Melatonin seem to help SAD when taken PM says B J  Sahley in The Melatonin Report 1-800-669-CALM
Melatonin for insomnia, St John's wort for depression, 5-HTP for brain serotonin, +  full-spectrum light bulb therapy or outdoor natural light will all reduce SAD and affect our inner body clock.  The SCN (suprachiasmatic nucleus) cluster of nerve cells in the brain registers even the faint dawn light that filters through the eyelids as we sleep.  winter 2002 newsletter
UV lighting for SAD - (2002-2004)
Sun therapy was very popular in Europe at the turn of the century, and until the late 1930's. It was known as heliotherapy, named after the Greek God of the sun - Helios. By mid 1930's, sunbathing and UV therapy was most effective treatments for many infectious diseases such as: lupus, eczema, acne, herpes, rheumatoid arthritis, gout, cystics, anemia, colitis, kidney problems, etc.
Then in 1938, penicillin was discovered, and world turned to pharmaceuticals, and drugs became big business. Sun therapy was then regarded as medical quackery.
There is another side to the healing with light - and most do not know the tremendous health benefits from UV. UV light activates the synthesis of Vitamin D, which is a prerequisite for absorption of calcium and other minerals.
UV light can lower blood pressure; can increase efficiency of the heart, can improve EKG readings and blood profiles; can reduce cholesterol; can increase the level of sex hormones (Vita-Lite has a balanced UV, and is used extensively for enhancing the mating and reproduction of indoor pet and animals); UV activates an important skin hormone - solitrol (works with Melatonin to generate changes in mood, circadian rhythms, and seasonal reproduction.)...
How (natural or Full Spectrum) Light Therapy Works - As light enters the eyes, millions of light and color sensitive cells called photoreceptors convert the light into electrical impulses. These impulses travel along the optic nerve to the brain where they tripper the hypothalamus gland to send chemical messengers called neurotransmitters to regulate the automatic functions of body. The hypothalamus is part of the endocrine system whose secretions govern most bodily functions - blood pressure, body temperature, breathing, digestion, sexual function, moods, immune system, aging process, and circadian rhythm. Full spectrum lighting (containing all wavelengths) sparks the delicate impulses that regulate these functions and maintain health...
[Caution needs to be taken re UV (fluorescent) bulb disposal and (excessive) light exposure (esp. artificial).]
"Large amounts of (artificial) UV are harmful, however, in trace amounts, it is very beneficial. Sunlight contains large amounts of UV in various wavelengths. Each wavelength is responsible for various things, such as tanning response in humans, activate synthesis of Vitamin D, and absorption of calcium and other minerals. "
