such as sleep and growth.

People differ in their preferred timing of sleep and wake, which is a physiological behaviour known as chronotypes
