Since FIR (FIR) are able to hatch the eggs of insects, sea turtles, chickens and other animals, causing them to develop blood vessels, nerves, skeleton, skin and feathers, it can similarly cause changes to the human body.

Our bodies are made up of cells, and the most important ingredient in cells is water. Water makes up 65% to 70% of mass of the human body. The cells in the body in turn forms the various organs such as the heart, liver, kidneys, digestive organs, blood vessels, nerves, bones and skin. Just as FIR are able to cause the albumen and egg yolk to develop into various organs, it is able to activate, revitalize, reactivate, develop and strengthen the various organs in our bodies when it is absorbed.

In the various organs of the human body, the circulatory system plays an important role, especially the micro-circulatory system. It is basis of the sustenance of life because if it deteriorates, death is likely to follow. When there are problems with the micro-circulatory system, various ailments will occur. FIR vibrating at a frequency similar to that of the human body is able to penetrate to the body, activate the cells and reactivate as well as strengthen the micro-circulatory systems. It regulates the blood flow and blood in blood vessels which have been blocked due to blood clots and at the same time reactivate the vital energy in the body. That is why we say that FIR are able to regulate the blood circulatory systems of the body, especially that of the micro-circulatory system.

The various activities of the human body depends on the supply of nutrients. Nutrients ingested into our bodies provide us energy and help sustain our lives. At the same time, waste matters which are produced after the nutrients have been absorbed have to be removed from the body. The process is known as metabolism.

The metabolic rate of each individual is an indicator of his/her health. If we wish to have a healthy life, we must maintain a good and strong metabolic rate. FIR area able to improve blood circulation and continuously uplift the metabolic rate of the body. As the transport of the nutrients in the body depends on blood circulation, the removal of metabolic waste matters from the various activities in the body is also dependent on the circulatory system. When the circulatory system is improved under the influence of FIR, it will naturally improve our metabolism. As such, the second benefit that FIR provides for the human body is the elevation of metabolism thus improving energy and vitality.

Its third benefit is elevation of the immunity of our bodies against diseases. This is part of the effects of the improvement in the micro-circulatory system and metabolism of the body. It helps to slow down the aging process, increase resistance against diseases and increases longevity.
