Is Red Light Therapy Safe? Understanding the potential risks and dangers
Red light therapy is widely recognized as a safe and effective treatment. However, some risks and contraindications should be considered before use. While side effects are rare, knowing potential risks helps ensure safe and effective therapy.
This article explores red light therapy safety, possible dangers, and who should avoid using it.
Red light therapy has been used safely for over five decades. Millions of people have benefited from both laser and LED treatments with minimal side effects.
Experts like James Carroll, a leading researcher in photobiomodulation, have used full-body red light therapy for decades. His research and practical experience confirm that long-term use does not lead to harmful effects.
Studies show that red light therapy reduces inflammation, enhances energy production, and speeds up recovery. These benefits contribute to better overall health and longevity.
There is little evidence of long-term negative effects. Most users experience cumulative benefits over time. However, overstimulation of cellular processes may lead to unknown effects, and further research is needed.
One of the biggest concerns with red light therapy is its use in cancer patients. While some studies suggest it may help manage cancer treatment side effects, there is no conclusive evidence on its safety for active tumors.
Key Considerations for Cancer Patients:
Red light therapy devices sometimes use pulsing light, which can trigger seizures in people with epilepsy.
How to Reduce Risk:
Some medications cause light sensitivity, increasing the risk of skin irritation or discomfort when exposed to red light therapy.
Common Photosensitive Medications:
Red light therapy can stimulate thyroid function, which benefits hypothyroidism but may worsen symptoms in hyperthyroid patients.
If you have hyperthyroidism, avoid using red light therapy directly on your neck without medical advice.
Red light therapy boosts immune function and reduces inflammation, but in rare cases, it may overstimulate the immune system. If you have an active infection, chronic fatigue, or an autoimmune disorder, start with low doses and increase gradually.
While red light therapy is generally safe, some people experience mild side effects, especially with overuse.
Some people report feeling tired after sessions, especially when using high doses. If this happens, reduce treatment time or stand farther from the light.
Bright red and near-infrared light can cause headaches or eye discomfort in some people. If this happens:
Some individuals are naturally more sensitive to light therapy. If you experience discomfort, start with shorter sessions and lower intensity.
To minimize risks and maximize benefits, follow these best practices:
More light does not always mean better results. Overuse may cause mild side effects. Stick to recommended treatment times.
Stand 6-12 inches away from your device.
If using high-powered panels, increase the distance to prevent skin sensitivity.
Although red light therapy does not damage the eyes, prolonged exposure may cause discomfort. Protective goggles are recommended for sensitive individuals.
If you have cancer, epilepsy, or are on medication, consult your doctor before starting red light therapy.
Red light therapy is a safe and effective treatment for most people. Risks are minimal when used correctly. However, individuals with certain conditions, like cancer, epilepsy, or hyperthyroidism, should take extra precautions.
By following best practices, you can safely enjoy the healing benefits of red light therapy with minimal risk.
There is no evidence that red light therapy causes cancer. Some studies suggest it may even help reduce cancer treatment side effects. However, if you have active cancer, consult your doctor.
“Most studies showed that no side effects were observed with the use of [red light therapy]. The results of this systematic review, based on current literature, suggest that the use of [red light therapy] in the prevention and management of cancer treatment toxicities does not lead to the development of tumor safety issues.”
No. Red light therapy does not emit UV rays, so it cannot cause sunburn or skin cancer.
Some people may experience headaches due to bright light exposure. If this happens, try wearing protective eyewear and reducing session time.
Red light therapy is safe for the eyes but may cause strain with prolonged exposure. If you feel discomfort, use eye protection or avoid direct exposure.
No, diabetics can benefit from red light therapy, as it helps reduce inflammation and improves circulation. However, they should monitor their blood sugar levels closely.
Red light therapy is one of the safest non-invasive treatments available today. By understanding its risks and following best practices, you can enjoy all the benefits while minimizing potential side effects.
