Spring brings a specific kind of enthusiasm. The weather is better, you want to be outside more and you are probably asking more of your body than you have been doing for months. Continue running. Cycling again. Returning to outdoor training after a winter of less activity.
And then your legs remind you that enthusiasm is not the same as fitness.
Post-exercise muscle soreness, the deep ache that comes 24 to 48 hours after exercise, is a normal part of returning to activity. Your body adapts. But how well you recover between workouts has a direct influence on how quickly you progress and how pleasant you experience the process.
Rest is essential. Nutrition counts. Sleep is crucial. But there's a fourth factor that many active people don't know about yet, and it fits easily into one post-workout routine without extra effort or complexity.
How Does Red Light Therapy Support Muscle Recovery?
Red light therapy supports muscle repair at the cellular level through a process called photobiomodulation.
When red light in the range of 630 to 670 nm and near-infrared light in the range of 810 to 850 nm reach muscle tissue, they are absorbed by cytochrome c oxidase, an enzyme in the mitochondria. This absorption increases ATP production, reduces oxidative stress, and modulates the local inflammatory response in ways that can support faster tissue repair.
Hamblin et al. described this mechanism in detail and noted that photobiomodulation influences mitochondrial redox signaling and subsequent cellular responses relevant to repair and inflammation. A second review article by Hamblin further described how these anti-inflammatory effects work at the cellular level.
In practice, the cells involved in the repair of muscle tissue receive more energy to do their work after exercise, and the inflammatory cascade that causes muscle pain is modulated rather than simply suppressed.
Is this the same as LLLT or photobiomodulation?
Yes. Red light therapy, low-intensity laser therapy (LLLT) and photobiomodulation (PBM) all fall under the same category of light-based interventions. The term varies by context, but the mechanism is consistent: focused red and near-infrared wavelengths interact with cellular chromophores to produce biological effects at the tissue level.
Key points
- Red light (630 to 670 nm) and near-infrared light (810 to 850 nm) are absorbed by cytochrome c oxidase in the mitochondria.
- This absorption increases ATP production, reduces oxidative stress and modulates inflammation.
- The effect is not heat related. It is a photochemical reaction at the cellular level.
- Hamblin et al. have published several peer-reviewed overview articles on these mechanisms.
What does the research say about red light therapy and muscle recovery after exercise?
The evidence for photobiomodulation in muscle recovery is among the strongest areas of red light research, particularly for reducing markers of muscle damage and muscle soreness.
A systematic review by Paolillo et al., published in Laser Physics, found that low-intensity laser therapy applied before or after exercise was associated with improvements in muscle strength and reduced markers of muscle damage, including creatine kinase (https://pubmed.ncbi.nlm.nih.gov/21878042/).
Infrared lamp therapy research by Tseng et al., published in the European Journal of Applied Physiology in 2024, found that far-infrared lamp sessions after a simulated football match supported faster recovery of muscle damage markers and performance measures in elite female athletes compared to sham conditions (https://pubmed.ncbi.nlm.nih.gov/38556845/).
A related study by Chen et al., published in the Journal of Strength and Conditioning Research in 2023, found that far-infrared lamp therapy after eccentric exercise reduced muscle soreness and creatine kinase levels and supported faster recovery of strength and proprioception compared to sham conditions (https://pubmed.ncbi.nlm.nih.gov/36825876/).
It is worth noting that most studies use controlled conditions, specific wavelengths, irradiances and timing protocols that cannot be exactly translated to home use. The direction of evidence is positive, but the research is still developing and results will vary from person to person.
Does red light therapy specifically reduce muscle pain?
Current research suggests yes, especially when applied just before or within 1 to 4 hours after exercise. The proposed mechanism is that photobiomodulation reduces the inflammatory markers and oxidative stress that contribute to post-exercise muscle soreness (DOMS), rather than simply masking the feeling.
Key points
- Multiple studies support the use of photobiomodulation to reduce creatine kinase, an important marker of muscle damage after exercise.
- Far infrared lamp therapy has demonstrated recovery benefits in both elite athletes and in controlled laboratory conditions.
- Timing seems to be important. Applications before or shortly after exercise generally show stronger effects in research.
- Results vary by person and home use should be approached with realistic expectations rather than guaranteed outcomes.
When and how do you use red light therapy in spring training?
The most consistent findings in the literature suggest that timing and dose are important. Here is a practical framework based on current evidence.
Timing: before or after training?
Both approaches are backed by research, but for most people recovering from DOMS, applying red or near-infrared light within 1 to 4 hours of exercise is the most practical option. Some athletes use it immediately after the session, while they are still in a recovery state.
Pre-workout application (5 to 10 minutes before exercise) has been studied for performance and fatigue resistance benefits, but post-workout application is more relevant for people whose primary goal is to reduce muscle soreness between workouts.
Wavelength: red or near infrared?
Red light around 660 nm penetrates to a depth of approximately 5 to 10 mm and covers the superficial muscle layers and skin. Near infrared around 850 nm penetrates deeper, up to 20 to 30 mm or more, making it more relevant for larger or deeper muscle groups.
For general leg or back repair after running or cycling, a combination of red and near-infrared wavelengths is often considered more comprehensive. Mvolo's Elite Series panels emit multiple wavelengths, including both red and near-infrared, which is why they are used by people with a variety of recovery goals.
Duration and dose
Session length varies across studies, but 10 to 20 minutes per area is commonly used. The total energy dose counts more than the session duration alone: irradiation strength (measured in mW/cm2) multiplied by time (in seconds) gives you the joules per cm2 delivered to the tissue. For a more detailed explanation of how to calculate the irradiation strength and dose for home use for your specific Mvolo device, see Mvolo's guide on the best irradiation strength for red light therapy.
Frequency
For active training periods, 3 to 5 sessions per week is a common recommendation in the literature. The biphasic dose response described by Huang et al. (Dose Response, 2009) is relevant here: both too little and too much light can reduce the effect, with the optimal response being in a middle range (https://pubmed.ncbi.nlm.nih.gov/19622912/).
Key points
- Post-workout application within 1 to 4 hours is the most practical option for DOMS reduction.
- Red light at 660 nm works on superficial muscle layers. Near infrared at 850 nm reaches deeper tissues.
- A combination of red and near-infrared wavelengths is more comprehensive for muscle recovery.
- 10 to 20 minutes per area, 3 to 5 times per week, is a common protocol in the research literature.

Frequently Asked Questions
Does red light therapy really help with muscle pain? The research suggests yes, especially for reducing markers of muscle damage such as creatine kinase and supporting recovery from muscle soreness after exercise. Studies by Tseng et al. (European Journal of Applied Physiology, 2024) and Chen et al. (Journal of Strength and Conditioning Research, 2023) found significant recovery benefits of far-infrared lamp therapy after exercise compared to sham conditions. Results will vary and this should not be used in place of adequate rest and nutrition.
How does red light therapy help muscles recover? Red and near-infrared light are absorbed by cytochrome c oxidase in the mitochondria, which increases ATP production and reduces oxidative stress. This cellular energy boost can support the recovery processes that muscles undergo after exercise. The mechanism is described in detail by Hamblin et al. (Photonics and Lasers in Medicine, 2017) via https://pubmed.ncbi.nlm.nih.gov/29164625/.
When is the best time to use red light therapy after a workout? Most studies use application before exercise or immediately afterwards. For people aiming to reduce muscle soreness, applying red or near-infrared light within 1 to 4 hours after exercise is a practical and evidence-based approach.
How long should a red light therapy session last for muscle recovery? 10 to 20 minutes per target area is a common session duration in studies. The actual dose delivered depends on both the irradiation strength of the device and the distance to the skin. For guidance on calculating the dose for your specific Mvolo device, see the guide on the best irradiation strength for red light therapy.
Is 660 nm or 850 nm better for muscle recovery? Both wavelengths work at different tissue depths. Red light at 660 nm penetrates approximately 5 to 10 mm deep and is effective for superficial muscles and skin. Near infrared at 850 nm penetrates deeper (20 to 30 mm or more) and is more relevant for larger or deeper muscle groups. A combination of both is considered most comprehensive for overall muscle recovery after exercise. The Mvolo Elite Series panels contain both wavelengths. For more details, see whether 660 nm and 850 nm are worth it.
Can I use red light therapy every day during spring training? Research supports regular use, with many protocols performed 3 to 5 times per week. Daily use is not considered harmful, but the biphasic dose response described by Huang et al. (Dose Response, 2009) suggests that more is not always better (https://pubmed.ncbi.nlm.nih.gov/19622912/). Consistent sessions with an appropriate dose are more effective than very frequent or very long sessions.
Can red light therapy replace rest after exercise? No. Red light therapy is best thought of as a supportive tool within a broader recovery approach that includes adequate sleep, nutrition, hydration and appropriate rest between workouts. It can help the body recover more efficiently during rest, not instead.
