From red light therapy popping up on the most popular celebrity’s social media pages to medical professionals worldwide recommending the treatment, red light therapy has certainly got people talking.
Unlike other treatments that are invasive or laden with dangerous side effects, red light is a more gentle approach that can help with numerous conditions and in the aftermath of injuries.
Whether you’re looking for support with pain or are hoping to ease your way back to the gym after an injury, we’ve listed everything you need to know about red light therapy.
What is red light therapy?
Red light therapy, also known as photobiomodulation, uses LED lights to emit red light that is absorbed by the body's cells.
The red light wavelengths sit within the visible light spectrum and range from 620 nm to 750 nm. Due to its wide-reaching wavelengths, red light can go deeper into and below the skin.
When red light is placed against the body, the wavelengths stimulate the mitochondria - the energy-producing center of the cells. This absorption helps to promote natural biological processes, such as increasing collagen production, improving blood circulation, and reducing inflammation.
These processes mean that RLT is particularly known for its therapeutic effects on the human body, spanning skin rejuvenation, wound healing, muscle recovery, and pain reduction.
The origins of red light therapy
The origins of red light therapy may be simpler than you’d imagine as our relationship with light as a healing source can be traced back to our natural relationship with sunlight.
Early cultures, such as the Egyptians and Greeks, harnessed sunlight for its therapeutic benefits, constructing temples and engaging in sun-worship rituals for rejuvenation and healing.
This historical connection to natural light laid the foundation for modern red light therapy, which evolved from the broad use of sunlight to the targeted application of specific light wavelengths.
The invention of the incandescent lightbulb by Thomas Edison in 1879 marked a significant turning point, as it introduced the possibility of artificial light sources that could be manipulated for therapeutic purposes.
A pivotal moment in the history of red light therapy then occurred when NASA uncovered the significant healing potential of light.
During space missions, NASA scientists observed that astronauts exposed to certain light wavelengths experienced faster wound healing. This unexpected discovery spurred further investigation into how light influences the body’s regenerative processes.
Through detailed scientific studies, NASA researchers found that red and near-infrared light wavelengths could penetrate deep into the skin, activating cellular processes and boosting the production of adenosine triphosphate (ATP), the primary energy source for cells, thereby accelerating tissue repair and regeneration.
With NASA’s influence, their research into the use of light therapy for wound healing marked a major moment in the awareness of light.
The development of light therapy has progressed rapidly since with advancements in technology, particularly with the introduction of lasers and LED (Light-Emitting Diode) technology. Lasers allowed for precise targeting of light to specific areas, while LEDs offered a versatile, energy-efficient means of delivering therapeutic wavelengths.
Today, red light therapy continues to gain popularity for its ability to stimulate cellular processes, reduce inflammation, and promote healing across various medical and wellness fields.
How does red light therapy work?
While the science behind red light therapy might seem complex, the core concept behind how red light therapy works isn’t as daunting. This treatment revolves around the ability of red and near-infrared light wavelengths to activate cells and tissues in the body, triggering a series of beneficial biological reactions.
When these light wavelengths penetrate the skin, they are absorbed by the mitochondria, the energy-generating powerhouse that produces adenosine triphosphate (ATP). This absorption boosts ATP production, increasing the cell’s energy levels and enhancing its ability to carry out various functions.
It’s also able to modulate the body’s inflammatory response as it encourages the release of anti-inflammatory molecules.
So, whether it’s used for skin rejuvenation, hair growth, pain relief, or joint health, red light therapy can offer a wide range of benefits by energizing cellular function and bolstering the body’s innate healing abilities.
What types of red light therapy are available?
Advancements in technology have made the therapy much more accessible, with the practice now coming in various forms.
The types of red light therapy include:
- Masks
- Panels
- At-home devices
- Clinic devices
Each one serves a particular purpose, with the masks being predominantly used for skincare purposes. While there are RLT-focused masks that can be purchased for at-home use, clinics worldwide offer the practice in a dome format too. This is where your body would be under a large RLT device.
Another option is the panels which vary in size and length. Some are full body length whilst others are smaller panels that you can prop against a desk or table.
While these are good for use at home as they are standalone, the panels have difficulty in targeting deep tissues as the light intensity reaching the skin is low. This is because it’s not focusing on one area, but is trying to reach every area all at once. This results in an uneven distribution of light and a lack of control over treatment parameters.
On the other hand, you then have at-home devices that are smaller and focus on specific areas of the body like Kineon’s MOVE+ Pro. This device is completely portable and can target areas that are causing you the most pain or discomfort.
It can be taken on-the-go too, meaning you can carry out your daily tasks and chores while being able to experience the healing powers of light.
What conditions can benefit from red light therapy?
There are a range of conditions that can benefit from red light therapy including chronic pain, muscular pain, traumatic injuries, surgery pain, sports injuries, arthritis, and so much more.
The below list includes just a few:
- Inflammation: Science shows that photobiomodulation causes the suppression of chemicals that fuel inflammation while triggering the release of chemicals that actively fight it.
- Fertility: Reproduction requires a lot of cellular energy which is what is promoted when red light is applied. The light can promote healthier cellular activity and improve blood circulation to the reproductive organs.
- Arthritis: The therapy can lower inflammation in the joints, relieve stiffness, and reduce the pain.
- Wound healing: Stimulated cell proliferation, enhanced collagen production, and improved blood circulation are all benefits that are useful for wound healing.
- Fibromyalgia: Red light can help those with fibromyalgia through its improvement in blood flow and mobility, as well as the reduction in inflammation.
- Sports recovery: The red light wavelengths are known for speeding up the recovery process as they can deliver much needed oxygen and nutrients to the cells faster which accelerates tissue repair.
- Sciatica: Red light’s anti-inflammatory approach means that inflammation and pain can be reduced, bringing about greater mobility.
- Tendonitis: Collagen is a crucial protein that provides strength and structure in various tissues in our body. When more is produced through light therapy, this can help the repair and remodeling of damaged tendon tissue.
Is red light therapy effective?
Red light therapy is effective and its results have been shown throughout various studies and research papers.
It’s generally recommended for at least two weeks of consistent use to see results, but it does depend on the individual and how reactive their body is. Some people report joints feeling ‘looser’ after one fifteen-minute session.
To gain the most out of RLT, you should be using the treatment on a regular basis. A 15-20 minute session every day or four times a week is better than 50 minutes every few weeks.
Where to get red light therapy
Now that it’s a lot more popular, you’ll notice many spas, beauty salons, clinics, and wellness centers have red light therapy treatments. This could include facials, beds, and even stand-up tubes that you can walk into.
Some doctors will suggest the practice if they believe it’ll be beneficial for you and dermatologists offer it at their office.
If you’re looking to implement red light into your life, but aren’t so eager to have to visit a specific location every time - consider an at-home device. With this, you can carry out and complete the treatment anywhere that is most suitable for you.
