From post-ride muscle care to everyday comfort, discover the research behind red and near-infrared light therapy — and why it's attracting attention in the equestrian world.

You invest in the best feed. You pay attention to saddle fit. You spend hours ensuring your horse has the right training, conditioning, and care.

But what about recovery?

Every ride asks something of your horse's body. From the muscles supporting the back to the joints and tendons working through every stride, even seemingly effortless movement requires a remarkable amount of physical coordination.

And while we're quick to notice when something is wrong, there's a growing conversation in equine care about what we can do to support our horses before discomfort becomes an obvious problem.

That's where red light therapy comes in.

Once associated primarily with professional rehabilitation settings, light-based therapies are becoming increasingly familiar to everyday horse owners.

But is there real science behind them?

Yes — and the strength of the evidence depends on the type of light therapy, the device, and the intended application.

Researchers have investigated everything from muscle activation and exercise-related physiological responses to how therapeutic light actually penetrates a horse's skin.

Here's what they've discovered, and what it could mean for the way we care for our horses.

Your Horse's Muscles Work Harder Than You Might Think

Whether your horse is schooling, jumping, hacking, or simply moving around the paddock, its musculoskeletal system is constantly working.

The back helps transfer movement between the forehand and hindquarters. The hindquarters generate propulsion. The hocks, tendons, and supporting soft tissues help manage substantial forces during movement.

And just like human athletes, horses need appropriate recovery between periods of physical activity.

This is one reason light-based therapies have attracted interest within equine sports medicine.

Rather than relying primarily on external heat or mechanical pressure, photobiomodulation uses specific wavelengths of light to influence biological activity within tissues.

Research suggests that appropriately delivered red and near-infrared light can interact with cellular processes involved in energy production and signaling.

That has prompted researchers to investigate whether therapeutic light might complement established approaches to muscle care and rehabilitation.

What Happens When Red Light Reaches the Body?

Every cell in your horse's body depends on energy to function.

Much of that energy is produced inside mitochondria, which help generate a molecule known as adenosine triphosphate, or ATP.

Think of ATP as one of the body's essential energy currencies.
