Is heating insoles safe for human body? Heating insole is a common heating artifact in life. It is known that there are several electric heating wires in the heating insole, which generate heat by using the thermal effect of current after being electrified. There are many kinds of electric hot wires, which are called resistance wires in physics. According to different conductor materials, there are nickel-chromium alloy wire, constantan wire and carbon fiber. Resistance wire has the advantages of stable temperature rise, slow heat dissipation, safety and reliability, and will not cause fire due to local high temperature, so it is harmless to human body.
What's wrong with long-term use of heated insoles? What's wrong with long-term use of heated insoles? Many people will have questions when using this object. Although it is not harmful to the human body, I generally don't recommend using heated insoles, which is not good for the health. There are warm babies on the market and online now. It is an additional substance that can stick to the outside of socks, and can be kept warm for 12 hours or not. And the price of warm baby is very cheap. The harm to the human body is also small.
Heating insole 1 precautions for use. It is best to dry the insole before use, so that the insole can fully absorb the infrared rays in solar energy.
2. After putting it on, press it on the insole, take a walk and stand for one stop (about 15 minutes), and the insole will continue to keep warm.
3. Before and after each wear, it is best to wipe your feet with a wet towel to keep your feet moist and accelerate the temperature rise.
4, cleaning, only hand washing, do not use a shoe brush, do not machine wash, do not dry. Store in a dry and ventilated place.
5. Due to long-term use or improper maintenance, heat cannot be released. Please put the insole full of energy in the sun and expose it directly in order to recover.
