Scientists Andre Geim and Konstantin Novoselov from the University of Manchester in the UK, using simple tools and an ingenious method, successfully peeled away layers from graphite flakes using adhesive tape, ultimately obtaining graphene composed of just a single layer of carbon atoms. The creation of graphene not only earned them the 2010 Nobel Prize in Physics but also unveiled the mysteries of this new material to humanity. This material excels not only in optics, mechanics, and electricity but also demonstrates immense potential in various fields such as energy and biopharmaceuticals. Consequently, graphene has been hailed as a hallmark of 'high-precision, advanced technology' and 'black technology.' However, the reality is not always so straightforward. Currently, many cutting-edge graphene-based products, such as graphene batteries, still face technical challenges or insufficient market demand. Conversely, in sectors closely related to people's livelihoods, like medical treatment and healthcare, the application of graphene has already achieved remarkable results.

So, since both involve energy transfer, why is the heat generated by graphene more easily absorbed by the human body? To answer this, we first need to understand the principle of energy conversion. According to the law of conservation of energy, the total energy in the universe is constant; it can only be converted by changing its form. For instance, electrical energy can be converted into thermal energy and transferred through thermal radiation, conduction, and convection. The primary carrier of thermal radiation is infrared rays. Next, we will delve into the uniqueness of graphene in energy conversion and transfer.

Since both are infrared, why is far-infrared specifically known as the 'life ray'?
The light waves radiated by the sun to the earth include visible light waves (such as red, orange, yellow, green, blue, indigo, violet) and invisible light waves (such as infrared, ultraviolet, X-rays, etc.). Within the wavelength range of light, the portion from 0.75 micrometers to 1000 micrometers is called infrared. Far-infrared, as a specific band within infrared, is revered as the 'life ray' due to its unique wavelength range and biological effects.

Through in-depth medical research, scientists have discovered that the infrared wavelengths emitted by the human body are primarily concentrated in the 6-14 micrometer range. When the human body is exposed to light wave energy within this wavelength range, the water molecules in the body's cells resonate with it. This resonance effect promotes the dilation of micro blood vessels, improves blood circulation, accelerates metabolism, and significantly enhances the body's immunity and healing capabilities. Because of this, far-infrared rays within this specific wavelength band are acclaimed as the 'life ray.' Today, in the medical field, graphene is leveraging this unique property to create significant value. Breakthroughs have been made in research areas such as tumor hyperthermia, alleviating inflammatory pain, and boosting immunity.

So, why are graphene's far-infrared rays more easily absorbed by the human body? This advantage stems from the high degree of overlap between its wavelength range and that of the far-infrared rays emitted by the human body. When a graphene heating film generates heat, it releases far-infrared wavelengths concentrated in the 6-14 micrometer range. This range is almost perfectly aligned with the far-infrared wavelengths naturally emitted by the human body. It is this highly compatible wavelength range that allows graphene far-infrared rays to be absorbed and utilized by the human body more efficiently.

After rigorous testing by the National Infrared Center and comparison of the far-infrared wavelength concentration ranges of various materials, we found that graphene's far-infrared wavelength closely matches the human body's own far-infrared wavelength, both concentrated within the 6 to 14 micrometer range. Among numerous heating elements, why are graphene's far-infrared rays absorbed so efficiently by the human body? This is attributed to its exceptional wavelength compatibility. Compared to traditional heating materials like electric heating wires and stone needles, graphene's far-infrared wavelength demonstrates superior overlap with the human body's wavelength range, thereby ensuring its health benefits for the human body are more pronounced.

Far-infrared rays have been proven in the medical field to have significant therapeutic effects. However, the energy differences carried by far-infrared rays from different sources can profoundly alter their impact on the human body, sometimes even leading to vastly different outcomes. A difference of just 1% can determine the profound effect of far-infrared on the human body. The human body is like a complex machine, and the source and energy differences of far-infrared are akin to the process of digging a well to reach water. While carbon fiber and electric heating wires can also release far-infrared, their wavelength ranges do not completely overlap with the human body's far-infrared, resulting in lower efficiency. It's like digging a well and only reaching a depth of 9 or 10 meters, taking weeks. However, graphene can efficiently reach a depth of 10 meters in just a few days. This explains why graphene far-infrared is more easily absorbed by the human body. The 6-14 micrometer far-infrared waves it releases, known as 'life rays,' effectively induce resonance at the same frequency, allowing energy to be conducted more efficiently to the human body, thereby yielding superior health benefits.
