Lux

Lux is a unit of measurement for illuminance. It indicates the amount of visible light that falls on a surface per unit area. In simpler terms, lux measures the brightness of light perceived by the human eye. It helps quantify the intensity of light and is commonly used in lighting design, photography, and other applications where the level of illumination is a crucial factor.

How Is Lux Used in Light Therapy?

Lux is crucial in light therapy as it measures the intensity of light. The recommended lux intensity can vary based on the specific therapeutic goal, whether it’s addressing circadian rhythm disruptions, improving mood, or managing sleep disorders. Monitoring lux levels ensures that individuals receive the appropriate amount of light exposure for the intended therapeutic benefits in a safe and effective manner.
