red light therapy covid

Wondering how you can prevent yourself from contracting COVID-19?  There are plenty of things that you can do to strengthen your body’s defenses against all viruses, pathogens, microbes and all known diseases.  Things like vaccines are cheap alternatives and vastly inferior to many of the natural approaches currently available.

Red light therapy in particular has been well studied for COVID and has powerful anti-inflammatory and immune boosting properties that can enhance your body’s metabolism, and improve the function of every single cell, organ and system simultaneously and without side effects.  If you’ve already got COVID, then listen up, because red light therapy could cut your recovery time in half.

In this article, you’re going to see some of the powerful evidence that has accumulated, since the pandemic was declared in March 2020, showing that light therapy - and particularly red and near-infrared laser and LEDs - have proven safe and effective in facilitating rapid healing of severe COVID-19 patients.


Understanding COVID-19 Physiologically

It’s important to not get caught up in the fear pushed by governments and the media surrounding COVID-19.  The way to transcend that fear is by understanding physiologically how the disease affects the body.  A study from January 2021 showed that COVID is simply another case of widespread mitochondrial dysfunction, no different than virtually all other diseases in existence, including diabetes, cancer, heart disease, obesity, Alzheimer’s, etc.

“We demonstrate mitochondrial dysfunction, metabolic alterations with an increase in glycolysis… from patients with COVID-19… These data suggest that patients with COVID-19 have a compromised mitochondrial function and an energy deficit that is compensated by a metabolic switch to glycolysis. This metabolic manipulation by SARS-CoV-2 triggers an enhanced inflammatory response that contributes to the severity of symptoms in COVID-19,” wrote scientists.[1]

And as such, this condition is easy to prevent and correct.  The best medicines for the job are well known, inexpensive, safe and easy to obtain.


Typical Symptoms of COVID-19

The hallmark of a severe case of COVID-19 is pneumonia.  According to a study in the journal Nature, the main pathology of it includes “intense damage to the air sacs of the lungs” caused by inflammation.  Some scientists theorized that the inflammation caused by COVID-19 was somehow different than the inflammation that arose from other causes, but that theory turned out to be untrue.[2]

The inflammation seen in COVID-19 patients is the exact same as any other inflammation, which in the case of COVID-19 is caused by collateral damage from the immune response to the virus.  Since red light is one of the most powerful anti-inflammatory factors known, a powerful immune booster, and non-specific tissue-healing accelerant, we should expect great things from this powerhouse treatment on severe COVID-19 patients.  Let’s look at some of the data that scientists have churned out since the pandemic’s inception.

Red light therapy: A Powerful Anti-inflammatory & Lung Healer

In 2021, Iranian scientists conducted a review to find out whether or not red light could treat COVID-19 lung inflammation and also to find out if it could heal the damaged air sacs caused by it.[3]

Included in the review were 17 scientific papers and the study concluded that red light therapy “could significantly decrease the pulmonary edema, neutrophil influx, and generation of pro-inflammatory cytokines.”  In other words, when used in COVID-19 patients, red light therapy can…

  • Reduce the fluid and swelling in the lungs that make it difficult for patients to breathe (dyspnea)
  • Reduce inflammation by quelling the production of pro-inflammatory signaling molecules
  • Accelerate healing of damaged air sacs caused by inflammation

“Our findings revealed that the PBM could be helpful in reducing the lung inflammation and promoting the regeneration of the damaged tissue,” they wrote, and recommended the use of either lasers or LEDs for treatment.

Case Studies of Red Light Therapy Healing COVID Patients

Dr. Scott Sigman has done some notable work in 2020 treating COVID patients using the Multiwave Locked System (MLS) laser.  Working at the independent, not-for-profit Lowell General Hospital in Massachusetts, there have been two documented case studies of COVID patients who’ve gotten well after treatment by Dr. Sigman using the red light therapy laser – one in August, 2020 and the other in September, 2020.  Let’s go over both of them now.

A 57-year-old African American Man Healed COVID Using Red Light Therapy

A 57-year-old African American man diagnosed with COVID-19 was admitted to the ICU for respiratory distress in August 2020 and in need of oxygenation.  For treatment he was administered the MLS laser once-daily for 28 minutes each session for four days and a total of four treatments.

"He was discharged to a rehab facility one day after his last treatment. Prior to that, he was not able to walk, he had very bad cough, difficulty breathing," Dr Scott Sigman said.  And just one day after being at the rehab facility, he was able to complete two trials of stair climbing during physical therapy.  The typical recovery time for patients in his condition is about six to eight weeks, and this particular patient was fully recovered in three weeks.[4]

A 32-year-old Asian Female Healed COVID-19 Using Light Therapy

The second case study by Dr Sigman was on a morbidly obese 32-year-old Asian female with severe COVID-19 and published one month later in September 2020.  After being admitted to the ICU, this patient received a total of four treatments over the course of four days, directly to the chest for 28 minutes per session.  “Appreciable improvement in respiratory symptoms” was noted following her treatments and x-rays were taken to assess the condition of her lungs.

The Radiographic Assessment of Lung Edema (RALE) Scores by Chest-X-Ray confirmed the improvement of the lungs after Laser Therapy for the patient.  "Not only did the chest X-ray dramatically clear, but important markers of inflammation, IL-6 and Ferratin, decreased after four days of treatment.” said Dr. Sigman.[5]

LED Light Therapy Devices Superior to MLS Laser

We know that light therapy using the MLS laser can rapidly accelerate healing in severe COVID-19 patients in just 4 daily treatments.  However, the MLS laser comes with a very high price tag.  Let's compare the MLS laser to LED light therapy devices from


The MLS Laser emits two different wavelengths of near-infrared laser light.  The first beam emits 808nm and the second beam emits 905nm pulsed.  The EAD Bodylight mini and full bodylight emit 4 wavelengths of light (2 red and 2 near-infrared) which are scientifically proven to be the most efficiently absorbed by cells: 620, 670, 760 and 830nm.  Both lights will penetrate deep into the tissues of the body and be absorbed by enzymes within cells, but the light from the EAD devices will be absorbed more efficiently, giving them the advantage over the MLS laser.


The peak power of the MLS laser is 75 Watts, whereas the EAD Bodylight mini is 180 Watts and the EAD Full bodylight boasts a robust 600 Watts of power.  Even the compact EAD bodylight mini provides more power than the MLS laser, and the EAD full bodylight eclipses its power by 800% at a small fraction of the cost!


The cost of an MLS laser itself is an astronomically high, at $30,000 or more, depending on who’s selling it.   Compare that to the EAD Full Bodylight, which costs only $699, and the price difference is enormous.  To put it into perspective, the EAD Full Bodylight is 8x more powerful than the MLS laser, and yet the price is 43x less!

Cost Per Treatment

Cost of MLS laser therapy treatment depends on where you go to receive the treatment, but it generally ranges from about $40 to $80 per treatment.  Commonly sold are bundled treatment packages, for example a 12 treatment package for around $540.  When you consider the fact that EAD Red & Near Infrared light therapy devices last 50,000+ hours, which is many years of non-stop use, the cost per treatment can be as low as $0.10 per session.

If the 75 Watt MLS laser can reduce healing time of severe COVID-19 patients from 8 weeks down to just 3, then just imagine what the 8x more powerful Endalldisease Full Bodylight can do!


Since the COVID-19 pandemic was declared in March 2020, scientists from many countries across the world have been exploring various treatment methods for victims of the disease.  Without a doubt, one of the best ways they’ve found has been red and near-infrared light therapy.

Red light therapy has been found to accelerate the healing of damaged air sacs of the lungs that the disease so typically causes in its advanced stages, and it also eliminates the dyspnea or difficulty breathing that many people with the disease face.

Use of a near-infrared laser in a clinical setting has proven that in just four treatments of less than 30 minutes each session, patients can be back on their feet and doing multiple sessions of stair climbing within just a couple days.

Since publishing my bestselling book Red Light Therapy: Miracle Medicine, the technology and testimonials coming in never cease to amaze me, and the use of red and near-infrared light therapy against COVID is certainly no exception and has never been more appropriate.  Red light therapy is here to stay.

  1. Mitochondrial metabolic manipulation by SARS-CoV-2 in peripheral blood mononuclear cells of patients with COVID-19
    The COVID-19 pandemic has been the primary global health issue since its outbreak in December 2019. Patients with metabolic syndrome suffer from severe complications and a higher mortality rate due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We recently proposed that SARS-CoV-2 can hijack host mitochondrial function and manipulate metabolic pathways for their own advantage. The aim of the current study was to investigate functional mitochondrial changes in live peripheral blood mononuclear cells (PBMCs) from patients with COVID-19 and to decipher the pathways of substrate utilization in these cells and corresponding changes in the inflammatory pathways. We demonstrate mitochondrial dysfunction, metabolic alterations with an increase in glycolysis, and high levels of mitokine in PBMCs from patients with COVID-19. Interestingly, we found that levels of fibroblast growth factor 21 mitokine correlate with COVID-19 disease severity and mortality. These data suggest that patients with COVID-19 have a compromised mitochondrial function and an energy deficit that is compensated by a metabolic switch to glycolysis. This metabolic manipulation by SARS-CoV-2 triggers an enhanced inflammatory response that contributes to the severity of symptoms in COVID-19. Targeting mitochondrial metabolic pathway(s) can help define novel strategies for COVID-19.

    3. Probable positive effects of the photobiomodulation as an adjunctive treatment in COVID-19: A systematic review
    COVID-19, as a newly-emerged viral infection has now spread all over the world after originating in Wuhan, China. Pneumonia is the hallmark of the disease, with dyspnea in half of the patients and acute respiratory distress syndrome (ARDS) in up to one -third of the cases. Pulmonary edema, neutrophilic infiltration, and inflammatory cytokine release are the pathologic signs of this disease. The anti-inflammatory effect of the photobiomodulation (PBM) has been confirmed in many previous studies. Therefore, this review study was conducted to evaluate the direct effect of PBM on the acute lung inflammation or ARDS and also accelerating the regeneration of the damaged tissues. The indirect effects of PBM on modulation of the immune system, increasing the blood flow and oxygenation in other tissues were also considered.
    Results: Seventeen related papers were included in this review. All of them were in animal models. They showed that the PBM could significantly decrease the pulmonary edema, neutrophil influx, and generation of pro-inflammatory cytokines (tumor necrosis factor-α (TNF-α), interleukin 1 beta (IL-1β), interleukin 6 (IL-6), intracellular adhesion molecule (ICAM), reactive oxygen species (ROS), isoform of nitric oxide synthase (iNOS), and macrophage inflammatory protein 2 (MIP-2)).
    Conclusion: Our findings revealed that the PBM could be helpful in reducing the lung inflammation and promoting the regeneration of the damaged tissue. PBM can increase the oxygenation indirectly in order to rehabilitate the affected organs. Thus, the infra-red lasers or light-emitting diodes (LEDs) are recommended in this regard.
