22. A sleep-inducing device for inducing sleep in a user, the device comprising:
a light source for emitting a substantially monochromatic or almost monochromatic red light at a wavelength of 625 nm±15 nm, favoring the falling asleep of the user;
a control unit configured to automatically control said light source in accordance with a predefined law according to which a light power emitted by said light source progressively decreases over time, evolving automatically between a maximum power value and a minimum power value, the light power emitted by said light source at one moment being always higher than or equal to the light power emitted at a later moment, for the whole duration of use of the sleep-inducing device, said light power never increasing after having reached said maximum power value, wherein the maximum power value is between 600 lux and 885 lux;
a box, wherein said light source is arranged in said box, said box being provided with a basement that allows the box to stably rest on a planar surface, with the light source directing the red light upwards and away from the user, said predefined law being configured for said light source to reach said minimum power value from said maximum power value after a predetermined power-off duration has elapsed;
a timer configured to automatically count said predetermined power-off duration from a power-on of said device; and
a power-off means for automatically powering off said device at an end of said predetermined power off duration.
