Good light
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 your body can function at it's best!
Sleep better. Feel more energetic. Improve your mood with good light.
Did you know most people live and work with insufficient light?
Sleeping poorly? Low in energy? Difficulty concentrating? Feeling down?
You might be one of them!
Indoor light is too weak during the day and often too bright in the evening. This disrupts your body clock and negatively affects
your sleep, health, and mood.
200 years later
Year 1800
People spent most of their daytime outdoors in natural daylight.
Today
We are spending 90% of our time outdoors, far away from the natural daylight our bodies need.
Our biological clock needs rhythm: lots of light during the day, and very little in the evening. The right light at the right time is essential.
How does light send signals
to your brain?
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.
What can you do?
1
Get at least 500 lux of daylight or electric light first thing in the morning to signal your body that the day has started.
Spend plenty of time outside during the day, especially in the morning.
2
3
Stay within one meter of a window.
5
Keep light levels below
10 lux three hours before bedtime by avoiding bright lights and setting your screen to night mode.
6
Keep light levels below
1 lux at night, even when
getting out of bed, and
avoid screens whenever
possible.
