In this blog post, we’ll discuss both the advantages and limitations of red light therapy belts and help you decide if using one is right for you. We’ll also discuss some precautions to take while using a RLT belt so you don’t end up hurting yourself in any way. Before you make a purchase, it’s important to know some of the advantages and limitations of the red light therapy belt.

The advantages and limitations of using RLT belts.

Red light therapy belts have been gaining popularity in recent years as a treatment for a variety of conditions. They work by emitting red light through a flexible pad that is attached to the skin near the area to be treated. Both red light therapy belts and panels work through the same photobiological mechanism, as we have discussed thoroughly in the blog, the pros and cons of RLT therapy.

The common benefits associated with RLT belts includes:

  1. Stimulate collagen production, to promote skin appearances
  2. Reduce scars and stretch marks
  3. Reduce inflammation and treat acne vulgaris or other inflammatory conditions, including chronic inflammatory diseases, like Psoriasis and Rosacea.
  4. Treat hair loss and stimulate hair regrowth
  5. Accelerate weight loss and reduce cellulite
  6. Help muscle repair and soreness
  7. Help pain recovery including chronic pain to achieve long-lasting pain relief.
  8. Accelerate wound healing to help recovery from injuries

The special narrow bands of red and near-infrared lights can penetrate into the skin and activates the photodynamic modulation, through photoreceptors, which leads to the metabolic stimulation and many beneficial effects. It is recognized as a safe treatment strategy that is both minimally invasive and minimally toxic.

But what are special benefits of using a RLT belt? What is the deal with RLT belts? Compared with versatile RLT panel, do I need a RLT belt? There are specific advantages of RLT belts.

RLT belts are convenient to use, because they are lightweight, thin and can effectively attach around any area of your body, including parts that are difficult to access, such as the shoulders or the knees. It will reduce your efforts when healing such areas, due to its more flexibility of design,since you don’t need to stay in particular body position to allow maximized irradiation to shine on your targeted areas, and it allows your movement during light treatment. That makes the RLT belts specialize in treating knee pain (arthritis), cellulite reduction, muscle recovery in such areas and so on.

The secondly primary benefit is that, compared with other light sources, LED light bulbs produce less heat and thus can be directly used on the skin. Since light wave can’t go through clothing, the treatment through red and near-infrared light require the light to reach bare skin in order to be effective, so direct attachment is more beneficial to targeted treatment, in comparison with a light shower under irradiation of light panels. Unlike the light shower, you don’t need to maintain unclothed during treatment, and pads, however can be placed under clothing anywhere and allow for deeper penetration and greater absorption.

Compared to panel systems, pad systems have various benefits. Most people purchase a light treatment system in order to lessen the pain brought on by recent or chronic conditions such as joint or back pain, muscular spasms, arthritis, and foot and limbs discomfort. As a result, targeting the light with flexible pads that touch the skin should be more efficient and effective than spreading it out over a greater area that is at least 6 to 12 inches away from the body.

However, there are some limitations behind red light therapy belt systems. The most important one is that the direct contact with the skin requires less intensity and LED bulbs to avoid heat production and the associated uncomfortable feelings or common side effects from light therapy. So flexible pads are usually limited by the amount of overall power and intensity they can deliver. And what is more, because they thin in design and often lack a cooling system, they usually are much less powerful than the panel counterparts.

The next negative is that for many untested products in the market, the emitting EMFs directly irradiate on the skin is a major problem. Due to the technology limitations, many products still emit high unwanted EMFs and you may need other tricky approaches for reducing EMFs.

How to choose a reliable and high-quality red light therapy belt?

When it comes to red light therapy (RLT), it’s important to do your research and make sure you’re choosing a device that’s safe and effective. There are a lot of options out there, so it can be tough to decide which one is the right fit for you. Here are some key points to keep in mind when shopping for an RLT belt:

1) Make sure the model has been verified by the FDA as safe and effective.

2) Choose a belt that emits narrow beams of red light, which are more targeted and safer for your conditions.

3) Be aware that cheaper belts may not have been tested or certified, so be cautious before making a purchase.

The most important concerns to choose a RLT belts are the number of LEDs, intensity (power), EMF radiation, size, weight, and pad material.

1) Belt size and treatment area

The treatment area of the LED wrap is the vicinity which of the place the LED bulbs are, and you have to make sure it is massive adequate for your specific needs.

2) Irradiation and intensity

Irradiation and intensity have the same unit and both are measured in mW/cm^2. Intensity is determined by the number of LEDs and the conversion rate of light energy. It should be noted that without adequate amount of irradiation, the light treatment won’t produce effective result, no matter how long you extend the duration. Especially for the areas, where the light need to penetrate through fats and bones, like knees, hips, abdominal areas. The irradiation will directly limit the penetration ability of light wavelengths and therapeutic effects.

3) Wavelengths

Most RLT belts provide single wavelength system, and only few providers can surely provide dual system with both red (usually around 660 nm) and near-infrared (830 nm) light wavelengts, which are the most well-studied and proven most effective range. Though either red light or near-infrared light alone can be effective to treat numerous conditions, in some studies, especially for psychiatric problems and brain-related conditions, the mixed solution shows a better outcome than the single wavelength because the longer wavelength can amplify the effect of the shorter wavelength. The better result comes from the combination of different depths, photon scattering, and direction change, which creates a net effect around the treatment area, and the mixed wavelengths are believed to trigger more synergistic processes. 

4) EMF Radiation

We all know that EMF radiation, emitted by all electric powered devices can be damaging to our bodies and higher-frequency EMFs in the ionizing radiation part of the electromagnetic spectrum can damage DNA or cells directly. A good-quality RLT belt is equipped with EMF shielding technology to avoid it.
