Good light

for a healthier and happier life

Good light

Good light is the right light at the right time. We need bright light during the day and dim light in the evening. So we can function at our best!

How does it work?

Light-sensitive cells in your eyes, or as we call them 'daylight detectors', connect to the part of the brain that houses your biological clock.

This clock regulates daily bodily rhythms such as sleep, energy levels, mood, and the digestive system.

These detectors require daylight to estimate the time of day and help coordinate the appropriate bodily processes at the right times.

Year 1800

People spent most of their daytime outdoors in natural daylight.


We are spending 90% of our time outdoors, far away from the natural daylight our bodies need.

What can you do?

Be outside a lot during the day, especially in the morning.

Stay within one meter of
a window. After every 
20 minutes of screentime get up and look at the sky for 20 seconds.

Install electric good light
that mimics daylight
from sunrise to sunset,
ensuring you receive 
at least 500 lux in your eyes during the daytime.

Aim to keep lighting below 10 lux three hours before bedtime by avoiding bright lights and setting your screen to night mode.
