Reduce Pain with Red-Light Therapy

When tissue is injured or stressed, the body triggers inflammation—releasing cytokines, increasing oxidative stress, and recruiting immune cells to the area. While necessary for healing, chronic or excessive inflammation can cause pain, swelling, and slow recovery.

Red and near-infrared light penetrate tissue and interact with mitochondria, which influences the cell’s biochemical environment and inflammatory signaling pathways.

• Red-light therapy increases ATP production and restores mitochondrial balance.
• It also reduces the buildup of reactive oxygen species (ROS)—molecules that drive oxidative stress and tissue damage.
• Lower oxidative stress means less activation of inflammatory genes.

Research shows RLT downregulates pro-inflammatory cytokines (like TNF-α, IL-1β, and IL-6) and upregulates anti-inflammatory cytokines (like IL-10).

• This shift helps resolve inflammation faster while still allowing necessary immune activity.

By increasing nitric oxide release and vasodilation, RLT improves blood flow, which speeds the removal of inflammatory byproducts and supports tissue repair.

• Hamblin MR (2017) – RLT modulates inflammation by balancing pro- and anti-inflammatory cytokines, reducing oxidative stress, and enhancing tissue repair.
• Chung H et al. (2012) – Demonstrated that photobiomodulation decreases inflammatory markers and improves healing in both acute and chronic injury models.
• Silveira et al. (2016) – Found that RLT significantly reduced muscle inflammation and oxidative stress after strenuous exercise.
• Alves et al. (2014) – Showed reduced swelling, pain, and inflammatory cell activity in animal models treated with RLT.

✅ In short: Red-Light Therapy reduces inflammation by restoring mitochondrial function, lowering oxidative stress, rebalancing immune signaling, and improving circulation—helping your body recover faster and feel better.
