The Effect of Far Infrared Rays on Living Organisms

Most humans like to go to hot springs, bask in the sun, do aerobic exercises, etc., which are specific behaviors that humans need far-infrared rays to keep the body healthy. In fact, the ultimate goal of these actions is to promote blood circulation and keep the body healthy.


Metabolism is the general term for biochemical reactions in organisms. That is, the role of material and energy exchange between organisms and the environment. Or the self-renewal process of matter and energy in the organism. The following two processes are included.

  • Metabolism assimilation
  • Liquefaction of catabolism

Conditions of biochemical reaction:

  • Reactions: biomolecules such as food, protein, carbohydrates, lipids, etc.
  • Energy: use to stimulate the progress of the reaction.
  • Catalyst (enzyme): Provides catalysis and accelerates the progress of biochemical reactions.

Far infrared rays can be the energy that only the base polymer resonantly absorbs, so it is easy to act on the reactants of the biochemical reaction and promote the progress of the reaction.

Biochemical reactions of cells and far infrared rays:

After cells receive far infrared rays, they can increase their resonance energy, promote cell activity (activate cells), further accelerate metabolism, contribute to cell proliferation and the synthesis of biochemical substances of various enzymes, catalyze the progress of biochemical reactions and improve the functioning of the immune system.

At the same time, after cells receive far infrared rays, they will increase their resistance to harmful substances (oxidative free radicals). Increase the antioxidant capacity of cells, and at the same time increase the life cycle of cells.

Far infrared rays will activate the cells and water in the human body to initiate activation; improve the solubility and penetration of water and the efficiency of biochemical substance transport, and help the progress of biochemical reactions. Therefore, far infrared rays are of great help to human health.

The mechanism of far infrared rays in cells (cell activation, promoting the synthesis of enzymes and antioxidants and other biochemical substances, and then generating benefits to the cardiovascular system), take the five mechanisms of action in blood vessels as example.

  1. Far infrared rays increase the activity of vascular endothelial stem cells (a precursor that can be activated into endothelial cells).
  2. Heme oxygenase, an inducible isomer catalyzes the cleavage of heme into two antioxidants, bilirubin and carbon monoxide.
  3. Increase the laminar shear stress by increasing the peripheral blood flow and stimulate the expression of endothelial nitric oxide synthase eNOS.
  4. Directly stimulate eNOS and increase the production of nitric oxide in blood vessels, thereby coordinating and improving the function of blood vessels.
  5. Far infrared rays stimulate the expression of nucleated red blood cells 2 like transcription factor 2 (Nrf2). Nrf2 can regulate the expression of antioxidants by becoming with the endogenous antioxidant response element (ARE) in the nucleus.

Far infrared rays, body temperature and immune system:

Far infrared rays increase body temperature, stimulate the immune system, activate sweat glands to remove toxins from the body, and accelerate the heartbeat to improve blood circulation. Far infrared rays have a longer wavelength, which heats the skin deeply. At the same time, far infrared rays can activate cells and water molecules, promote the synthesis of various biochemical substances, promote perspiration, and eliminate toxins from the body.

Far infrared rays and water:

  • The main role of 70% water in the human body is to act as an electrolyte that acts as an ion conduction pathway in biochemical reactions. Provides more reactants and products in and out, and water with improved solubility can increase the rate of biochemical reactions.
  • The hydrogen bonds in the water molecules will produce agglomerates (large molecular water clusters), which have low solubility and permeability. Far infrared rays can weaken hydrogen bonds,, change water into small molecular clusters, increase activity, and facilitate the progress of biochemical reactions.
  • The reaction of far infrared rays to water is best carried out at the same time as the biochemical reaction to avoid the reduction from small molecular clusters to large molecular clusters (the original equilibrium state before the far infrared radiation). At the same time, the effect of treating water with far infrared rays has a great relationship with the impurities in the water.
  • The water irradiated with far infrared rays has higher evaporation, high solubility, better fluidity, lower viscosity, and higher permeability.

The benefits of far infrared rays on living organisms:

  • Assist or directly improve symptoms
  • Maintain health
  • Improve cell anti-oxidation and anti-inflammatory ability
  • Improve cardiovascular function
  • Improve muscle soreness and exercise recovery
  • Promote circulation and pain relief
  • Activate cells to promote metabolism

The effect of far infrared rays is cumulative, and it takes a long time to use it to produce a significant effect. Improve the relief of symptoms such as aging, chronic diseases and long-term discomfort, and improve the quality of life.


Hydrogen peroxide is a by-product of the normal metabolic process of animal and plant cells.

Peroxidase can decompose hydrogen peroxide into water and oxygen. Control the concentration of hydrogen peroxide not to be too high, causing cell toxicity. Because superoxide and hydrogen peroxide are the main sources of reactive oxygen radicals (ROS).

Far infrared ray can affect the intracellular:

  • The concentration of H2O2 decreases.
  • NADP + <oxidation form of reduced coenzyme> / NADPH <reduced coenzyme> ratio, that is, the straight increase in the presence of oxidants.
  • Cytochrome C decreased

Therefore, it is estimated that far infrared rays can improve the antioxidant properties of cells. As we age, cells will rapidly age and die. The harmful factor that causes cell aging and death is oxidative free radicals. Therefore, we need to reduce free radicals or improve the ability of cells to fight with them in order to maintain the normal operation of cells. Far infrared rays can assist organisms in removing H2O2.


Cyclooxygenase (COX) is usually produced in the inflamed area, that is, a large amount of COX-2 is usually accumulated in the inflamed area; pharmacologically, inhibiting COX can inhibit the symptoms of inflammation and pain. Hydrogen peroxide will increase the amount of COX, and far infrared radiation will inhibit the production of COX.

The function of maintaining the health of vascular endothelium and reducing inflammation:

Far infrared can reduce the activity of IL-6 (level and interleukin 6) and TNF-α (tumor necrosis factor α), and can stabilize eNOS (endothelial nitric oxide synthase) and affect the concentration of cytokines in plasma.

Improve cardiovascular function:

  • Far infrared rays increase the shear force (shear stress) of blood flowing through the blood vessel wall, stimulate eNOS (endothelial nitric oxide synthase), increase the production of nitric oxide, and derive various cardiovascular protective mechanisms.
  • Nitric oxide is an important vasodilator. Through vasodilation, arterial diseases (such as platelet aggregation and smooth muscle cell migration and proliferation) can be inhibited, and the development of atherosclerosis can be prevented.
  • Far infrared rays can increase the secretion of insulin and reduce the secretion of glucagon, reduce oxidative stress, and then promote blood flow recovery and form cardiovascular benefits, and improve the symptoms of diabetes.
  • Improve chronic kidney disease: Far infrared rays promote endothelial function (through far infrared rays, induce the performance of heme oxygenase-1(HO-1), and provide powerful anti-inflammatory effects on vascular endothelium), which can benefit hemodialysis patients.

Far infrared rays can increase the blood flow into the kidneys and reduce the incidence of arteriovenous constriction. At the same time, the growth of vascular smooth muscle cells can improve hemodialysis and avoid the risk of vascular access stenosis.

Improve muscle soreness and exercise recovery:

Far infrared rays can improve the ability of cells to proliferate (help myoblasts fight hydrogen peroxide), and can also inhibit the production of lactate dehydrogenase. Far infrared rays can reduce the oxidative stress and relative soreness of muscle cells induced by exercise; the NO content in cells has a significant increase trend under far infrared rays.

Promote blood circulation:

Physical damage to the body caused by long-term poor posture, such as various aches and pains in the shoulders, neck and back caused by poor blood circulation.

Use far infrared chair cushions or related fabrics (such as blankets) to cover the painful area for at least one hour a day to achieve a certain improvement effect. This is because blood circulation is the pipeline responsible for the human body’s nutrients and biochemical products, which is vital to health. Another important effect is to improve the microcirculation of the skin, which can improve wound healing, reduce tissue edema, reduce ischemic pain and prevent refusion injury. The improvement of skin microcirculation also has specific benefits for preventing acute and chronic tissue ischemia such as trauma, reconstructive surgery, diabetes and peripheral arterial occlusive disease.

Far infrared rays promote the increase of blood flow speed is a non-thermal biological effect, but also a non-immediate response. Due to the low-energy and long-wavelength characteristics of far infrared rays, it can penetrate deep into the bottom layer of the skin and resonate with the frequency of the human body.

[the control of blood pressure lies in the regulation of nitric oxide by endothelial nitric oxide synthase (eNOS) synthesized in vascular endothelial cells. When the production of NO in blood vessels is reduced, it will reduce the vasodilation ability and cause the phenomenon of high blood pressure. Since the mechanism of far infrared rays is a biological function rather than a function of hyperthermia, there is the emergence of the stereospecific molecule NG-intro-L-arginine methyl ester <L-NAME> which inhibits eNOS activity. It also inhibits the effect of far infrared rays on blood flow velocity stimulation]

Activating cells and promoting metabolism: the biological effects of far infrared rays

Far infrared has a significant improvement effect on cell migration (as platelet growth factor-mediated skeletal muscle cells or L6 cells, chip analysis and quantitative real-time polymerase chain reaction), and it also verifies its effect on wound healing.

Chip analysis: in the analysis of DEG (differentially expressed genes), it was found that under the interaction between the extracellular matrix (ECM) and the receptor, it was found to improve the effects of  actin and integrin (a transmembrane receptor that mediates the connection between cells and its external environment), crown protein and its subunits.

The first conclusion:

  • Under the action of FIR (far infrared ray), ECM and platelet-derived growth factor (PDGF) mediated cell migration related genes have a significant increase.
  • Observe the migration of L6 cell lines under far infrared radiation, and conduct wound healing experiments. It is found that the area of the cell scratch gap becomes narrower at 24 and 48 hours, it has a significant improvement in wound healing.

The first conclusion is derived from the far infrared ray on the biological indicators (FIR) effect index (FBI). Use the promoted cell migration area as the basis for quantitative calculation.

The second conclusion:

  • Cell analysis proves that the most effective intensity of far infrared rays is 0.07-0.13mW/cm2, and the best irradiation time is 30 min (the FBI value is the highest).
  • Maintaining sufficient far infrared rays for a long time is still the way of health care anyway.

The relationship between FBI and mitochondria, we have the following conclusions:

  • Far infrared radiation increases the ratio of NAD+/NADH in cells.
  • Heat inhibits the biological effects of far infrared rays. The far infrared effect of ultra-low heat energy must be used to avoid affecting the FBI value.

Relieve pain and fatigue:

Far infrared rays have a higher oxygen intake during peak exercise and longer endurance time.

The anaerobic start value will have a significant delay time. Both the oxygen uptake and oxygen pulse at the beginning of anaerobic are increased, and the blood lactic acid concentration is lower.


  • Far infrared rays improve exercise capacity and achieve the effect of delaying anaerobic metabolism; specifically, it is presented as “the increase in peripheral delivery of oxygen through muscle vasodilation.”
  • The effect of delaying muscle soreness is better, and the quality of sports training is improved.
  • Before the test, the sympathetic activation (such as rapid heartbeat, vasoconstriction) for those who have the far infrared test effect is significantly higher than that of the testers without the far infrared. Personally, there will be a more obvious reduction in sympathetic activation. At the same time, the parasympathetic response (such as vasodilation) will be significantly reduced in both groups. Oxygen consumption during exercise and recovery will be reduced due to the effect of far infrared rays.
  • Reduced oxygen consumption means that far infrared rays have a negative effect on sympathetic reactions and a positive effect on parasympathetic reactions.
  • The reduced control of parasympathetic nerve activity (especially the heart) is the cause of physiological aging. Endurance training is to increase the activity of the parasympathetic nerve during exercise and reduce the activity of the sympathetic nerve during rest.
  • Far infrared can reduce fatigue and skin surface temperature after exercise, stabilize breathing and heart rate; these are the control of parasympathetic nerves. It can reduce resting energy expenditure after exercise and improve cardiorespiratory recovery.

Promote detoxification in the body:

The theory that perspiration is better than urination is mainly because there are fewer metal elements in sweat during perspiration, and it is less likely to excrete too many useful minerals due to detoxification (similar problems still occur when a lot of perspiration is performed). In addition, perspiration in an environment with high levels of poisons (for example, firefighters) will also cause skin to absorb poisons.

Compared with blood, sweat is a more sensitive body fluid; it contains more toxic elements such as cadmium, bismuth, antimony, and tin.

Boost the immune system:

Nitric oxide present in the blood is necessary for the immune system to produce an immune response against various bacterial and viral pathogens (sources of infection). Since far infrared rays have a positive effect on the increase of nitric oxide and inducible nitric oxide synthase, it also improves immune activity and increases the inducibility of immune activity. Whether it is in the reactivity of the innate immune system, or the effectiveness of the antibodies produced by the acquired immune system after the use of the vaccine, there is a high degree of positive benefit.

Activation of water molecules in organisms:

The resonance wavelength of water is between 2.7-6.3μm, so far infrared prediction can affect the hydroxide ion bonds (intermolecular) in water, increasing the energy absorbed by water molecules, producing an activation effect that promotes water molecules to participate in biochemical reactions.

Far infrared rays weaken the hydrogen bonds between water molecules in the body, resulting in the shrinking of water molecular aggregates, generating relatively high permeability and solubility, and increasing the ability to participate in biochemical reactions, which is called activated water.

According to the effects of activated water in the body, we have the following conclusions:

  • Bone cells have an antioxidant effect on H2O2-mediated toxicity.
  • Causes the production of cyclooxygenase-2 (COX-2), which improves anti-inflammatory and bone and joint health.
  • The acid-base value of activated water is higher, reaching 7.97-8.18 (unactivated water is 7.85-7.95). This is because activated water weakens the hydrogen bond of water and increases the amount of oxygen dissolved in the water; thereby increasing the acid-base value of the water.
  • Activated water can increase the absorption of nitrogen in food.
  • Increased metabolism and increased protein absorption rate.


Far infrared is a physical phenomenon that can produce resonance absorption with cells in the organism, and the series of physical and chemical effects derived are all positive. Far infrared rays cause more active cell and tissue activities in organisms, promote the action of biological enzymes, and produce important biochemical substances (such as nitric oxide and magnesium-calvin, etc.). Effective anti-oxidant and anti-inflammatory, promote circulation and metabolism, relieve nerve pressure and soreness, etc.

In addition, it is very important that the effects of far infrared rays are cumulative and require long-term use and attention to produce obvious effects. Therefore, we must first start by changing the inertia of physiological functions, and then maintain long-term health care.
