These cells then produce cellular energy, which stimulates the body’s natural healing processes. The therapy can be delivered in various ways, including through light boxes, lamps, and wearables.

Benefits of Light Therapy

Light therapy has numerous benefits for the body and mind. It can improve mood, reduce anxiety, and promote relaxation. It can also improve sleep quality, reduce pain and inflammation, and improve skin health. Additionally, light therapy is a safe and non-invasive treatment option that has few side effects.
