Is Red Light Therapy Effective for Muscle Recovery and Sports Injuries?
20.07.25
From professional athletes to weekend warriors, recovery is the key to consistent performance. But finding safe, non-invasive ways to bounce back faster can be a challenge. That’s where red light therapy enters the picture. With growing interest among physiotherapists, sports teams, and fitness lovers alike, the big question is: Can red light therapy actually help with muscle recovery and sports injuries?
What is Red Light Therapy?
Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation, is a non-invasive treatment that uses specific wavelengths of red and near-infrared light to stimulate cellular activity. These wavelengths penetrate the skin and are absorbed by mitochondria — the energy-producing components of our cells — helping to boost ATP (adenosine triphosphate) production, which fuels cell repair, regeneration, and overall function.
Baxter Blue’s Red Light Therapy devices are designed with these wavelengths in mind, combining multiple clinically backed nanometers — including red (630nm, 660nm) and near-infrared (810nm, 830nm, 850nm) — in each device. These wavelengths penetrate deep into the skin, muscles, and even joints, where they stimulate energy production in the cells (via the mitochondria), increase circulation, reduce inflammation, and support tissue repair.
The Science Behind Muscle Recovery
Here’s how red light therapy helps after physical activity or injury:
Reduces inflammation and oxidative stress - After intense exercise or an injury, inflammation is part of the body’s natural response. Red light therapy has been shown to help regulate pro-inflammatory cytokines and reduce oxidative damage to cells.
Improves blood flow and oxygenation – Better circulation = faster nutrient delivery and waste removal. This supports quicker muscle recovery and reduced soreness.
Stimulates mitochondrial function- Light energy helps produce more ATP (cellular energy), which your muscles need to repair and rebuild post-exercise.
Reduces DOMS (Delayed Onset Muscle Soreness) - Red light therapy has been shown to reduce post-workout soreness and stiffness when used after training.
What the Research Says
1/ A 2014 study published in Laser Therapy found that red light therapy significantly reduced muscle soreness and improved recovery in athletes post-exercise compared to placebo groups.
2/ A 2016 review in Journal of Biophotonics concluded that photobiomodulation improved muscle performance and accelerated recovery when applied before or after exercise.
3/ A 2021 study found that near-infrared light improved recovery following eccentric exercise (which typically causes muscle damage), reducing markers of inflammation and soreness.
Who Can Benefit?
Red light therapy isn’t just for elite athletes. It can support recovery for:
1/ Runners, cyclists, and endurance athletes
2/ Weightlifters and gym goers
3/ Sports teams (e.g. football, netball, soccer)
4/ People recovering from injury or surgery
5/ Those with muscle tightness or chronic overuse injuries
6/ Weekend warriors and active lifestyles
How to Use Red Light Therapy for Recovery
1/ After exercise: Use your red light therapy device within 2 hours post-workout for best results. Apply to major muscle groups used during training.
2/ For injury or inflammation:Target the affected area for 10–15 minutes per session, up to 5x per week.
3/ Distance from device: Sit or stand 15–30cm away from the panel. Consistent exposure is more important than intensity.
4/ Be consistent: Aim for at least 4–5 sessions per week to maximise results. Like training, recovery is cumulative.
Why Athletes Trust Baxter Blue
Our red light devices are trusted by leading wellness experts and designed to help you recover faster, feel better, and perform at your best. With five clinically backed wavelengths (630nm, 660nm, 810nm, 830nm, and 850nm), our panels target different depths of the body—making them ideal for both surface-level muscle repair and deeper joint and tissue recovery.
Final Thoughts
Red light therapy offers a powerful, science-backed solution for anyone looking to recover smarter—not just harder. Whether you're managing post-workout soreness, healing a sports injury, or simply trying to stay active without setbacks, red light therapy can be an effective addition to your recovery toolkit.
