I found these interesting links when googling light therapy:

indoor plants/herb therapy - to enhance cooking therapy (integral/complementary?)

we could talk more about this in chemistry - light

When NASA determined that red LEDs could grow plants in space, Marshall Space Flight Center awarded QDI several
Small Business Innovation Research (SBIR) contracts to investigate the effectiveness of the
broad-spectrum diodes in medical applications. The contracts, issued from 1995 to 1998, focused on increasing energy inside human cells. It was NASA’s hope that the LEDs would not only yield medical benefits on Earth, but that they would help to stem the loss of bone and muscle mass in astronauts, which occurs during long periods of weightlessness. (In space, the lack of gravity keeps human cells from growing naturally.) Furthermore,
since wounds are slow to heal in a microgravity environment, LED therapy could accelerate healing and keep what would be termed as minor wounds on Earth from becoming mission-catastrophic in space.
In addition to promoting cell growth, the red LEDs are capable of activating light-sensitive, tumor-treating drugs that, when injected intravenously,
could completely destroy cancer cells while leaving surrounding tissue virtually untouched. The technique, approved by the U.S. Food and Drug Administration (FDA) for use in laboratory and human trials, is known as
Photodynamic Therapy.
Could we please talk about this in chemistry - or is it biology more - or is it physics then? which class - or all? I'm glad to be in all three at once!
