During sleep

Quality of sleep is at its best and shifts between different stages in 90-minute intervals – moving from deep sleep into lighter dream sleep (REM sleep) and then returning to deep sleep.

The hour of the wolf

Way too early to wake up

The body temperature is at its lowest and sleep is at the deepest stage. At this point, the circadian system reverses and cortisol levels increase. Blue light should be avoided to stop any disruption with our inner clock.

Let's get started

Ready for a new day

The sun has a more intense, blue light that makes it easier for us to face the morning. This light actively halts the production of melatonin, and increases the hormone cortisol. The body is waking up.


Mentally prepared

The body fully awake and attentive because of high cortisol levels. This is a good time to engage in mentally demanding activities.


The sun in its zenith

Light levels are at the maximum intensity, and the sun reaches its peak position (except during summer time). After this time, sunlight saturation decreases which causes cortisol levels to dip. Experiencing some extra rays of light after lunch can bring the body back up to speed.


Feeling a bit drowsy?

The intensity of the sun starts to fade, despite it still being noticeably light outdoors. We might experience attention deficits  Bringing daylight indoors will help the body to combat afternoon fatigue in a healthier way.


Dusk draws in

Time to decrease our exposure to blue light to prepare for a good night’s sleep. Most computers, handsets, and tablets reduce lighting automatically.

Nine o'clock in the evening

Soon time to go to bed

After a long day of exposure to daylight, the body has produced melatonin without interruption. As evening approaches, cortisol levels drop, and melatonin prepares the body for a good night’s sleep.


Sunrise and sunset. Indoors.

In BrainLit’s light environments with BioCentric Lighting™, indoor light mimics the natural light that we would be exposed to when outdoors on an optimal day. Daylight controls our natural circadian rhythm, which is crucial for our well-being. Lighting systems in rooms, workplaces, schools, and hospitals are rarely adapted to our natural rhythm. BioCentric Lighting™ helps increase energy levels and make you feel more alert. BrainLit’s light environments provide the right light at the right time which results in better work efficiency and sounder regulation of sleep.

The 2017 Nobel Prize on circadian rhythm

The 2017 Nobel Prize in Physiology or Medicine was awarded to Jeffrey C.Hall, Michael Rosbash, and Michael W. Young for the discovery of the molecular mechanisms that control the circadian rhythm. Their discoveries explain how plants, animals, and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions.

Light environment system

Our lighting system with BioCentric Lighting™ is based on a globally unique software patent that creates healthy light environments for people.

Variations in daylight affect our diurnal rhythm and are needed in order for the body to function properly.
