Hazards of Self-heating Knee Pads

Nowadays young people are particularly fond of heating knee pads, because heating knee pads do not produce any electric current and there is no need to worry about any harm to the body. They are very safe and you will feel very warm when you buy them home and give them to the elderly at home. However, some people say that self-heating knee pads can be harmful and are particularly bad for the body. Therefore, everyone is very worried about whether they can use knee pads or how to choose them.

Tourmaline (commonly known as tourmaline)

What is this tourmaline self-heating waist protector? I bought 3 of them as gifts for my parents, but they are totally useless!

The small black spots on the white cloth of the belt are not tourmaline (commonly known as tourmaline), but rubber particles with some chemical capsaicin infiltrated into them. There is no such thing as nano-biomaterial, it is just rubber particles and a piece of cloth, and the cost is less than 1 yuan.

There is no continuous release of far-infrared, no microcurrent, and no spontaneous heating. If someone invents a substance that can produce these, he will definitely not make this thing to make money, because the Nobel Prize is waiting for him! This is the same scam as turning water into oil many years ago, and it violates basic principles of physics.

Natural capsaicin itself has certain medicinal value, but this is definitely chemically synthesized capsaicin, otherwise it would not be possible to integrate it into the rubber particles, and it would not be possible to have such a long-lasting spicy feeling. Chemical capsaicin has no medicinal value other than bringing a temporary spicy feeling. Moreover, long-term use of chemical substances will definitely decompose and become ineffective. The decomposed substances are very likely to be harmful to the human body, but because the amount is very small and the process is slow, the human body cannot detect it.
