Research suggests that red and near-infrared light (630-850nm) may help regulate immune system activity, reduce inflammation, and improve symptoms of autoimmune diseases. RLT has been studied for its potential to modulate immune response, reduce oxidative stress, and support cellular repair in autoimmune conditions like rheumatoid arthritis, lupus, and multiple sclerosis (MS).
Key Findings from Multiple Studies:
- A 2017 study found that red light therapy reduced joint inflammation and pain in individuals with rheumatoid arthritis.
- A 2019 clinical trial suggested that near-infrared light (810nm) helped improve fatigue and muscle function in patients with multiple sclerosis (MS).
- A 2021 review showed that RLT modulated immune system activity, helping to reduce flare-ups in autoimmune conditions like lupus and psoriasis.
- Research indicates that red light therapy helps regulate inflammatory cytokines, which play a key role in autoimmune disease progression.
Implications:
These findings suggest that red light therapy between 630-850nm may be beneficial for individuals managing autoimmune diseases by reducing inflammation, alleviating symptoms, and supporting immune system balance. While not a cure, RLT may be a complementary therapy for managing autoimmune conditions.
