Why using color blue?

Doesn't blue light keep your brain active?

It is true that long exposure to high intensity blue light can inhibit the production of melatonin (the sleep hormone), and therefore prevent you from falling asleep.

Having that said, Dodow's light is far too weak to have an impact on melatonin secretion:

  • Dodow light intensity < 1 lux
  • Computer or TV screen = 60 lux

Once projected on the ceiling, Dodow's light is set to its maximum intensity, which for someone lying in bed, has a very low intensity (less than 1 lux).

Compared to the high intensity of a computer or television screen (about 60 lux at a distance of 50cm). 

There’s also the additional low exposure time (8 to 20 minutes).  

The intensity of the light can be adjusted, if you think that the basic mode is too bright!

Why we made this choice

We hesitated for a long time between different colours, especially between blue and orange.

Blue is known to have relaxing properties and influences stress management, in contrast to warm colours which are synonymous with danger, excitement, heat.

After having developed various orange (590 nm, 601 nm…) and blue (465 nm, 470 nm…) prototypes, we were able to confirm, after a series of user tests, that the results were more conclusive with the colour cyan (465 nm). 

Now you know why we decided for the color blue!

This study, conducted in 2020, determines the effect of colors on stress reduction and shows that blue color is the most effective one to reduce stress levels.
