Helight™ Sleep - The most advanced sleep aid device on the market!

Helight™ Sleep is completely natural and uses a biomechanism that is triggered passively without your effort.

Turn on	Relax	Sleep
Helight Sleep emits pure red light at a wavelength of 630 nanometers for 14 minutes, then gradually fades out.	Close your eyes. This wavelength passes through your eyelids and is picked up by photosensitive cells, triggering a biomechanism that helps you relax and promotes natural melatonin production.	This signals your body to rest and promotes a deeper, more restful sleep. The device will turn off completely after 28 minutes.

Counteract blue light! Pure red light helps you relax, fall asleep faster and promotes deeper, more restful sleep.

Inspired by NASA

When an astronaut's eyes are exposed to blue light, his or her body suppresses melatonin, a sleep-inducing hormone.[...] In simple terms, the color red reverses the process. Melatonin increases, making the astronaut sleepy, while melanopsin is suppressed.

Further evidence on the negative effects of exposure to the blue component in LED ambient lighting and screens of electronic devices at night disrupting our sleep cycle can be found in various publications, e.g.:

A patented technology developed in Canada

The device was designed in Laval, Quebec by a team of half a dozen engineers.

The result of 3 years of research and development

It is the result of 3 years of research and development in collaboration with engineers, sleep disorders expert Dr. Claude Gronfier, the medical physicist Ph.D. Olivier Caselles and a group of cognitive scientists. This painstaking work culminated in the right combination of wavelength, timing, diffusion and intensity that makes this patented device so effective.
See, for example, the French publication of Gronfier, Claude: Horloge circadienne et fonctions non visuelles : rôle de la lumière chez l'Homme. Biologie Aujourd'hui 208(4):261-267 (April 2015).
