Red Light Therapy
How Does Red Light Therapy Work?
Red Light Therapy is a science-backed, non-invasive treatment that harnesses the power of specific wavelengths of light to activate your body’s natural healing and repair processes.
It’s widely used by wellness professionals, dermatologists, and physical therapists to support skin rejuvenation, pain relief, faster recovery, and overall vitality.
​
What makes Red Light Therapy so unique?
Red Light Therapy doesn’t just work on the surface—it penetrates deep into your cells to stimulate energy production, improve circulation, and reduce inflammation at a foundational level.
This therapy includes both red and near-infrared light, each working at different depths:
-
Red light (visible light, 630-700nm) primarily targets the skin, helping to boost collagen, reduce wrinkles, and accelerate wound healing.
-
Near-infrared light (invisible light, 700-1200nm) penetrates deeper into muscles, joints, and tissues, enhancing circulation, easing pain, and improving cellular function.
​
Why does this matter?
Because our bodies are powered by light, and when used correctly, Red Light Therapy energizes your cells, helping them function more efficiently, heal faster, and reduce oxidative stress.
​
Light is Energy – And Why the Size of the Wavelength Matters
Light isn’t just something we see—it’s energy.
The amount of energy a light wave carries depends on its wavelength, which is measured in nanometers (nm). The size of the wavelength determines how deeply light can penetrate the body, influencing how it interacts with your cells, tissues, and overall health.
Red and near-infrared light have longer wavelengths, allowing them to reach deeper layers of the body. This is what makes Red Light Therapy (RLT) so powerful—it can stimulate cellular activity below the skin’s surface, impacting healing, circulation, energy production, and inflammation.
Our bodies are naturally photosensitive, meaning our cells respond to light in specific ways. Just like sunlight triggers vitamin D production, red and near-infrared light stimulate the mitochondria—our cellular powerhouses—to generate energy (ATP).
This boost in cellular energy helps repair damaged tissues, improve blood flow, and reduce inflammation—making Red Light Therapy a science-backed way to support long-term health and wellness.

The Top 7 Long Term Benefits of Red Light Therapy
1. Boosts Cellular Energy & Metabolism​
Every function in your body relies on cellular energy, and Red Light Therapy directly fuels this process by stimulating the mitochondria, the energy powerhouses of your cells. By increasing ATP (adenosine triphosphate) production, cells function more efficiently, leading to faster healing, improved organ function, and better overall energy levels.
4. Supports Joint & Muscle Health
Whether you're recovering from an injury or simply dealing with daily aches and pains, Red Light Therapy provides relief by reducing stiffness, increasing circulation, and accelerating tissue repair. Studies have shown that it can help reduce joint pain from arthritis, speed up post-workout recovery, and even enhance muscle endurance.
2. Reduces Inflammation & Speeds Recovery
Chronic inflammation is at the root of many health issues, including joint pain, muscle soreness, and slow recovery from injuries. Red Light Therapy helps regulate the body’s inflammatory response by increasing natural anti-inflammatory compounds while reducing oxidative stress. ​
5. Enhances Brain Function & Mental Clarity
Your brain needs energy just like the rest of your body, and Red Light Therapy has been shown to increase blood flow to the brain, supporting cognitive function, memory, and focus. By reducing inflammation in brain cells and enhancing mitochondrial function, it may even help protect against age-related cognitive decline and conditions like Alzheimer’s and dementia.
6. Promotes Deep, Restorative Sleep
Exposure to Red Light Therapy can help balance melatonin and cortisol levels, both of which play a key role in sleep quality. Unlike blue light from screens, which disrupts sleep patterns, red and near-infrared light support the body’s natural sleep cycle, helping you fall asleep faster and experience deeper, more restorative sleep.
3. Supports Skin Rejuvenation & Collagen Production
One of the most well-known benefits of Red Light Therapy is its ability to stimulate collagen and elastin production, which are essential for maintaining firm, youthful skin. By improving circulation and reducing oxidative stress, Red Light Therapy helps smooth fine lines and wrinkles, even out skin tone, and improve overall skin texture. ​
7. Improves Circulation & Cardiovascular Health
Healthy circulation is essential for delivering oxygen and nutrients throughout the body, and Red Light Therapy has been shown to enhance blood flow and oxygenation at a deep level. This increased circulation supports faster healing, reduces muscle soreness, and even improved cardiovascular function by helping to maintain healthy blood vessels and reducing oxidative stress.
How To Get the Most Out of Red Light Therapy-
The Cumulative Effect
If you’ve ever wondered why some people experience dramatic transformations with Red Light Therapy while others see only mild results, the answer is simple…consistency is the key to unlocking its full potential.
​
Red Light Therapy is much more than just a relaxing wellness treatment—it’s a science-backed approach to cellular rejuvenation, energy restoration, and long-term healing. But just like exercise or healthy eating, one or two sessions won’t create lasting change. The real impact happens over time.
​
Each Red Light Therapy Session Builds on the Last
Studies show that Red Light Therapy works cumulatively, meaning each session builds on the last, gradually increasing cellular energy production, reducing inflammation, improving circulation, and enhancing skin and tissue repair. While a single session may provide a temporary boost, it’s the consistent exposure that allows your body to fully heal, rebuild, and optimize function.
To truly experience lasting improvements in energy, pain relief, skin health, and overall wellness, the ideal protocol is 3-4 sessions per week for three months. After that, you can transition into a maintenance phase with 2 sessions per week to continue supporting your body’s long-term vitality.
​​​
For people over forty…this commitment is especially important. As we age, mitochondrial function declines, inflammation increases, and collagen production slows down—all of which can lead to fatigue, joint pain, sluggish metabolism, and skin aging. Red Light Therapy directly counteracts these effects by fueling your cells with the energy they need to repair and thrive.
By making Red Light Therapy part of your weekly routine, you’re not just investing in short-term relief, you’re supporting your long-term health in a way that’s natural, non-invasive, and scientifically proven to work.
Why Combining Red Light Therapy with Infrared Sauna is So Powerful
Red Light Therapy and Infrared Sauna are both powerful wellness tools on their own, but when used together, their benefits are amplified, creating a synergistic effect that enhances healing, recovery, and overall well-being.
Red Light Therapy works at the cellular level, delivering targeted wavelengths of light that increase energy production, reduce inflammation, and support tissue repair. Infrared Sauna, on the other hand, works by penetrating deep into the body with infrared heat, which boosts circulation, promotes detoxification, and relaxes muscles and joints.
​
