Red light therapy (photobiomodulation)

What is red light therapy?

Red light therapy uses specific wavelengths of red (typically 620–750 nm) and near-infrared (750–1,100 nm) light. These wavelengths penetrate the skin and are absorbed by the mitochondria, the energy-producing structures in your cells. This process stimulates the production of ATP (adenosine triphosphate), which fuels cellular repair and regeneration.

By working at the cellular level to enhance energy production, red light therapy helps the body repair, restore, and optimise itself naturally — without drugs or invasive procedures.

The full spectrum of benefits

Red light therapy offers a wide range of potential benefits by supporting the body at a foundational, cellular level. Through enhanced mitochondrial function and improved circulation, it can calm inflammation, relieve joint and muscle pain, accelerate wound healing, support athletic recovery, boost energy levels, and contribute to hormonal and reproductive wellness. Because it enhances the body’s natural repair processes rather than introducing chemicals or invasive procedures, red light therapy is appealing if you are seeking a safe, non-invasive, and drug-free approach to whole-body health optimisation.

Red light therapy for pain relief

One of the most well-researched benefits of red light therapy is its ability to reduce inflammation and support tissue repair. It may help individuals experiencing:
– Back pain
– Endometriosis
– Painful periods
– Knee pain
– Shoulder pain
– Achilles tendonitis
– Joint pain
– Arthritis
– Muscle soreness
– Tendon or ligament injuries
– Chronic inflammatory conditions
By improving circulation and cellular repair processes, RLT can help reduce discomfort and accelerate recovery.
 
Red light therapy and digestion

Red light therapy can support gut health by reducing inflammation and promoting cellular repair in the digestive tract. By stimulating mitochondria, the therapy can enhance energy production in gut cells, potentially improving their function and resilience. This increased cellular activity may help maintain the integrity of the intestinal lining, reduce gut permeability, and support a balanced microbiome. Additionally, red light therapy may modulate local immune responses, helping to calm chronic inflammation often associated with digestive disorders such as irritable bowel syndrome or inflammatory bowel disease. While research is still emerging, early studies suggest that incorporating red light therapy could be a complementary strategy for improving digestive wellness.

Hormonal & reproductive health

Red light therapy is gaining attention as a supportive, non-invasive approach to hormonal and reproductive wellness in both women and men. By enhancing mitochondrial function and circulation, it may help reduce inflammation and support healthy cellular activity — key components of hormone balance and fertility.

For women, red light therapy has been explored for supporting ovarian function, egg quality, uterine lining health, and overall pelvic circulation. For men, emerging research suggests red light therapy may help improve sperm motility and overall sperm health by supporting mitochondrial energy production within sperm cells.

Red light therapy with acupuncture

At Brighton Acupuncture, red light therapy is used to amplify the effects of acupuncture by increasing blood flow to treated areas, supporting tissue healing, and prolonging anti-inflammatory benefits after needles are removed.

Integrating red light therapy with acupuncture treatment is an emerging approach that blends modern photobiomodulation with traditional Eastern medicine. Acupuncture works by stimulating specific points on the body to promote energy flow (Qi), circulation, and nervous system balance, while red and near-infrared light therapy supports cellular repair, reduces inflammation, and enhances mitochondrial energy production.
