Light therapy works well beyond winter. A 2025 JAMA Psychiatry meta-analysis of 11 trials and 858 patients found 40.7% remission with bright light versus 23.5% with control in nonseasonal depression. Two hosts cover the standard dose — 10,000 lux from a UV-filtered box, 20 to 30 minutes in the early morning, 12 to 24 inches from the face — when it's reasonable to push to 60 minutes, and who shouldn't start without a conversation first.
