Adding cash flow to your business with Red Light Therapy
You’ve undoubtedly heard about red and near-infrared light therapy as a way to treat sore muscles and osteoarthritis joint pain, and even to enhance bone health.
If you’re wondering whether it’s worth adding near-infrared (NIR) light to your treatments, here’s how you can use it along with physical therapy to support and even enhance the effects of other therapies in your wellness center.
What You Need to Know About Near-Infrared Light for Physical Therapy
Red light therapy is a term that encompasses both visible red and invisible near-infrared (NIR) wavelengths of electromagnetic radiation.
It’s important to understand the differences between various types of electromagnetic radiation so you can give your clients the best physical therapy results.
Near-Infrared vs. Infrared: What’s the Difference for PT?
The term “radiation” can be scary, but all light (and all heat) is a form of electromagnetic radiation. Some of this radiation is perceived by the human eye as light; some is perceived as heat.
Wavelengths over 780 nanometers (nm) are considered infrared (IR).
NIR wavelengths (780 to 1000 nm but most commonly 810-850 nm) are used in red light therapy devices.
These wavelengths absorb just below the skin, where they stimulate cellular energy and health by increasing mitochondrial production of more adenosine triphosphate (ATP), which is the primary fuel of the body’s cells.
This benefits the cell directly, and on a bigger scale, the system to which the cell belongs. NIR wavelengths also increase blood flow, stimulate collagen synthesis, and reduce inflammation to promote accelerated wound healing and muscle recovery.
Mid-infrared (MIR) wavelengths, which range from 1000 nm to 3000 nm, penetrate deeper into the body’s tissues where they raise body temperature. As they heat the body, the body works to cool itself by increasing heart rate, cardiac output, and metabolism, which supports weight loss and healing. hat feature MIR wavelengths are used for overall health.
Does it matter whether a wavelength is perceived as light or as heat? Yes.
All wavelengths have specific effects on human cells. Some effects are beneficial and some are harmful. For example:
- UV light improves chronic skin conditions, yet overexposure damages skin cells and is known to cause skin cancer.
- RLT stimulates mitochondrial energy production as well as collagen synthesis. According to a huge body of scientific studies, red and NIR waves do not cause damage to cells, while helping psoriasis, rosacea, age spots, and other signs of aging.
- MIR wavelengths activate heat shock proteins to stimulate cellular self-repair and regeneration; however, overexposure can damage heat-sensitive organs.
Red light therapy devices typically emit red and NIR wavelengths between 620nm and 850nm. The treatment within this range is considered light therapy and not heat therapy, even though there is a very mild heating effect with NIR waves.
How to Use Red Light Therapy In Your Wellness Clinic
Near-infrared light physical therapy is making huge strides in the physical therapy community both as a complementary and primary treatment. The benefits of red light therapy are numerous. Here are some ways that this natural, safe, non-invasive, and pleasurable treatment can help your clients achieve the results they want.
Management of Acute and Chronic Pain
Near-infrared light therapy has been consistently shown in clinical trials to be effective for treating sports injuries, overuse injuries, osteoarthritis, chronic low back pain, neuropathic pain, and even broken bones.
How can shining light on a painful area offer relief?
NIR therapy bridges the beneficial effects of light therapy and heat therapy:
- Like red light, NIR light stimulates cellular functioning and cellulite, boosts collagen synthesis, promotes blood and lymph flow, and reduces inflammation.
- Unlike red light, NIR light generates a small amount of heat in the body by exciting water molecules in the cells. Heat has been shown to have pain-relieving effects and to increase connective tissue elasticity, which is likely (at least partially) due to increased blood flow and a temporary mild inflammatory reaction.
It’s important to repeat NIR light generates very little heat. NIR light has been used successfully to treat conditions in heat-sensitive body parts, including the eyes and testicles. Light therapy helps relieve muscle and joint pain and has been proven safe and effective.
What does the research say?
A 2012 study by Chinese researchers observed the effects of NIR light on chronic pain, when used with nerve block (NB) or local block (LB).
This three-week study evaluated the intensity of pre- and post-therapy pain in 52 patients with shoulder periarthritis (frozen shoulder), myofascial pain syndrome, or lateral epicondylitis.
The patients were randomly assigned to two groups: Group I received NB or LB along with near-infrared light. Group 2 received the same nerve or local block, but did not receive NIR light treatment.
Immediately after treatment, the researchers observed a significant difference between the test and control groups, with no side effects.
They concluded that NIR light therapy effectively and safely treated chronic pain and that it has synergic effects with NB and LB.
The researchers also determined that the effects of the treatment are short-lived, which suggests that ongoing treatment could be beneficial in treating chronic pain.
Rehabilitation After Injury
Near-infrared light therapy has been shown to accelerate healing of muscles, connective tissues, bones, the brain, and even nerve damage following injury.
Photobiomodulation also effectively supports wound healing for chronic wounds that won’t heal.
21 healthy men and 18 women were observed after receiving active and sham red light treatments on the biceps muscle on two separate, randomized days.
After treatment in a 2015 study, participants were asked to complete bicep exercises.
Participants receiving the NIR treatment experienced less strength loss before and after workouts due to muscle fatigue than participants receiving the sham treatment.
This study suggests that NIR light therapy can act as an ergogenic aid by improving skeletal muscle function.
Improving Osteoarthritis Joint Pain
Cartilage degradation is one of the main causes of joint pain. Scientists have long believed that cartilage regrowth is impossible, but there is some evidence to the contrary.
A 2017 study by researchers from Mecca, Saudi Arabia found that light therapy in conjunction with glucosamine/chondroitin supplements resulted in the growth of synovial cartilage within the joint capsule.
Another study that had similar findings was conducted in 2019 by researchers from Brazil. They found that treating rats with 850 nm NIR light resulted in increased cartilage density.
NIR light has also been shown effective in improving range of motion and flexibility, and helping prevent morning stiffness among arthritis patients.
How Effective Is Near-Infrared Light Therapy?
The big question, of course, is whether natural, non-invasive treatment with NIR light lives up to its potential in real life.
Based on numerous studies, near-infrared light therapy is highly effective; at the very least in a supporting role, and potentially in a leading role in physical rehabilitation and pain management.
Take chronic low back pain for example.
Low back pain affects most adults at one time or another. Those who develop chronic back pain are often willing to try anything to get some relief – and NIR light therapy is one such treatment. Here’s a brief look at how NIR therapy works to ease back pain, especially with regular use.
According to a 2015 study on pain from temporomandibular disorder (TMD), near-infrared light therapy has mild analgesic effects. This may be at least partially due to the slight thermal effect of NIR wavelengths.
But more than just temporarily relieving pain, NIR light helps address the root cause of chronic low back pain and supports the body’s natural healing mechanisms. Benefits include:
- Increased cellular energy, leading to enhanced cellular performance;
- Reduced chronic inflammation that could be contributing to pain;
- Activation of stem cells to speed up healing;
- Increased collagen production to help repair damaged muscle and connective tissue;
- Increased blood circulation and lymph flow.
For pain relief and restoration of mobility, it’s important to use NIR wavelengths. Red wavelengths can absorb about 3mm into the skin, whereas the depth of NIR wavelengths is about 10mm; thus, NIR light penetrates not only the skin but also underlying tissue, and even dense connective tissue and bone.
And NIR light carries no danger of the thermal damage that could come from extended exposure to longer mid-infrared wavelengths.
Light Therapy - Stimulating Healing and Improving Bone Health:
The body is naturally designed and made to be able to build newer bones when the need arises.
Studies on animals and humans have shown that red and infrared light therapy greatly aids in healing breaks, fractures, and bone defects. In 2013, researchers in Sao Paulo, Brazil, studied the effects of red and near-infrared light on rat bones' bones' healing process.
Upon a piece of bone being sliced from the upper leg in an “osteotomy” of 45 rats, the rats were split into three groups — Group 1 Received no light, the second group were administered red light (about 660–690 nm), and the third group was placed on exposure to near-infrared light (about 790- 830nm)
The study found “a significant increase in the degree of gray level (mineralization) in groups treated with the laser after 7 days” and “after 14 days, only the group treated with the laser therapy (red light and near-infrared light) in the infrared spectrum showed higher bone density.
Red light and near-infrared light have been shown to stimulate energy production in the bone cells, improve blood vessel formation, circulation, and blood flow to the affected area, regulate and decrease inflammation, increase bone growth factors, enhance the production of collagen and procollagen, which stimulates the growth of bone cells.
Because ATP production is interrupted in broken bones, and cells begin to die due to a lack of energy, the right kind of red light and near-infrared light therapy has shown increased bone formation and collagen deposition. It’s no wonder red light, and NIR is gaining so much momentum in sports teams among athletes.
Many pro teams now use light therapy to speed recovery and get their players back in action after an injury, more every year. Red and near-infrared light wavelengths can penetrate deep into tissue and bone for all kinds of healing effects. Concentrated natural light stimulates the mitochondria in the cells, reducing oxidative stress and helping the body to produce more usable energy to power itself, regenerate, and heal.
Bone Density Benefits
- Increases bone mineral density and bone structure: Preliminary research shows benefits for improving osteoporosis, including a boost in osteogenesis, increased stress load, and preserved vertebrae strength
- Strengthens bones: Increases osteoblast proliferation, collagen deposition, and 3 bone neoformation when compared to bones not treated with red light, and increases maximum bone tolerance
- Improves bone healing: Accelerates bone healing in extraction sites, bone fracture defects and distraction osteogenesis 5
- Reduces swelling from bone injuries: A proven anti-inflammatory treatment indicated by the FDA that has been shown to curb swelling in facial bone fractures
- Enhances overall bone health: Increases natural collagen production, which is essential to healthy bones and skin7

Red Light Therapy Is a Safe, FDA-Cleared Treatment
Many people ask if red light therapy, and specifically NIR light, is safe and if there are any side effects or contraindications.
When used as directed, red/NIR light therapy is safe. Some people may experience temporary tightness and redness of the skin, which is most likely due to increased blood flow to the area. Near-infrared light therapy is based on numerous studies.
That means the benefits outweigh the risks when used as intended. Red light therapy, as mentioned, has no known side effects. The scientific community considers it a safe modality for treating a wide variety of physical conditions including:
Tennis elbow, carpal tunnel syndrome, hip pain, neck pain, and shoulder pain are a few other uses for NIR light.
Meanwhile, there may be other sympathetic benefits, including anti-aging and skin care treatment.
Give Your Clients Results with a Medical Grade Light Therapy Device
To achieve the desired results with your clients, it’s important to use a powerful medical-grade LED Panel like our over the bed 785w panel
https://juvawave.com/products/juvawave-tl-255-pro-900w-red-light-therapy-pain-relief-weight-loss-skincare-panel?_pos=1&_psq=78&_ss=e&_v=1.0– and you don’t have to seek out laser devices.
Many studies used lasers to deliver red and NIR light to the skin. Yet light-emitting diode (LED) devices are proving to be not only just as effective, but less expensive, safer, and more convenient.
Not just any LED device will do, however, because they’re not all suitable for professional use. Hand-held devices, masks, and pads can work to some extent, but not as effectively or efficiently as medical-grade devices.
A medical-grade device differs from a consumer-grade device in the following ways:
- Clinically proven beneficial wavelengths. These should fall within the “therapeutic window” of effective red (630–660 nm) and NIR (810–850 nm) wavelengths. The best devices use a synergistic combination of red/NIR light simultaneously.
- High light power output, known as irradiance. A larger device will have more power to deliver. Look for the highest light energy output when comparing devices. This is measured in milliwatts per square centimeter, or mW/cm² at 6” from the device. The higher the number, the more potent the treatment. Note the irradiance of Juvawave Panels which have higher light energy output numbers at suboptimal distances than some panels show at 6”. The Juvawave 1800w 360 Panel has an irradiance of 255mw/cm2
- The device is manufactured in an FDA-approved facility.
The presentation of a medical-grade light therapy device in your clinic could be a key selling point for clients, especially given the staggering amount of consumer-grade red light therapy devices on the market.
Important Features that Enhance Treatment Outcomes
Purchasing a medical-grade light therapy device is the first step toward achieving exceptional results for your clients. However, there are a few additional considerations that will make the experience more pleasurable for them – and amplify the effects of the treatment.
- Choose a large modular panel that can be mounted to a horizontal or vertical stand. Light therapy devices that can’t be mounted on a stand may limit the patient to standing for the duration of the treatment (10 to 20 minutes), which is not always feasible and rarely comfortable if one is in pain. Horizontal stands allow the patient to lie comfortably on a massage or exam table while receiving treatment.
- Choose devices that can be linked to one, two, or three additional panels to increase the treatment area. Juvawave panels are designed to be linked together to allow for deep total body coverage at maximum power.
- For the most effective deep tissue absorption, position the panel(s) within 6” to 8” of the targeted treatment area, which concentrates the light energy.
- Ten to 20 minutes is the recommended exposure time during a single session; anything over 20 minutes appears to have diminishing returns. What is more important than the length of the treatment is consistency since the treatment works at a cellular level. The best results come from daily treatment for acute conditions and three to five times per week for chronic conditions.
- NIR light therapy is not a quick fix – it works at the cellular level. While it does offer some immediate relief, the real benefit comes from consistency. It takes time to produce collagen, regrow tissue, allow cells to heal from chronic inflammation, and so forth. Set the expectation with your clients that NIR is a long-term approach, not a band-aid.
NIR Light Therapy for Your Wellness Clinic
There are relatively few coats associated with bringing a quality red light therapy device into your clinic.
These include the cost of the panel and a stand.
Potentially, you may consider purchasing up to four modular panels like our 300 series
https://juvawave.com/products/juvawave-300w-panel-with-hanging-hardware?_pos=1&_psq=300&_ss=e&_v=1.0 that can be mounted on a horizontal and/or vertical stand.
The treatment can be applied to clothed or bare skin, to the targeted area for 10 to 20 minutes of treatment.
You can expect a very quick return on your investment. Offering red/NIR physical therapy can enhance results and increase patient satisfaction.
Many physical therapists charge $50 to $150 per treatment session, and most conditions will require at least one month of treatment to see profound results.
