The health benefits of light therapy are expanding its use beyond winter depression. Here we explore those promises and pitfalls, including ADHD, PTSD, bipolar depression, binge eating, sleep disorders, dementia, sexual dysfunction, traumatic brain injury, diabetes, and arthritis.

This first-of-its-kind study looked at lightbox in PTSD with a randomized, placebo-controlled design.
