“This device is a gift I have made and offert several times since 2 years. The version I made for this tutorial is the most complete of all because it takes into account the suggestions I’ve had in the past. I would also point out that English is not my fluent language but i hope to be understandable.
There are devices that helps you to wake up or fall asleep “naturally” with light. The device I present helps you fall asleep by synchronizing your breathing with the variations of light intensity emitted by it. Inspire by this https://www.mydodow.com/en but with more control and option on it.
With it, you will be able to relax more easily and put aside your thoughts that prevent you from sleeping. Depending on who the device works on and who has tested this principle, you may fall asleep easily in 5 to 15 minutes if it works on you.
The device emits a light whose intensity varies several times per minute. When the intensity of light increases, breathe in, when the intensity decreases, breathe out. During the full cycle, the frequency slowly decreases from 11 to 6 breaths per minute.”
