Well, bright light therapy is where we use light that is the same intensity, color, and wavelength of sunlight.

Bright light therapy, traditionally, was used for seasonal affective disorder (SAD). When someone, because of not getting very much sunlight exposure, may get depressed in the winter time. And then when there's increased light exposure, may even get manic or hypomanic in the spring time.

Sunlight is an essential ingredient for a healthy lifestyle, but many of us don’t get the amount of daylight we need to feel its benefits.

Our sunlight lamp aim to mimic the extra hours of sunlight from spring and summer that you don't get in fall and winter. It helps you fight depression, sleep disorders, and low moods on rainy days.

Intensity: The intensity of the light box is recorded in lux, which is a measure of the amount of light you receive. For winter blue, the typical recommendation is to use a 10,000-lux light therapy lamp.

Distance: You would hold it at least an arm's distance，about 16 to 24 inches (41 to 61 centimeters) from your face.

Angle of Gaze: To avoid aversive visual glare, the light therapy box should project downward towards the eyes at an angle, at like a 45 degree angle to your eyes.

Duration: You would use it for 15 to 30, or even perhaps 45 minute, intervals or increments, and that would be a session.

Timing: For most people, light therapy is most effective when it's done early in the morning, after you first wake up.
