Light therapy

The Society for Light Treatment (SLTBR) is the specialist research group in this field and holds an annual conference to highlight the most important new research findings. The public areas of the website contain lots of detailed articles on circadian rhythms, melatonin, SAD and sleep.

Rhythms of Life: The biological clocks that control the daily lives of every living thing by Russell Foster and Leon Kreitzman is an up-to-date overview of the whole field by two of the leading researchers. Well-reviewed in Nature and New Scientist.

The best book for SAD, and very readable, is Winter Blues: SAD and how to overcome it by Dr Norman Rosenthal, who first described the condition and looked at light therapy as a treatment. We are naturally pleased to see that we are the only non-US light therapy company that he lists in his book. www.normanrosenthal.com
