Light therapy uses artificial light that mimics sunlight to help with various conditions. Research shows it can help with things like seasonal affective disorder (SAD), jet lag, sleep disorders, adjusting to working at night, etc. 

The intensity of the light therapy lamps is recorded in lux, which is a measure of the amount of light you receive. For SAD (which is a type of seasonal depression that occurs at certain times each year, usually in the fall or winter) the typical recommendation is to use a 10,000 lux light box at a distance of about 16 to 24 inches (41 to 61 centimeters) from your face for maximum effectiveness.

Light therapy is also best when done for 20 to 30 minutes, usually in the morning on a daily basis.

The lamp I’m using in the video is the Carex Day-Light Classic Plus Bright Light Therapy Lamp. It’s a full-spectrum sunlight lamp that provides 10,000 lux of light on the high setting.
