Blue Monday!

Updated: Jan 21

Some say the most depressing day of the year, but why?

The third Monday of the year, the New Year's resolutions turn out to be more difficult to keep than expected. It’s cold and dark, and the last months we’ve been mostly indoors. We’ve developed a winter blues and depressed feelings. In this time of the year, we definitely need light indoors that mimics daylight.

The best way to avoid a winter depression is by getting enough good light during the day. It’s very healthy to go outside and enjoy the daylight for a couple of hours. But for most people this is not possible..


We developed the 20-20-2 rule, which helps you bringing enough Good Light in your life. Because light is such an essential part of feeling happier, healthier and more energetic.

This is what you need to do:



  • If you are inside, measure the light that’s entering your eye with a lux meter app on your phone (the light should be at least 1000 lux during daytime).

  • Make sure you have Good Light while working. Locate your desk within one meter from a window or increase the electric light level to 1000 lux entering your eyes.

  • Live by the 20-20-2 rule. After every 20 minutes of screen time, look at the sky for 20 seconds. Spend at least 2 hours outside every day, preferably in the morning.
