What is good light | Good Light Group

for a healthier and happier life

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!

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.

You might be one of them!

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.

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.

Good light is essential for a properly synchronized biological clock, responsible for our day-night rhythm, and it improves our sleep.

Good light makes us feel energetic, alert, and concentrated during the day.

Good light makes us feel welcome, relaxed, safe, cozy and happy.

Good light supports our vision; it shows us objects, colours, contrasts, and motion.
