Photobiomodulation

A process where specific wavelengths of light stimulate biological tissues, promoting cellular repair and reducing inflammation. This principle is increasingly studied for therapeutic lighting applications.

Entrained Rhythm

The synchronization of an individual’s circadian clock with external cues, such as light, temperature, and meal timing. Proper entrainment promotes health and alignment with the 24-hour day.

Biological Darkness

A lighting condition achieved by removing wavelengths in the 440-495nm range, simulating darkness for the circadian system while maintaining functional light for visibility.

SCN (Suprachiasmatic Nucleus)

The part of the brain that maintains the body’s circadian rhythm, significantly influenced by light exposure.

Melanopsin

A photopigment in the eye sensitive to blue light, playing a crucial role in regulating sleep and circadian rhythms.

Blue Light Hazard

The risk associated with blue light exposure, particularly its potential to damage the retina and disrupt sleep patterns.

Blue Light

High energy light between 440nm and 495nm, which signals to the eye to suppress melatonin and other hormones to trigger biological wake up and alertness. Absence of blue light signals recovery and rest.
