Red light therapy is praised for its wide range of health benefits—from skin rejuvenation and wound healing to pain relief and improved sleep. But is it safe for everyone?
While red light therapy is generally considered non-invasive and low-risk, there are certain groups of people who should avoid or be cautious about using it. In this article, we’ll explore who shouldn’t use red light therapy, and why.
1. People with Light Sensitivity (Photosensitivity)
Those who have photosensitivity—a heightened sensitivity to light—may experience skin irritation, rash, or discomfort from red or near-infrared light exposure.
Common causes of light sensitivity include:
-
Lupus or other autoimmune diseases
-
Certain medications (e.g., antibiotics, retinoids, diuretics)
-
Genetic conditions like porphyria
Tip: Always check with a doctor if you’re taking medications that affect light sensitivity.
2. Pregnant Women (Use with Caution)
There is no strong evidence suggesting red light therapy is harmful during pregnancy. However, due to the lack of large-scale studies, it’s often recommended to avoid red light therapy on the abdomen or lower back during pregnancy as a precaution.
Tip: Consult a healthcare provider before starting red light therapy while pregnant.
3. People with Active Cancer or Tumors
Some experts suggest caution when using red light therapy on or near malignant tumors, as light may stimulate cellular activity. While no direct link has been proven, it’s advised to avoid red light therapy on cancerous areas unless under medical supervision.
Tip: Cancer patients should always seek approval from their oncologist before beginning therapy.
4. People with Severe Eye Conditions
Although red light therapy can help with eye strain and retinal support in controlled environments, direct exposure of red or near-infrared light to the eyes—especially from high-powered LED devices—may be risky without proper eye protection.
Tip: Always wear protective goggles during facial treatments or when using full-body light beds.
5. Individuals with Epilepsy (Light-Induced Seizures)
People with photosensitive epilepsy may be at risk if exposed to certain light flicker frequencies, even though most red light therapy devices do not flash or flicker like strobe lights.
Tip: Check the specifications of your device and consult a neurologist if you have a history of seizures.
Conclusion: Is Red Light Therapy Safe for You?
Red light therapy is safe for most people, but there are exceptions. You should avoid or consult a medical professional before using red light therapy if:
-
You’re pregnant
-
You have active cancer
-
You are sensitive to light or on photosensitizing medication
-
You have epilepsy or serious eye conditions
When in doubt, always talk to a healthcare provider—especially if you have any pre-existing health conditions.
