5 Most Effective Near-Infrared Light Therapy Devices for Every Application

various red light therapy devices

You’ve probably heard about red light therapy as a way to treat skin disorders, smooth fine lines, and wrinkles, or regrow hair. But do you know about its longer-wavelength cousin, near-infrared light? This amazing treatment can penetrate through the bone, and absorb much deeper into the body’s tissues with an even wider range of benefits than red light.

Near-infrared (NIR) light therapy has successfully treated chronic joint pain, muscle injury, bone disorders, and even stroke and traumatic brain injury, as well as many other conditions. 

In this article, we’ll discuss what near-infrared light therapy is, as well as its innumerable benefits. We’ll also cover what you need to know about NIR light therapy devices, which will help you make the best wellness choice for your personal needs.

Because near-infrared light therapy is referred to by different names (NIR light therapy and sometimes infrared light therapy), we’ll use these terms interchangeably unless otherwise noted.

What Is Near-Infrared Light Therapy?

NIR light therapy uses powerful light-emitting diode (LED) devices to shine specific wavelengths of light onto bare skin, where it stimulates beneficial biological processes. This is also true of red light therapy, although the two are not the same. These therapies use completely different light waves with different characteristics. 

Despite their differences, the term “red light therapy” is often used to refer to NIR light as well as red light. Collectively, red light therapy refers to wavelengths of electromagnetic radiation that we see as the color red, and which falls into the spectrum of colors that make up natural sunlight (considered “white light.”). 

Red wavelengths, which are visible to us, range from 630 nanometers (nm) to 660nm. NIR wavelengths, which are invisible to the human eye, range from 810nm to 850nm. Infrared (IR) light refers to wavelengths longer than 1,000nm. The human body doesn’t perceive IR waves as light, but rather, as heat.  

Infrared light therapy is often available as infrared saunas. One aspect of IR light that’s important to note is that it heats up the water molecules in the body, whereas red light/NIR light does not have that effect. 

Both have their therapeutic applications; in terms of safety, however, LED devices that emit red light and NIR light are safer than IR saunas, which could cause cellular damage if overused.

Light Delivery: The Right Light Therapy Device Matters

NIR light therapy has two delivery systems: low-powered (“cold”) lasers and LED bulbs. Laser devices are typically used in clinical settings and for research. They deliver somewhat more precise beams of light, which are great for targeting specific areas. However, some studies are now using LED devices with statistically significant results comparable to laser devices.

Handheld consumer-grade low-level laser therapy devices are available, but they have extremely limited applications. For example, if you’re using NIR light therapy to treat osteoarthritis, the small size of the device means you’ll be treating tiny areas of the body one at a time. And since arthritis is rarely confined to a single knuckle, you could sit there all day trying to treat many arthritic body parts with a handheld laser device.

As well, handheld battery-operated NIR and red light therapy devices do not deliver the intensity of light required to achieve therapeutic benefits to the treatment area; batteries become depleted with use, and the devices aren’t powerful enough to deliver the concentrated light needed. You won’t get the light output you need for optimal absorption into the body if you use red light therapy wands, masks, caps, or wraps.

Keep in mind, however, that as a home user, you’ll get the best results with a device that delivers NIR light along with red light.

What to Look for in Near-Infrared Light Therapy Products

When considering the various choices available, remember that you’ll get the best results – and the most mileage – from a high-quality LED red light/NIR light panel with the power to deliver concentrated light energy to your skin. When comparing NIR light therapy devices, here are some important features to look for.

Light Energy Output: Irradiance and Joules

As explained earlier, irradiance refers to power output, or how much energy is absorbed by the skin. It is the #1 consideration when comparing NIR therapy lights.

There are often significant differences in power output between red light therapy devices. It’s important to note that the wattage an LED light consumes does not correlate with its light output. You can have a “hungry” device that eats a lot of power but delivers a fraction of the light output of more efficient panels that consume less energy but deliver higher irradiance – which is the only true measure of light output. 

Irradiance shows how many light photons are available to absorb into your cells to spark a biological reaction. Irradiance and joules (units of energy) must be measured together to get an accurate reading of how much light your body actually receives during a therapy session. 

Another consideration is the distance you are from the device. If a company claims that its red light therapy panel produces 100mW/cm2 but doesn’t specify the distance you must be from the device to achieve this intensity, then it’s impossible to accurately compare the actual light output of this device without side-by-side trials. Today, most companies will list irradiance at 6”.

The Ability to Choose Both Red and NIR Light

Although near-infrared light is part of the red light spectrum, their different wavelengths determine how deeply they are absorbed into the body. Red light treats skin health and surface conditions like psoriasis, eczema, fine lines, and wrinkles, or promotes hair growth.

Red light and NIR light have the same energy-stimulating properties. But because of NIR light’s ability to penetrate deeper into the body, it can spark benefits in bones, joints, muscles, and tissues that red light cannot reach. 

This allows the light to address underlying conditions that could be at the root of chronic disorders such as psoriasis or the aching pain of rheumatoid arthritis.

When choosing between the two, consider the physical depth of the conditions you’re treating, and whether going deeper could address underlying causes.

For example, a skin wound can be treated using red light therapy. But a chronic skin condition like rosacea or an autoimmune disorder like arthritis needs the extra penetration depth of NIR light to reduce systemic inflammation that could be contributing to the disorder.  

If you want to enhance skin health, for example, red light is best. But adding NIR light into the mix provides a variety of secondary benefits such as reducing inflammation that could be accelerating cell death on your facial skin (which makes facial skin look dull and aged). 

For deep muscle wounds in your thighs, to relieve pain from arthritis, or to restore brain function following a traumatic brain injury, you’ll want to use NIR light. However, including red light in these treatment sessions will help your skin and boost overall wellness. 

When in doubt, choose a red light therapy device that gives you the choice between red and NIR light, or offers a combination of both for more comprehensive treatment.

Panel Size

Rather than automatically choosing a larger device with greater light power output, consider your needs. For smaller targeted applications like hand joint pain or for a device you can easily travel with, a small panel is ideal. 

If you want to optimize physical performance by treating large muscle groups, you’ll want a larger panel or even a series of joined panels so that you’re not spending hours treating individual body parts.

Convenience, Value, and Customer Service

Choose a quality product that comes with a door mount, pulley system (and other ways to easily position the panel for optimal use), eye protection, a power adapter, and user manual. These features will help you get the most from your red light therapy panel ... and it's a sign that the company cares.

You will get your money’s worth from any of the high-quality devices offered by experienced and reputable manufacturers.

One last consideration is customer service. Be sure you work with a company that enables you to speak to a human who is there to help you have the best possible experience with your light therapy device and to troubleshoot any problems you might encounter.

Does Near-Infrared or Red Light Therapy Work?

To know whether red/NIR light therapy works, it’s important to understand how the wavelengths affect you, and some of the benefits they are most known for.

Our bodies are highly reactive to sunlight. In the morning, the rising sun stimulates the hypothalamus, which is an area of the brain that plays a crucial role in important functions such as the release of hormones. In the evening, the setting sun signals the body to shut down energy production and prepare for sleep. 

Natural sunlight has been used for therapeutic purposes since ancient times. It is known for boosting the immune system, stimulating the production of vitamin D, and treating a type of depression known as seasonal affective disorder, or SAD. 

As beneficial as sunlight can be, however, it also poses hazards. Too much exposure to the sun’s powerful ultraviolet (UV) radiation can cause skin damage as well as damage to DNA, which can lead to skin cancer. Thus, isolating certain wavelengths that provide health benefits without harmful side effects has been a primary focus of anti-aging researchers.

Years of studying light have enabled scientists to isolate specific wavelengths and determine their benefits and dangers. In recent years, scientists have discovered a broad range of effects that specific wavelengths of visible and invisible light have on the body. 

Blue light, for example, helps our natural sleep and wake cycles and leads to improved energy during the day. Because blue wavelengths block the production of melatonin, a hormone that induces sleepiness, it can interfere with sleep. That’s why using blue light-emitting electronic gadgets at night can lead to sleep disruptions. 

The red wavelength spectrum is particularly known for its energy-stimulating properties at the cellular level. As red wavelengths absorb into the skin, this stimulates activity in the mitochondria, which are energy-producing organelles inside most cells in the human body. 

Mitochondria absorb the light photons and begin producing adenosine triphosphate (ATP), the primary cellular fuel. Healthy, energized cells are thriving cells that can perform their specialized functions and repair and replicate themselves more easily than low-energy cells that are fighting for survival. 

Scientific Studies on NIR Wavelengths

Hundreds of studies suggest that NIR wavelengths have a host of beneficial effects on the human body.

Decreased Chronic Inflammation

Chronic inflammation is now recognized as a major contributor to chronic diseases and skin damage. Even aging is now being called “inflamm-aging” by some scientists who have discovered that inflammation can damage DNA, which leads to faster cell death and poor overall cell health.

Studies have shown that red/NIR therapy can have anti-inflammatory effects similar to those of non-steroidal anti-inflammatory drugs (NSAIDs).

A 2017 study by Michael Hamblin, a world-renowned authority on red light therapy, is a fascinating read that describes how NIR wavelengths can decrease chronic inflammation. 

Chronic inflammation, however, is a sign that the immune system has begun to mistakenly attack healthy tissue. The condition has been linked to autoimmune disorders, as well as heart disease, cancer, hormonal imbalances, and many other chronic conditions. Reducing chronic inflammation while stimulating normal, healthy cell proliferation can ease symptoms, ease pain, and reduce the recurrence of chronic conditions.

Even with such a convincing body of research, NIR light therapy should be considered a treatment, not a cure. Yet studies on the connection between inflammation and disease have clearly shown that reducing chronic inflammation using NIR therapy devices can cause spontaneous healing of symptoms.

Brain Health

NIR light can penetrate the skull, and in the process, directly affect neurons (brain cells). NIR light can improve mitochondrial function and cellular repair of neurons, stimulate neuron growth, offer a neuroprotective effect, improve cerebral blood flow, reduce oxidative stress in the brain, and decrease brain inflammation.

Transcranial NIR therapy has been found to benefit brain health and improve post-traumatic brain injury-related cognitive performance, including improved attention and memory retrieval.

A 2015 joint study by Australian and French researchers found that NIR light therapy has great promise for treating neurodegenerative brain disorders such as Alzheimer’s and Parkinson’s disease, including slowing their progression.

During a 2016 study by the Neuro-Laser Institute, NIR therapy successfully treated traumatic brain injuries. 

In 2007, a study by Israeli researchers confirmed initial safety and effectiveness for the use of infrared lasers in the treatment of ischemic stroke when treatment started within 24 hours of stroke onset.

A 2009 feasibility study on a small group of patients with major depression (including nine with anxiety, seven with a history of substance abuse, and three with post-traumatic stress disorder) suggests that NIR light therapy could be used to treat depression and other psychiatric disorders.  

NIR light was shown in a 2015 study to be an effective complementary therapy for many neurosurgical applications. The study authors also stated that NIR light is effective in wound healing and inflammation on the central and peripheral nervous systems.

Accelerated Healing

NIR light therapy can accelerate healing in various ways, including:

  • Helping damaged cells repair and regenerate more effectively;
  • Increasing cellular energy, which supports cells in healing themselves;
  • Increasing the production of fibroblasts, which are the cells that produce collagen, a protein that’s essential for rebuilding skin and other structures;
  • Increasing microcirculation of both blood and lymph, to supply the wound with more oxygen and nutrients and efficiently remove waste;
  • Decreasing chronic inflammation that can interfere with the healing process.

Multiple studies have demonstrated the benefits of red/NIR light therapy on wound healing. This 2016 review by researchers from Delhi, India suggests that NIR light therapy is a promising drug-free approach for promoting healing, relieving pain, reducing inflammation, and restoring joint function. The review found that NIR light could be a “biophysical therapeutic intervention for chronic non-healing dermal wounds.”

A 2012 study found that 830nm NIR treatment accelerated bone repair in osteoporotic rats, which holds great promise for the 10 million patients in the US who suffer from osteoporosis.

Improved Athletic Performance

NIR light can supercharge the effects of exercise and can help you increase muscle mass, lose excess fat, reduce pain from hard workouts, and make significant gains in performance, endurance, and strength.  

One of the secrets is that muscle tissue contains far more mitochondria than almost any other tissue in the body because muscles require a lot of energy. Therefore, increasing cellular energy by encouraging cells to produce more of the fuel ATP will give the muscles more “oomph” to push through a hard workout; and recover faster. As well, more blood flow to the area will help muscles perform at their best and recover faster.

​Accelerated recovery and healing from injury are key to peak athletic performance, whether you’re an elite athlete or a weekend warrior. NIR light therapy has been shown in numerous studies, including this 2016 review, to maximize athletic performance and reduce muscle recovery time. In fact, the study authors said NIR light treatment could give athletes an unfair advantage in officially sanctioned competitions.

Pain Relief

Another strong finding from the research is that NIR light can be an effective treatment for reducing joint pain – which could be a life-changing treatment for anyone suffering from osteoarthritis, fibromyalgia, sacroiliac joint pain, neuropathic pain, knee pain due to osteoarthritis, tendonitis, and chronic pain disorders. For a detailed review of studies on the effects of NIR on pain, check out this article on pain and one specifically on joint pain.

If you have neuropathic pain, NIR light can help with that as well. And if you suffer from fibromyalgia pain, here’s an article about how NIR light can help with that condition.

Beauty Benefits

As mentioned previously, red light is the star when it comes to treating the effects of aging and other “skin-deep” conditions. These can include chronic skin disorders, reducing wrinkles and fine lines, smoothing out stretch marks, and treating acne (as well as hair growth).

But to truly heal chronic skin conditions you need to go deeper, using NIR light therapy to get to the source – which, in many cases, is inflammation.

Also, check out this article on weight loss, a surprising and often welcome side effect of NIR light therapy. (You’ll get the best results if you combine NIR light therapy with exercise, stress relief, and good nutrition.)
