Red light therapy (RLT), also known as low-level laser therapy (LLLT), is a treatment that uses specific wavelengths of light to promote healing and reduce inflammation. While research is ongoing, here are some potential uses and benefits of RLT related to cardiovascular health, particularly in addressing artery plaque:
Potential Benefits of Red Light Therapy
- Improved Circulation: RLT may enhance blood flow, which can help in delivering nutrients and oxygen to tissues and removing waste products.
- Reduction of Inflammation: Chronic inflammation is a contributor to arterial plaque buildup. RLT has anti-inflammatory properties that might help reduce inflammation in the arteries.
- Endothelial Function: Some studies suggest that RLT can improve endothelial function, which is crucial for maintaining vascular health and preventing plaque formation.
- Cellular Repair and Regeneration: RLT can stimulate cellular processes that promote healing and tissue regeneration, potentially aiding in the repair of damaged arteries.
- Oxidative Stress Reduction: RLT may help reduce oxidative stress, which plays a role in the development of atherosclerosis (plaque buildup in arteries).
Current Research and Considerations
Consult Healthcare Professionals: Always consult with healthcare providers before starting any new therapy, especially for serious conditions like cardiovascular disease.
Limited Clinical Evidence: While there are promising studies, conclusive clinical evidence specifically linking RLT to the reversal of artery plaque is limited.
Complementary Therapy: RLT should be considered as a complementary therapy rather than a standalone treatment. Lifestyle changes such as diet, exercise, and medical interventions are essential for managing cardiovascular health.

20 minutes of light therapy (per day) was superior to lovastatin in reducing both the cholesterol and LDL levels as well as the plaque formation (26.4%).

Researchers have been examining the large list of benefits of red light therapy including reducing inflammation; as evidenced by studies that have demonstrated substantial benefits as an anti-inflammatory treatment across several health conditions, such as heart disease.

Atherosclerosis, which currently contributes to 31% of deaths globally, is of critical cardiovascular concern. Current diagnostic tools and biomarkers are limited, emphasizing the need for early detection. Lifestyle modifications and medications form the basis of treatment, and emerging therapies such as photodynamic therapy are being developed. Photodynamic therapy involves a photosensitizer selectively targeting components of atherosclerotic plaques. When activated by specific light wavelengths, it induces localized oxidative stress aiming to stabilize plaques and reduce inflammation. The key advantage lies in its selective targeting, sparing healthy tissues. While preclinical studies are encouraging, ongoing research and clinical trials are crucial for optimizing protocols and ensuring long-term safety and efficacy. The potential combination with other therapies makes photodynamic therapy a versatile and promising avenue for addressing atherosclerosis and associated cardiovascular disease. The investigations underscore the possibility of utilizing photodynamic therapy as a valuable treatment choice for atherosclerosis. As advancements in research continue, photodynamic therapy might become more seamlessly incorporated into clinical approaches for managing atherosclerosis, providing a blend of efficacy and limited invasiveness.
