Self-heating knee pads survey

In our lives, especially the middle-aged and elderly people, due to the lack of attention when they were young, the middle-aged and elderly people often have knee pain problems, which causes them a lot of trouble. Then a thing called self-heating knee pad appeared, which is very popular among the middle-aged and elderly people. Now we will introduce the product of self-heating knee pad in detail.

Automatic heating is both the biggest advantage and the biggest disadvantage of the self-heating knee pad. Especially in hot weather, self-heating knee pads are not very suitable. If you continue to heat them when they are not needed, it will cause sweat and water accumulation, which is bad for the joints. It is forbidden for people with high fever, bleeding tendency, temperature sensation disorder, or damaged skin at the wearing site. It is also forbidden for people with pacemakers. People with individual allergies should use it under the guidance of a doctor. The self-heating waist protector is a high-tech product made with tourmaline functional material as the core and combined with nano-biological functional materials. The self-heating waist protector has the dual effects of thermoelectric and piezoelectric, forming a resonance with the human body's magnetic field. And through the body's own energy, it can continuously release heat energy, negative ions, and far infrared to produce deep thermal effects. It can effectively improve blood circulation, promote metabolism, dredge meridians, dispel wind and dampness, relieve pain and cold, and enhance the body's disease resistance.

After opening it, I found that in addition to a few small magnetic pieces, there were also a few small black dots inside. Is it true that what makes the knee pads hot is not the magnetic disk but these small black dots as said on the Internet? The reporter put the cut knee pad lining on his arm and soon felt his arm was extremely hot. So are these black spots really spicy? The reporter tasted it and found it very spicy, just like eating a very spicy pepper. So, do these black spots really contain capsaicin?

By smelling and tasting, there is indeed a spicy taste, which can be preliminarily judged that there is capsaicin in the heating knee pads. "Zhang Cui, deputy chief physician of the Dermatology Department of Shijiazhuang Third Hospital, introduced that capsaicin can be both natural and synthetic. Since natural capsaicin and synthetic capsaicin are extremely similar, it is impossible to determine whether the capsaicin in this knee pad is natural. Natural capsaicin is extracted from pepper granules and is widely used in the pharmaceutical industry. It can affect nerve substance P and relieve pain, but it is not suitable for everyone. Natural capsaicin has side effects on patients with sensitive skin, redness and itching, and local blisters, and is not recommended. If there are patients with arthritis and people who do not feel feverish, capsaicin can be used, but it must be natural. In addition, since natural capsaicin is expensive, it is only widely used in medicine. In other industries, artificial capsaicin is mostly used.

Above we have introduced in detail what self-heating knee pads are, as well as its advantages and disadvantages. From the above introduction, we can know that anything external is not as good as what you already have, so young friends should take good care of their bodies and don’t do it when you are young. I hope the above introduction can help everyone.
