One of the treatments I use for general therapy for depression is "Sun-sitting." For 15-20 minutes in the morning or maybe evening, too, I recommend people sit facing the sun wearing as few clothes as possible. Some people actually gaze at the sun, so that has to be done only when the sun is first arising or setting as too intense sun can cause eye problems. I recommend closing your eyes and facing the sun. You can do this outside or behind a glass door or window. We know the sun helps make vitamin D3 in the skin, so this might be a factor in improving health, because most people are low in vitamin D in their body. People who live far from the equator with less sunlight are known to develop depression more easily. Sun sitting is also a nice quiet time of relaxing and getting in touch with nature.
