Cue the Ned Stark meme: Winter is coming. Light therapy lamps help people who suffer from seasonal affective disorder cope with the symptoms. That’s why search interest increases in winter months.
What’s next: Interest in light therapy has been particularly strong as the lamps become better known to the public and as more people realize the debilitating effects of seasonal affective disorder.
The light therapy market is expected to grow at a ~5% CAGR from about $800m in global revenue in 2018, to more than $1B in 2025. With prescription drugs increasingly under fire for their price and dangers, light therapy will be recognized more and more as an alternative.
