However, here is how it works. Light therapy is a complex procedure involving a visit to a doctor. You could, of course, buy a light therapy box over-the-counter. But, it would be better if you consult your doctor before going ahead with the treatment all by yourself. When you visit the clinic, you are made to sit with your face towards a light box, which has bulbs or tubes of light in it, covered with a plastic screen that helps block out harmful ultraviolet rays that can cause cataracts or skin problems. You look at the box but not at the light directly because the light can be damaging. The intensity of the light from the box is recorded in lux, which is a way of measuring the amount of light that one receives at a specific distance. These light boxes produce between 2,500 lux to 10,000 lux.
Just to give you an idea, the lighting in an average living room is less than 400 lux and being in a bright sunny day may register 100,000 lux. These sessions involve daily sittings of 15-30 minutes at first and could go up to two hours, over time. But, if your skin is sensitive to light, or if you are taking antibiotics or anti-inflammatory medicines, or if your eyes are vulnerable to light damage, don’t try this at all!
