The Science Behind Infrared Knee Massagers: A Deep Dive

The knee is the largest joint in the body. It comprises the meniscus, articular cartilage, collateral ligaments, and cruciate ligaments, so taking care of them is crucial.

Knee injuries come in various forms, like sprains, strains, and other more serious diseases like arthritis, etc., which can be caused by anything from standing to climbing. Whatever the cause, the solution is an infrared knee massager.

If you are reading this blog post, it could be that you are experiencing one form of knee pain or another. Stay with us as we explain the causes of knee pain and the science behind infrared knee massagers.

Causes of knee pain

Your knees have come a long way. It has endured a lot of stress from when you first began to walk as a toddler to where you are today.

All these movements: standing, moving, jumping, bending, kneeling, climbing, and kicking, cause tear and wear on the knee over time, particularly when combined with a poor diet that increases inflammation in the body.

Quite a large number of people have acute or persistent knee pain. A study has revealed that about 25% of adults experience knee pain.

A knee injury or inflammation might lead to acute pain. For this kind of knee pain to get better, it needs attention and massage. In severe situations, chronic knee pain caused by arthritis, an untreated inflammation, or a traumatic accident can become incapacitating.

Knee pain can be classified into the following:

  • Inflammation: gout, tendonitis, and bursitis
  • Degeneration, wear, and tear – runner’s knee, various types of arthritis,
  • Injury – torn ligaments, overuse, dislocation

Your movement can be hindered when you experience knee pain. And you can deal with this problem in many ways without using an invasive procedure. Let’s find out below what infrared knee massagers mean.

What is an infrared knee massager?

Infrared knee massagers are devices produced for the knee. They use infrared light technology to treat pain and inflammation in the knee.

Infrared knee massagers are meticulously produced with the knee joint in mind, how it targets the joint, and how it moves and fits.

It simply penetrates the joint tissue at the proper depth when strapped to the knee and activated, activating the joint and initiating gradual healing.

The main idea is that it will lessen the inflammation, reducing the pain and increasing the range of motion.

You will experience severe irritation if you load that joint. It only has a knee-specific focus to reduce inflammation, increase range of motion, and lessen pain.

The science behind the infrared knee massagers

Infrared knee massagers use innovative light-based techniques for treating pain and inflammation. Contrary to ultraviolet rays, which can damage the skin, infrared light promotes cell regeneration.

Energy waves known as infrared light (or rays) are invisible to the naked eye. The electromagnetic spectrum carries the rays and penetrates the skin’s surface.

Then it gradually increases the knee’s temperature to 107F/42C and above, inducing an artificially low hyperthermic environment.

A low fever is your body’s natural wisdom for battling an infection or inflammation. However, it’s not just the heat that promotes therapeutic deep healing. Infrared rays that mirror morning sunlight also give your knee the natural benefits it needs, like the vitamin D required.

The light from these massagers penetrates the skin and causes substantial physiological changes within the tissue. Wavelengths in the infrared range provide energy to cells, promote healing, and reduce pain and inflammation.

Certain wavelengths of infrared light are transmitted to the region of inflammation or injury, leading to cell healing.

When used consistently for therapeutic purposes, these massagers help heal the pain’s underlying cause. “Heal” is the essential term here; standard medical care does not provide that.

This is due to the infrared light’s exceptional ability to penetrate the innermost layers of skin, which enables it to significantly lessen pain. It is also painless, natural, safe, and non-invasive. As a result, it will be able to offer a variety of health benefits.

Using infrared light therapy to relieve knee pain

The light targets a few key mechanisms to lessen joint pain without getting too technical.

It boosts cell activity, including specific substances like serotonin and acetylcholine, synaptic activity, and hormone synthesis.

Naturally, when these processes are boosted, It leads to regulation and tissue growth. It also lessens and inhibits bradykinin, which damages joints, effectively lowering the hormone’s potential. It merely increases mitochondrial potential.

The photons inside the mitochondrial cell or mitochondrial cells detect the red light as it penetrates the joint. Therefore, it increases the activity of those cells.

This expands all of these pathways while also increasing light transfer. It brings about a big dose of healing to the joint. It further causes biochemical changes that result in major joint changes and have numerous therapeutic benefits.

Such stimulation of cellular proliferation results in reduced inflammation, which undoubtedly, enhances the range of motion and lessens pain. It gets the knee joint firing and wakes it up, igniting the neuronal interactions.

Below is how the infrared knee massagers relieve pain

i. Infrared light penetrates approximately 2 to 7 cm deep into the skin, muscles, bones, and ligaments. It boosts and improves circulation and helps bring oxygen and nutrients to the knee, boosting healing.

ii. By promoting mitochondrial activity within your cells, the infrared knee massagers promote the growth and repair of new muscle cells and tissues, which is one extremely significant way it heals.

iii. The device demonstrates its usefulness for lowering muscle fatigue and enhancing muscle recovery. Endorphins are your body’s natural painkiller hormones that help fight inflammation and lessen pain by increasing endorphin release.

iv. For decades, light therapy works in clinical settings to treat arthritis. Therefore, patients with osteoarthritis, rheumatoid arthritis, and other inflammatory joint disorders can heal effectively using the device.

Infrared photons open capillaries to enhance circulation and promote tissue repair.

v. One of the main causes of water retention, which frequently results in swelling knees and legs, is sluggish lymphatic flow. Infrared knee massagers help in enhancing lymphatic drainage and minimize swelling.

vi. It boosts the formation of white blood cells that destroy harmful bacteria if your knee is infected. Your body naturally produces white blood cells as a form of defense.

Why are infrared knee massagers widely used?

Numerous medical specialties use infrared therapy, including those in dentistry, veterinary medicine, and autoimmune illnesses.

The therapy is safe and natural, making it possible to give it as a complementary treatment for various medical ailments, including arthritis, stiff joints, muscle pain, etc.

The body uses this method for many reasons. This includes relaxation, pain relief, improved circulation, detoxification, and decreased muscle strain.

Benefits of infrared knee massagers

There are many benefits to using infrared knee massagers. They include the following:

1. Help to improve circulation

Infrared knee massagers improve the circulation of oxygen and nutrients to the knee joint, which helps to lessen pain and swelling. Increased circulation can hasten the healing process and lessen the chance of further knee injuries.

2. Reduce inflammation

Infrared knee massagers efficiently improve blood flow and circulation, which helps promote healing and reduce inflammation.

3. Reduces pain

An infrared knee massager is very efficient when it comes to reducing pain in the knee. The device does this by reducing tension in the muscles and stiffness. This leads to increased blood flow and the breakdown of painful scar tissue.

The individual feels relieved once there is increased blood flow and circulation around the knee.

4. Increased flexibility and range of motion

This is one of the many benefits of using an infrared knee massager. The knee joint’s surrounding muscles can move more freely thanks to the device. As a result, it reduces the knee’s stress and stiffness, which can increase mobility.

5. Promotes healing

Unlike other forms of treatment that may relieve the pain temporarily, infrared knee massagers, when used consistently, can completely heal the knee injury. But this is a gradual process.

6. Improved athletic performance

Knee pain or injury limits the performance of athletes. With less muscular tension around the knee, athletes can move more easily with a lesser chance of injury. These help the players in maximizing their potential and enhancing their athletic performance.
