Can terahertz waves lower blood pressure Choosing the right one is the most important!

THz radar

In essence, this is also a form of imaging. Given the strong absorption of THz rays by moisture in the atmosphere, short-range radar represents a strength of THz technology. One highly anticipated application is through-wall radar and mine detection radar, which can also be used in search and rescue operations for victims in earthquake relief efforts, although these are still in the research and development stage. This is because materials such as walls and wood allow THz rays to pass through, whereas the human body, which contains a significant amount of water, does not. Therefore, it is possible to detect the distribution and activities of individuals inside a building through the walls, which can have a profound impact on counter-terrorism and anti-kidnapping efforts. Similarly, this technology can also be used to locate individuals beneath rubble. As for mine detection radar, it is based on the fact that mines are typically located on or near the surface of the ground, and dry soil allows THz rays to pass through. The mines will reflect the THz rays back, enabling the detection of the targets.

THz Astronomy

In the universe, a significant amount of matter emits THz electromagnetic waves. Numerous molecules such as carbon (C), water (H2O), carbon monoxide (CO), nitrogen (N2), and oxygen (O2) can be detected in the THz frequency band. Prior to the application of THz technology, some of these substances were completely undetectable, while others could only be detected at very high altitudes or on the surface of the moon.

THz Communication Technology

THz technology, when applied to communication, can achieve wireless transmission speeds of 10GB/s, particularly in satellite communication. In the near-vacuum state of outer space, where the influence of moisture is not a concern, this is several hundred to over a thousand times faster than current ultra-broadband technologies. This allows THz communication to conduct high-bandwidth and highly secure satellite communications. Although the lack of efficient THz transmitting antennas and sources currently prevents its commercialization in the communication sector, this challenge is bound to be addressed by the development of novel emitting devices and sources.

Terahertz radiation

German researchers, using supercomputers, have discovered that intense terahertz radiation can instantaneously boil a microscopic amount of water in less than a trillionth of a second.

Terahertz radiation refers to the electromagnetic radiation region with frequencies ranging from 0.1 terahertz to 10 terahertz, and wavelengths between millimeter waves and infrared rays. One terahertz is equal to one trillion hertz.

The Deutsches Elektronen-Synchrotron (DESY) research center in Germany reported that intense terahertz radiation can cause water molecules to vibrate violently, breaking the hydrogen bonds between them. This method can heat approximately one nanoliter (one billionth of a liter) of water to 600 degrees Celsius within half a picosecond (one picosecond is one trillionth of a second).

The report points out that although one nanoliter of water may sound insignificant, it is sufficient for many experiments. A picosecond is much faster than the blink of an eye, so this method of boiling water can be considered the fastest to date.

Although this "water boiling" method has not yet been put into practice, researchers suggest that water plays a crucial role in many chemical and biological processes, and this new discovery may provide more experimental possibilities for the fields of chemistry and biology.

What are the effects of terahertz waves on the human body？

1. Penetrating biological effect: Far-infrared terahertz waves can penetrate 3-5 centimeters into human skin, directly acting on deep tissues, replenishing energy for life cells, 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 micrometers of terahertz. When these wavelengths interact with 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 flow dynamics, promoting cell activity, accelerating metabolism, and comprehensively improving the microcirculation of the human body.

3. Biological effect of activating water molecules: Water molecules account for about 70% of human body weight, and cells account for about 40% of 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 ability, strengthens immunity, and achieves the effect of delaying aging.
