Red Light Therapy: Benefits, Uses, How It Works, and Risks


Have you ever considered the healing power of Light? In medical advancements, a fascinating therapy—Red Light Therapy (RLT) has been gaining attention. But what exactly is it, and how can it benefit you? Join us to explore the profound advantages, varied uses, the science behind it, and potential risks associated with Red Light Therapy.

The Basics of Red Light Therapy

Red Light Therapy, a form of Photobiomodulation (PBM), uses Red and Near-Infrared Light to stimulate cellular activity. Unlike other forms of Light Therapy, this treatment penetrates deeper into the skin and body, reaching the mitochondria—the powerhouse of our cells.

How It Works

In simple terms, these Red and Near-Infrared wavelengths enhance cellular function by increasing the production of adenosine triphosphate (ATP). This boost in energy facilitates a range of positive effects, from reducing inflammation to promoting tissue repair. 

Unveiling the Benefits

Enhanced Muscle Recovery:

Athletes and fitness enthusiasts rejoice! Red Light Therapy has shown promising results in accelerating muscle recovery post-exercise. By reducing inflammation and promoting cellular regeneration, it aids in minimizing downtime between workouts.

Skin Rejuvenation:

Bid farewell to fine lines and wrinkles! The therapy’s ability to stimulate collagen production makes it a sought-after solution for those looking to rejuvenate their skin. Over time, users often report a more youthful and radiant complexion.

Pain Management:

Chronic pain sufferers may find relief in Red Light Therapy. The anti-inflammatory properties and increased circulation help alleviate pain (associated with arthritis or anything else that causes pain), providing a non-invasive alternative to traditional pain management approaches. Whole-body Red Light Therapy panels enhance endorphin production, which can help with pain management, too. 

Wound Healing:

In the realm of wound care, Red Light Therapy shines—quite literally. The stimulation of cellular repair processes expedites the healing of wounds and cuts. This makes it a valuable addition to traditional wound care practices.

Cognitive Function:

Surprising as it may sound, Red Light Therapy can positively affect cognitive function. Some studies suggest that Red Light Therapy may aid in mitigating cognitive decline associated with aging, though more research is needed in this area.

Mood and Sleep Regulation:

Are you struggling with sleep or mood issues? Preliminary studies indicate that Red Light Therapy might regulate circadian rhythms, potentially improving sleep quality and mood disorders. The endorphin production with whole-body RLT can also help with mood. 

Sexual Function:

Problems with blood flow and circulation can cause sexual dysfunction. Red Light Therapy improves blood flow safely. Enhance your libido, erection strength, and orgasms safely. More research is needed in this area.


Improving the energy of sperm can improve motility. In females, we are born with all our eggs, but adding energy, decreasing oxidative stress, and improving circulation can be beneficial. We need more studies on this topic. 

A Closer Look at Red Light Sessions 

Duration and Frequency:

The optimal duration of a Red Light Therapy session varies depending on the desired outcome. Sessions at Deepy Vital Medical typically range from 20 to 60 minutes, with frequency going from one to several times a week. It depends on what you are treating, and everyone responds differently; it may depend on the length of time you have had the issue, the health of your skin, and the distance between you and the Lights.  

Understanding the Risks 

Red Light Therapy, known as low-level laser therapy (LLLT) or photobiomodulation (PBM), is generally considered safe when used correctly. However, some risks and considerations, like any medical or therapeutic treatment, may exist. It’s important to note that the research on Red Light Therapy is still evolving, and not all potential risks or benefits may be fully understood. It is also important to note that the thousands of studies done in the last few decades all show safety without adverse reactions. Here are some potential considerations:

Photosensitivity Reactions: There is always a risk of adverse reactions in light-sensitive individuals. However, this is rare and has not been seen in any study or anecdotally in our practice at Deeply Vital Medical

Skin Burns: Burns are possible with lasers or cheaper quality machines with ultraviolet Light. Although we do not recommend being under the LED Lights for hours, you can stay under them without getting burned.

Medication Interactions: Some medications may increase sensitivity to Light, potentially posing a risk during Red Light Therapy. However, this has yet to be seen in our practice or any studies to date. 

Pregnancy Concerns: Limited research on the effects of Red Light Therapy during pregnancy warrants caution, though Dr. Weber suspects it is ok to use Red Light wavelengths and turn off the Near-Infrared Light wavelengths to prevent warming and still attain the benefits of the Red Light wavelengths.  

Cancer Considerations: We need more research, but concerns about potential tumor growth promotion, especially for individuals with a history of active cancer, are understandable. There have been conflicting studies, but there are studies showing regression of tumors and a better quality of life after exposure to PBM. The therapy is excellent at treating chemotherapy and radiation-induced symptoms and can help improve tolerance to treatments. 


Red Light Therapy is a beacon of hope in non-invasive medical treatments. Its versatility and growing research suggest that this therapy could revolutionize how we approach various health and wellness concerns. However, as with any medical intervention, it’s essential to consult with healthcare professionals to ensure a tailored approach that aligns with individual health needs.

In pursuing optimal health, the glow of red Light and the warmth of near-infrared Light may illuminate a path to a brighter, healthier future. So, are you ready to get into Red Light Therapy? The potential benefits await, offering a spectrum of possibilities for enhanced well-being.
