Biological effects of terahertz activated water molecules

The biological effect of terahertz-activated water molecules represents a cutting-edge scientific phenomenon with significant implications for human health. As a special type of electromagnetic wave, terahertz waves can effectively penetrate human skin and directly act on deep tissues. Given that approximately 70% of the human body weight is composed of water molecules, and cells account for a considerable proportion of these water molecules, the binding state of water molecules is crucial for cellular activity.

Terahertz waves can activate water molecules, causing them to transition from a low-energy state to a high-energy state. This process not only reduces blood viscosity but also significantly enhances cell regeneration and immunity. Such activation helps improve human microcirculation, promotes metabolism, and thereby delays the aging process. Additionally, activated water molecules can more effectively eliminate toxins from the body, enhance mental vitality, and provide comprehensive health care and adjunctive therapeutic effects for the body. Therefore, the biological effect of terahertz-activated water molecules holds broad application prospects in the field of biomedicine.

Can terahertz waves lower blood pressure

1. Penetrating Biological Effect

Far-infrared terahertz waves can penetrate 3-5 centimeters into human skin, directly acting on deep tissues, replenishing life cell energy, regulating bodily physiological functions, and accelerating cell generation and decomposition.

2. Resonance Cellular Biological Effect

When the human body temperature is 36.5°C, it corresponds to 9.36 micrometer terahertz. When these wavelengths act on the human body, they can produce a phenomenon of resonance with cells at the same frequency, stimulating the movement of water molecules within the body, increasing blood oxygen content and fluidity, promoting cell activity, accelerating metabolism, and comprehensively improving the body's microcirculation.

3. Activating Water Molecule Biological Effect

Water molecules account for about 70% of human body weight, and cells account for about 40% of these water molecules. The binding state of water molecules has a significant impact on cell activity. Terahertz activates individual water molecules, reduces blood viscosity, enhances cell regeneration, boosts immunity, and achieves the effect of delaying aging.

4. Massaging Skin Cell Biological Effect

Terahertz activates high-frequency vibrations, which have a massaging effect on skin cells. This promotes the function of sweat glands, accelerates the excretion of waste within the body, unblocks pores, reduces keratinization, makes the skin smooth and delicate, reduces wrinkles, and achieves the effect of skin beautification.

5. Warming Biological Effect

Terahertz irradiation on the skin increases the temperature of subcutaneous tissues, dilates blood vessels, accelerates blood flow, and improves blood oxygen content. It promotes blood circulation, enhances metabolism, speeds up nutrient absorption, and accelerates the decomposition of metabolic waste, fat, free radicals, etc. within the body. The activated water molecules help expel toxins from the body, enhance mental vitality, and have excellent health care and adjunctive therapeutic effects.

Terahertz History

In the early stages, Tera Hertz (THz) was known by different names in various fields. In optics, it was referred to as far-infrared, while in electronics, it was called sub-millimeter waves, ultra-microwaves, and so forth. Prior to the mid-1980s, the development of infrared and microwave technologies on either side of the THz band was relatively mature. However, understanding of the THz band itself remained very limited, leading to the formation of the so-called "THz Gap".

In 2004, the U.S. government recognized THz technology as one of the "Top Ten Technologies That Will Change the World". Japan, on January 8, 2005, placed THz technology at the top of its "Ten Key Strategic National Goals", mobilizing the entire country for research and development.

In November 2005, the Chinese government specifically convened the "Xiangshan Science Conference", inviting multiple influential academicians in the field of THz research to discuss the development direction of China's THz endeavors and formulate a development plan for China's THz technology. Currently, several research institutions in China are conducting research related to the THz field. Among them, Capital Normal University is one of the early starters with significant investments. It has made many groundbreaking contributions in the THz spectroscopy, imaging, and identification of drugs and explosives, as well as in the non-destructive testing of internal defects in non-polar aerospace materials using THz. Due to the unique advantages of THz rays in security inspections, the THz Laboratory at Capital Normal University is concentrating on developing security prototype equipment that can be used for real-world testing. Additionally, governments, institutions, enterprises, universities, and research institutions in many countries and regions, including the United States, Europe, Asia, and Australia, have actively engaged in the THz research boom. Dr. Zhang Xicheng, a renowned American scholar and one of the pioneers in the field of THz research, exclaimed, "Nextray, T-Ray!"

Terahertz characteristics

1. Quantum energy and blackbody temperature are very low, as shown in Table 1.
2. The vibrational and rotational frequencies of many biological macromolecules lie within the THz band, so utilizing THz waves can yield abundant information about biological organisms and their materials.
3. THz radiation can penetrate substances such as ceramics, fats, carbon plates, fabrics, and plastics with minimal attenuation.
4. The signal-to-noise ratio of THz time-domain spectroscopy is very high, making THz highly suitable for imaging applications.
5. The instantaneous bandwidth is very wide (0.1 to 10 THz), which is beneficial for high-speed communication, as shown in the figure on the right.

THz-TDS

Currently, commercial operations have already begun, and several companies worldwide, mainly from China, the United States, Europe, and Japan, have started producing commercial THz time-domain spectrometers. The basic principle of THz time-domain spectroscopy is to generate and detect time-resolved THz electric fields using femtosecond pulses, and then obtain the spectral information of the measured object through Fourier transform. Since the vibrational and rotational energy levels of large molecules are mostly in the THz band, and large molecules, especially biological and chemical macromolecules, are groups of substances with inherent physical properties, it is possible to analyze and identify the structure and properties of substances through characteristic frequencies. One important application could be in pharmaceutical quality control. Imagine installing a THz time-domain spectrometer on the production line of a pharmaceutical factory. Every tablet produced by the factory undergoes spectral measurement and is compared with the spectrum of the standard drug. Qualified tablets proceed to the next stage, while defective tablets are removed from the production line, avoiding quality differences between different tablets or batches and ensuring the quality of the medication.
