Near-Infrared Light Therapy and Red Light Therapy Applications in Health
What is Near-Infrared Light Therapy?
Near-Infrared Light Therapy is a groundbreaking approach in health and wellness that leverages the power of light to promote healing and improve overall well-being. This therapeutic technique utilizes near-infrared light, a form of electromagnetic radiation with wavelengths between 760nm and 2000nm, to penetrate deep into the body’s tissues. Unlike visible light, near-infrared light can reach several centimeters beneath the skin, allowing it to stimulate cellular processes and enhance circulation.
How Does Near-Infrared Light Therapy Work?
This form of therapy is renowned for its ability to reduce inflammation, relieve pain, and accelerate tissue repair. By increasing blood flow and encouraging cellular regeneration, near-infrared light therapy supports the body’s natural healing mechanisms. As interest in home-based health solutions grows, near-infrared light therapy offers a non-invasive and effective option for those seeking to improve their health and quality of life. In this guide, we will explore the principles of near-infrared light therapy benefits, and how to choose the right device for your needs
More and more people are paying attention to home medicine and are interested in the red and near infrared light. Usually when people buy infrared therapy instrument, there will be questions such as the following:
- What is the principle of near infrared therapy instrument? Is near infrared therapy worth buying after all?
- What is the difference between near infrared therapy and far infrared therapy?
- How to choose the therapy instrument on the market?
Read on, and I’ll take you through the answers to this puzzle.
What is the Principle of Infrared Therapy Instruments? Is Infrared Therapy Effective?
First of all, let me introduce what is red and near infrared light for you. Near infrared light is a electromagnetic wave with a wavelength of 1mm, between microwave and visible light. Physical characteristics are thermal effect, strong penetration. See spectra as below:
Infrared light can be roughly divided into three categories:
Near infrared, the wavelength is between (3~2.5)μm ~ (1~0.75)μm;
Medium infrared, the wavelength is between (40~25)μm ~ (3~2.5)μm;
Far infrared, the wavelength is 1500μm ~ (25~40)μm.
Penetrating Ability of Near-Infrared Light
Among these, near-infrared light with a wavelength of 760nm-2000nm has the strongest penetrating ability, reaching 8-10cm deep into subcutaneous tissue. It effectively penetrates the cortex and subcutaneous layers, reaching the bone and viscera.
Thermal Aggregation and Metabolic Effects
From the point of view of the human body, infrared ray has a very obvious thermal aggregation effect with the human body. Then I explain to everybody here, because of the near infrared light waves match the human body radiation, can produce the effect of warm, heat easily absorbed by the body tissue, and can cause vasodilation, blood flow speed, partial blood circulation improvement, organization to strengthen nutrition metabolism, because promote human metabolism, infrared, also known as “the light of life”; This can accelerate the absorption of local exudate, such as congestion and effusion, promote the subside of swelling, and improve the self-repair of joint and bone tissues.
Cellular Activation and Detoxification
From the point of view of human cells, infrared ray activates tissue cells. When the human body is exposed to infrared light, it breaks down long chains of macromolecular groups (30-40 water molecules) into smaller clusters of 5-6 water molecules. This process significantly increases the number and speed of water molecules entering the cell membrane. As a result, cells enhance the removal of toxic substances and improve the exchange of oxygen, nutrients, and other materials, boosting the activity of calcium ions in cell membranes and cells.
Improvement of Microcirculation
Near infrared can improve microcirculation. Microcirculation refers to the blood circulation in the microvessels between arterioles and venules. Its basic function is to realize the material exchange between the blood and tissue cells, transport nutrients (including nutrients and oxygen) and extract the waste (including carbon dioxide and metabolites), so the microcirculation is the body of the “second heart” under normal circumstances, microcirculation blood flow and metabolism of human body tissue and organ level, make the human body each organ physiological function to normal operation. When microcirculation dysfunction or decreased perfusion of microcirculation blood volume, tissue and organ dysfunction or failure can be caused due to failure to meet the needs of tissue oxidative metabolism, which is an important reason for the occurrence and development of many diseases.
Combined with the above principles, nIR therapy has been widely used in clinical treatment of inflammation. The application of infrared ray combined with functional exercise in the treatment of osteoarthropathy in middle-aged and elderly has achieved satisfactory clinical effect.
What is the Difference Between Near Infrared Therapy and Far Infrared Therapy?
Both near infrared and far infrared are helpful to the human body, the difference between near far infrared therapy instrument, in fact, involves the difference between near infrared and far infrared:
The spectrogram shows that near-infrared light has stronger permeability, reaching 8-10cm deep into the subcutaneous tissue.
Near infrared has higher energy than far infrared, and the therapeutic effect is more significant.
Medical grade infrared therapeutic devices mostly choose the near-infrared band with the pure light source wavelength of 760nm~2000nm.
How to Choose a Good Red Light Therapy Device
1. Professionalism and Certification
Ensure the device is classified as a medical apparatus and has the necessary medical registration certificates. Many devices on the market may not be certified medical-grade equipment.
2. Quality of the Light Source
The lamp is crucial to the device’s effectiveness. Ensure the light source is a pure medical-grade near-infrared light with a wavelength between 760nm and 2000nm. Additionally, assess if the light is uniform and if the device covers a sufficiently large illumination area.
3. Safety and Durability
Verify that the device is made from high-quality materials. Ensure there are no safety issues, such as a burning smell during use, and check the stability of the device to prevent tipping over when placed at home.
