Effects of Near Infrared Light on Surgical Wound Healing (2026)

This study reviewed the role of near-infrared (NIR) light / photobiomodulation (PBM) in improving post-surgical wound healing. The authors evaluated evidence on how NIR therapy affects tissue repair, inflammation, and recovery after surgery.

Key findings:

  • Enhanced wound healing: NIR light showed potential to accelerate healing by improving cellular repair and tissue regeneration.
  • Reduced inflammation: PBM may help lower inflammatory responses that can delay healing.
  • Pain relief: NIR therapy may reduce postoperative discomfort and support recovery.
  • Improved circulation & cell activity: Benefits are thought to come from increased mitochondrial activity, ATP production, and better local blood flow.

Conclusion:

The paper suggests near-infrared photobiomodulation is a promising non-invasive adjunct for surgical wound healing, but clinical outcomes depend on treatment parameters such as wavelength, dosage, and timing. More standardized clinical evidence is still needed.
