Since NASA first started testing red light therapy’s potential in the early 1990s, research teams and doctors around the world have discovered more and more possibilities for treating people with natural light. Thousands of studies and trials have been performed on the effectiveness of light therapy, and many more are currently underway.

Clinical research has shown how simple, natural light treatments can have major, positive impacts on your health and fitness. To illustrate the power and possibilities of light therapy, let’s take a look at eight of the most well-documented health benefits of natural light treatments, as shown by peer-reviewed clinical research.

1. Quality Sleep with Light Therapy

Research shows that light therapy actually helps people to get more and better sleep, and also helps them produce more of their own natural melatonin.

Sleep studies over the last decade have shown that people treated with red and near infrared light have better sleep outcomes – even people with debilitating disorders.

In one 2018 study, researchers determined that people with serious migraines were able to both reduce the pain and intensity of their headaches with light therapy. Red light therapy was found to be the only treatment tested that helped patients with their sleeping problems as well as their headache symptoms.

2. Light Therapy for Skeletal System Strength

Light therapy is commonly used for benefits like skin and muscle recovery, but research shows that near-infrared light can penetrate deep into tissues and bone, with well-documented healing and pain effects.

One big reason for this benefit is collagen production. Collagen is one of the most plentiful proteins in the body, forming a key ingredient in skin, muscle and bone alike.

In study after study, researchers have found higher natural collagen levels in patients treated with red light, and especially with near infrared-light which achieves deep tissue penetration. In fact, the results are better than those seen by scientists studying the use of collagen supplements alone to improve bone, muscle, and skin strength and healing.

3. Light Therapy for Reducing Inflammation

Reducing inflammation is one major benefit of red light therapy. Natural light treatments increase blood flow to damaged tissues, and encourage healing and recovery.

One benefit of light therapy has found a home in science is the treatment of muscle pain and inflammation following workouts. Natural light treats muscle soreness and exercise-related inflammation and pain with strong results after even the most demanding training sessions. In other words, even a single light therapy treatment before a physically demanding event can have a major impact on soreness and pain levels days later.

4. Light Therapy for Joint Pain Relief

Over 50 million Americans struggle with forms of arthritis, and millions more have to deal with painful joints from other causes.

Fibromyalgia is a condition in which overactive nerves create extreme sensitivity and constant pain throughout the body for no clear reason. This condition has so far proven difficult for doctors to treat, since it does not stem from a specific injury or infections process. Instead, it seems to lie in how the brain and nerves across the body process daily sensations. In many cases, fibromyalgia cannot be resolved with pharmaceutical options.

According to many suffers, after beginning a regimen of redlight therapy joint pain completely disappears. Another group that largely benefits from red light therapy can found in people suffering from rheumatoid arthritis.

Red light therapy has been found to reduce morning stiffness in trial participants, while improving hand flexibility. It has been used to reduce joint pain in knees and spines, in addition to wrists.

5. Improved Training and Performance with Light Therapy

In the last few years, full-body red light therapy systems have started popping up in the locker rooms and training facilities of professional sports teams and athletes.  Clinical research conducted on athletes over the past decade has found that exercise and training plus light therapy is more effective than just exercise and training. Even short, irregular light therapy treatments results in increased speed, strength, endurance and muscle growth in both pro athletes and regular people with average fitness. Regular, consistent light therapy shows even better results.

Dr. Troy Van Biezen is one of the leading trainers of the PGA. Dr. Van Biezen says just about everyone on the PGA is now using light therapy to help them manage a life on the road and playing tournaments in different cities every week. Even beyond boosting muscle performance, red light therapy makes sleep and chronic pain easier to control.

6. Healthy, Rejuvenated Skin with Red Light

The study of red light therapy as a skin treatment began in the hospital setting, with doctors seeking ways to improve outcomes in cases of serious skin injury.

People with wounds, burns, scars and surgical incisions showed faster and better healing outcomes, with less pain and inflammation along the way when treated with red light This has even been true for people with serious second- and third-degree burns. Today, scientists think this effect may be due to the energy-boosting and growth-promoting properties of red light for the skin it touches.

The cosmetically minded might also recognize that collagen is the protein found in young, glowing skin. Declining collagen production with age is a major reason for the appearance of wrinkles and sagging skin.

Numerous trials have shown that light therapy treatments improve collagen density in skin, resulting in a big improvement in complexion. The natural anti-inflammatory effect of light therapy also plays a big role in decreasing inflammation-related redness, blemishes and skin conditions.

Shani Darden, premier Hollywood skincare professions, says, “red light therapy is one of the best tools for naturally improving skin tone & texture and reducing fine lines & wrinkles.”

7. Improving Brain Health & Cognitive Function

Researchers have found that near-infrared light, including red light wavelengths, can penetrate deeper than even natural light. When administered correctly these can reach bones, joints and even the tissue of the brain.

When near-infrared light is applied directly to the head, wavelengths are able to pass through the skull and reach the brain to stimulate, preserve and regenerate cells & tissues.

Researchers found that people treated with red light therapy had significantly improved reaction times, better memory and more sustained positive emotional states.

Red light therapy has been found to improve executive function – our ability to use higher brain functions such as attention, choice and conscious control of behavior. The results of a 2017 study have very promising results, showing red light therapy may have the exciting potential for treating or preventing memory loss from neuropsychological disorders or normal aging. One of the most promising possibilities is the treatment of Alzheimer’s disease and dementia.

Even patients with traumatic brain injury (TBI) have responded positively to light therapy, showing improvements in mood and sleep. Scans have shown that light therapy helps regenerate damaged brain tissues and can play a big role in neurogenisis – the creation of new brain cells and tissues.

8. Hormone Regulation with Red Light

Like inflammation and joint pain, tens of millions of Americans struggle with their thyroid and other hormone levels. These hormone imbalances can be influenced by artificial light, and can have a huge range of health consequences.

A 3-year study conducted by Brazilian researchers of people with chronic hypthyroidism and thyroiditis who take levothyroxine found improvements for those using light therapy to regulate hormone health. Researchers found people with a history of taking levothyroxine were able to significantly reduce their doses after adding red light therapy to their routines. In nearly half of the cases patients were able to entirely stop taking the medication after extended red light therapy.

More Surface Area = More Benefits

Coverage is key for light therapy because the magnitude of its overall health benefits depends on the percentage of your body’s surface area that gets to enjoy the benefit of red light absorption. Smaller devices are unlikely to be able to mimic the effect of a large, whole-body device.

When using a device that’s large enough to cover your whole body, millions of cells can take in natural light at once and start producing energy for your body. Uniform coverage is key for optimal results, and a small device that covers only a portion of your body will not provide you with the best health benefits. So if you want optimal treatments, look for a bigger device (like the one available in Spa 247).

Light therapy – also known as “photobiomodulaiton” or “red-light therapy” – is a powerful, non-invasive treatment that can improve your cells’ abilities to produce energy and heal. In light therapy, a device delivers concentrated wavelengths of light to the skin and underlying tissues.

Red-Light Therapy has become a popular treatment in recent years due to evidence that it enhances the health of skin, muscles, joints, the skeletal system, improves sleep quality and even fights pain & inflammation.

Light isn’t usually included in the story when we are taught about the benefits of nutrition, exercise or overall healthy lifestyle. Conventional wisdom doesn’t say anything about the effects of the light our bodies receive on our health.

Modern Life Has a Light Problem

Most people don’t realize it, but America has a light problem. In our modern world, many people are now exposed to more artificial light that natural light. It’s so extreme that surveys are finding the average American spends over 90% of their time indoors.

This is a serious health risk. When inventing artificial light, our ancestors didn’t stop to wonder if these artificial light sources would have the healthiest wavelengths our bodies need, or if some wavelengths of light might actually be bad for us. But we now know that our bodies need natural light every day, just like we need water and food.

Scientists took natural light for granted. They assumed it was not important to our health, and attributed health problems that arose with the movement of modern life indoors solely to other factors such as diet and physical activity.

A chronic deficiency of natural light can have a profoundly negative impact on the body, especially on our sleep, mental health, and energy levels. To make matters worse, it’s not just that people don’t get enough natural light; it’s that they’re also getting way too much artificial blue light.

Our cell phones, tablets, television and computer screens are extremely bright, and contain substantially more blue light than daytime sun. They can be difficult to escape these days, and too much blue light, especially after dark, is a primary reason so many people struggle with sleep. This artificial blue light from screens and bulbs effectively “tells” our cells it’s a bright daytime afternoon, even long after the Sun has set.

For countless generations, human biology developed around an abundance of natural light. Our routines and technology have radically changed in the last fifty years, but our biology has not. Humans, like all animals, still need natural light to be healthy and make energy.

Natural light is necessary every day to sleep well, heal and stay in shape. We’ll explore the clinical evidence for this need – and how we can use our cells’ light-based mechanisms to bio-hack our healing and our lifestyles in our next article. Stay tuned… *
