Light therapy

Has anyone tried light therapy. I try to get outside for a little each day but am thinking of buying a light box. Anyone know why some are blue light and some are full spectrum? Anyone know of any good links online? Thanks for your help.

I know this can help a lot if one tends to experience a little more depressive symptoms, particularly in the winter months. Sunlight is also helpful in the production of vitamin D in the body.

This is a link to a little description of some of the benefits of sunlight: http://jenaisle-candidthoughts.blogspot.com/2008/11/sunlight-and-it... This link is a more scientific and extensive discussion of the benefits of sunlight: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2290997/

This link is to a very good research report on the benefits of light therapy, including conclusions regarding effectiveness of light type, timing of use, etc.: http://www.health.am/psy/more/light_therapy/

If you have done or in the future do, make use of light therapy, I'd really love to hear about it! Good luck!
