Who Should Avoid Red Light Therapy?


Have you heard about the incredible benefits of red light therapy? From skin care to pain management, this innovative treatment has gained popularity for enhancing various aspects of health and well-being. However, while red light therapy offers numerous advantages, not everyone may benefit. This article will explore who should avoid red light therapy and why, ensuring you comprehensively understand its limitations.

Understanding Red Light Therapy

Red light therapy, or low-level laser therapy (LLLT) or photobiomodulation (PBM), involves exposing the body to red or near-infrared light. This therapeutic approach harnesses specific wavelengths of light to stimulate energy production within the body’s tissues. By enhancing cellular metabolism, red light therapy facilitates various physiological responses, including reduced inflammation, accelerated tissue repair, and improved circulation. Red light therapy can be applied to many applications, including wound healing, pain management, skin rejuvenation, and muscle recovery. With its gentle and painless nature, red light therapy offers a safe and effective alternative for individuals seeking natural methods to support their health and well-being. Whether used as a standalone treatment or in combination with other modalities, red light therapy continues to gain recognition for its versatility and potential to enhance overall vitality and quality of life.

Who Should Avoid Red Light Therapy?

While red light therapy is generally safe for most individuals, certain groups may need to exercise caution or avoid it altogether. Here’s a closer look at who should proceed with care:

Pregnant Women

Expectant mothers should consult with their healthcare providers before undergoing red light therapy. Although research on the effects of red light therapy during pregnancy is limited, it’s essential to err on the side of caution. Some experts advise against exposing the developing fetus to unnecessary light therapy, especially during the first trimester when organogenesis occurs.

Individuals with Photosensitivity

People with photosensitivity disorders, such as certain types of porphyria or lupus erythematosus, should avoid red light therapy. Photosensitivity causes an abnormal reaction to light exposure, leading to skin rashes, blistering, or other adverse effects. Since red light therapy involves exposure to specific wavelengths of light, it may exacerbate symptoms in individuals with photosensitive conditions.

Cancer Patients Undergoing Radiation Therapy

While red light therapy shows promise in managing certain side effects of cancer treatment, such as radiation-induced dermatitis, cancer patients must consult their oncologists before considering this therapy. Radiation therapy targets cancer cells by damaging their DNA, and exposing the treatment area to additional light may interfere with the efficacy of radiation treatment. Therefore, cancer patients should seek guidance from their healthcare team to ensure compatibility between red light therapy and their current treatment plan.

Individuals with Eye Conditions

Since red light therapy involves exposure to light, individuals with certain eye conditions or those at risk of retinal damage should approach this treatment cautiously. Prolonged or intense exposure to bright light, including red or near-infrared light used in therapy, may exacerbate eye conditions such as macular degeneration or retinitis pigmentosa. Before proceeding, individuals with eye disorders must discuss red light therapy’s potential risks and benefits with their ophthalmologists.

People Taking Photosensitizing Medications

Certain medications, such as antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), diuretics, and some antidepressants, can increase the skin’s sensitivity to light. These drugs are known as photosensitizing agents and may heighten the risk of adverse reactions to red light therapy, such as sunburn-like symptoms or phototoxicity. Individuals taking photosensitizing medications should inform their healthcare providers before undergoing red light therapy to mitigate potential risks.


While red light therapy offers many benefits for many individuals, it’s essential to recognize that it may not suit everyone. Pregnant women, individuals with photosensitivity disorders, cancer patients undergoing radiation therapy, those with eye conditions, and people taking photosensitizing medications should exercise caution or avoid red light therapy altogether. Schedule a consultation with Mesa Medical Health & Wellness, and we can help ensure safety and optimize outcomes.
