Red Light Therapy Precautions

1. Cancer (Active or Untreated)

PBM stimulates cellular activity and blood flow, which could theoretically promote growth in active tumors. People undergoing active cancer treatment should consult their oncologist before starting red light therapy.

2. Photosensitivity Disorders

Conditions like lupus or porphyria, or medications that increase light sensitivity (e.g., some antibiotics, chemotherapy drugs), can make skin more reactive to light. PBM might trigger rashes or irritation in these cases.

3. Pregnancy

There’s limited research on PBM during pregnancy. While it’s generally considered low-risk, it’s usually advised to avoid abdominal or pelvic exposure until more evidence is available.

4. Epilepsy or Seizure Disorders

Some devices emit pulsed or flashing light. People with photosensitive epilepsy should avoid PBM unless the device is confirmed to be safe for them.

5. Severe Thyroid Conditions

Overexposure near the thyroid can affect thyroid activity. People with hyperthyroidism or active thyroid disease should use PBM cautiously and under supervision.

6. Active Infection or Fever

PBM increases local circulation and cellular activity. Applying it over a severe infection or acute fever may worsen inflammation temporarily.

7. Implanted Electronic Devices

Pacemakers or other implanted devices may require caution, especially with certain near-infrared devices that emit strong electromagnetic fields.
