Dawn simulation generally uses light sources that range in illuminance from 100 to 300 lux, while bright light boxes are usually in the 10,000-lux range. Approximately 19% [4] of patients discontinue post-awakening bright light therapy due to inconvenience. Because the entire treatment is complete before awakening, dawn simulation may be a more ...
Typical measurements of light have used a Dosimeter. Dosimeters measure an individual's or an object's exposure to something in the environment, such as light dosimeters and ultraviolet dosimeters. In order to specifically measure the amount of light entering the eye, personal circadian light meter called the Daysimeter has been developed. [11]
Bright light therapy is a treatment method that involves exposure to a high-intensity light source that mimics natural sunlight, says Frank A. Ghinassi, Ph.D., senior vice president of Behavioral ...
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.

Artificial sunlight is useful in treating and preventing seasonal affective disorder (also known as winter depression, which causes depression symptoms specifically in winter), [3] and delayed sleep phase syndrome, in which the circadian rhythm (the rhythmic alternation between daylight and nighttime behavior and bodily states) is disturbed and the person falls asleep much later than he or she ...
However, if you can’t get out in the sun, consider using a 10,000-lux light therapy lamp, which can mimic daylight and help signal your brain to wake up. 6. Move Your Body
The timing of these patterns is set by the 24-hour light–dark cycle. In particular, short-wavelength "blue" light in the daylight spectrum has maximal effect on human circadian rhythms. Research has shown that when these patterns are disrupted, individuals are more susceptible to ailments such as breast cancer, obesity, sleep deprivation ...
