What Is Photobiomodulation? Exploring the Benefits of High-Intensity Laser Therapy

At FlySpace, we're always looking for innovative, evidence-based tools to support healing and enhance performance. One of the most exciting additions to our practice is high-intensity laser therapy (HILT)—a powerful form of photobiomodulation that helps accelerate recovery, reduce pain, and support tissue healing at the cellular level. 

But what exactly is photobiomodulation, and how does high-intensity laser therapy work? 

What is Photobiomodulation? 

Photobiomodulation (PBM) is a non-invasive therapy that uses specific wavelengths of light to stimulate biological processes in the body. This light—typically in the red or near-infrared spectrum—penetrates the skin and is absorbed by cells, where it influences healing and cellular function. 

Unlike surgical lasers, PBM does not heat or damage tissue. Instead, it helps optimize how cells function—making it a gentle but powerful way to support the body’s natural recovery process. 

The Science Behind It 

The key player in photobiomodulation is a part of the cell called the mitochondria—often called the cell’s "powerhouse." When laser light is absorbed by the mitochondria, it stimulates the production of ATP (adenosine triphosphate), which is the energy currency cells use to function and repair themselves. 

Increased ATP production means cells can: 

• Heal more efficiently 

• Reduce inflammation 

• Decrease pain signaling 

• Promote tissue regeneration 

Why High-Intensity Laser? 

High-intensity laser therapy (HILT) delivers the same therapeutic wavelengths as traditional low-level lasers but at a higher power, which allows the light to penetrate deeper into the body—reaching muscles, tendons, joints, and even bone. 

This deeper penetration allows HILT to be especially effective for: 

• Chronic pain conditions (e.g., arthritis, tendinopathy) 

• Acute injuries (e.g., sprains, strains) 

• Nerve-related pain 

• Post-surgical healing 

• Athletic recovery and performance 

What You Can Expect 

HILT sessions are quick, comfortable, and completely non-invasive. Patients often report a gentle warming sensation in the area being treated. Most importantly, many notice a reduction in pain, improved mobility, and faster recovery after just a few sessions. 

The Bottom Line 

Photobiomodulation through high-intensity laser therapy is an exciting advancement in physical therapy and rehabilitation. It supports the body at a cellular level—enhancing healing, reducing pain, and helping you get back to doing what you love, faster.
