The Science Behind Photobiomodulation - Laser Therapy in Dogs and Cats
Photobiomodulation — the science behind laser therapy — uses red and near-infrared light to stimulate healing, reduce inflammation, and relieve pain. It is a non-invasive, drug-free modality that can be used alongside conventional treatment
How Photobiomodulation Therapy Reduces Pain
Increases nitric oxide → improves blood flow and healing
Boosts endorphins → natural pain relief
Balances ion channels → nerves function normally again
Reduces bradykinin → less inflammation and swelling
Increases serotonin → improves mood and comfort
Releases acetylcholine → helps muscles relax
Stabilizes nerve signals → stops pain messages from firing
Blocks pain nerve activity (C-fibers) → reduces pain sensation
Result: The body naturally achieves analgesia (pain relief) and faster healing.
How Photobiomodulation Therapy Speeds Up Healing
Activates white blood cells (leukocytes): Cleans up damaged tissue and fights infection
Stimulates new blood vessel growth: Improves circulation and delivers nutrients faster
Promotes new cell growth: Repairs skin, muscle, and tissue sooner
Strengthens healing tissue: Improves flexibility and reduces scarring
Boosts fibroblast activity: Helps form healthy new connective tissue
Accelerates wound closure: Shortens recovery time for injuries or surgery
Result: Laser therapy helps your pet heal faster, stronger, and more comfortably.
How Photobiomodulation Therapy Reduces Inflammation
Activates cell energy (ATP): Helps damaged cells repair faster
Improves blood flow (vasodilation): Brings oxygen and nutrients to injured tissue
Balances inflammation signals: Reduces overactive immune response
Lowers heat and swelling: Calms irritated tissues naturally
Boosts immune cells: Strengthens the body’s healing response
Balances cellular ions (Ca, Na, K): Keeps cells stable and healthyResult: Laser therapy helps the body control inflammation, reduce swelling and pain, and speed up recovery — all without drugs or discomfort.
