Red Light Therapy & Depression: What the Research Shows

Red light therapy has gained attention in recent years for its potential role in mood and brain health. Unlike UV rays, red light uses low-level wavelengths that can penetrate the skin and stimulate cellular activity.

Emerging research suggests red light may help regulate circadian rhythms, reduce inflammation, and even improve symptoms of depression. Some studies have found it can enhance energy, stabilize mood, and support better sleep —all of which are critical for mental health.

While red light therapy isn’t a replacement for professional treatment, it can be a supportive tool alongside other strategies. Devices range from small handheld units to larger panels used in wellness centers.

✨ Takeaway: Red light therapy is a promising, science-backed tool that may support mood and resilience—but it works best as part of a holistic approach to mental health.
