Application of Red and Near Infrared Light Therapy In Health
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 instrument? Is infrared therapy useful after all?
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 can be roughly divided into three parts, that is:
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.
Among them, the near-infrared wavelength of 760nm-2000nm is the light with the strongest penetrating ability among the light that can be treated by the human body, and its energy can reach 8~10cm deep into the subcutaneous tissue, penetrating the cortex and subcutaneous tissue directly to the bone and viscera.
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.
From the point of view of human cells, infrared ray activates tissue cells. When the human body is irradiated by infrared light, it can cut off the long chain of some associating macromolecular groups (30 ~ 40 water molecules) in the body and form small molecular groups composed of 5 ~ 6 water molecules, so that the number and speed of water molecules into the cell membrane is greatly increased. On the one hand, the cells are cleaned to strengthen the discharge of toxic substances; On the other hand, strengthen the exchange of oxygen and nutrients and other material energy, so as to enhance the activity of calcium ions in cell membranes and cells.
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:
As can be seen from the spectrogram, the permeability of near infrared is stronger, reaching 8~10cm deep to 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 devices?
Professionalism: whether belong to medical apparatus and instruments, have medical apparatus and instruments registration certificate, a lot of non-medical apparatus and instruments.
Whether the light source is pure: the lamp is the most critical, whether the wavelength is 760nm~2000nm medical grade near infrared light source. Whether the light is uniform, whether the illumination area is large.
Whether it is safe to use: whether the material is good, whether there will be a burnt taste when the irradiation begins, whether it will fall over when placed at home.
