Does the warm baby patch have any side effects? Correct use is the key

Many people use heat-blocking patches in winter, which can keep warm very well, especially female friends. But do heat-blocking patches have any side effects? In fact, as long as you master the correct method, there are no side effects. Stick it on the outside of the underwear.

1. Whether there are any side effects based on the heating principle of the warm baby

The heating materials of the hot pack are mainly composed of iron powder, activated carbon, vermiculite, water, salt and other materials. The heating principle is that the iron powder naturally heats up and releases heat. Under normal circumstances, the oxidation of iron powder is relatively slow and heat cannot accumulate. Under the action of activated carbon powder, the contact area between iron powder and air increases, so the heat that we can feel is generated. Salt and water are also used to accelerate the oxidation of iron powder. This principle was first seen in traditional Chinese medicine therapy bags, which use iron powder and vinegar for therapy.

The inner bag used in the heating patch is a breathable film applied on a non-woven fabric. It uses PE as a carrier and uses a special process to form a unique microporous structure in the breathable film. These special structures densely distributed on the surface of the film can breathe like skin. Thereby, the heating material in the inner bag of the heating bag can be evenly and evenly adsorbed to the two surfaces of the inner bag. Forms a complete warm patch. The uniformity of the air permeability of the breathable membrane determines the stability of the product's heating temperature, holding time, etc.

2. Are there any side effects from the reaction principle of the warm baby? The reaction principle of the warm baby is to use the primary battery to accelerate the oxidation reaction and convert chemical energy into heat energy.

In order to keep the temperature longer, the product uses the mineral material vermiculite for insulation.

Because the product cannot react before use, the bag material must be very special, consisting of a raw material layer, a gelatin layer and a non-woven bag. Non-woven bags are made of microporous breathable film. It also has to have a regular airtight outer bag - the gelatin layer. When in use, remove the outer bag and expose the inner bag (non-woven bag) to the air, and the oxygen in the air enters through the breathable membrane. The time and temperature of heat release are controlled by the oxygen permeability rate of the breathable membrane. If the oxygen permeates too quickly, the heat will be released all at once, and there is a possibility of burning the skin. If the oxygen permeation is too slow, there will be no temperature. After use, it becomes a dark brown solid containing carbon powder, NaCl solid, Fe2O3 solid and salts containing magnesium and aluminum.

3. Strictly follow the instructions for using the heat pack to avoid side effects. 1. Stick it to the outside of the underwear, not directly on the skin (except for the skin patch type). 2. It is not suitable to use when sleeping at night to prevent low-temperature burns.

3. Avoid damaging or destroying the vacuum plastic packaging bag, otherwise the product will become ineffective. 4. If it accidentally comes into contact with eyes, rinse immediately with clean water and seek medical attention. If ingested, induce vomiting and seek medical attention immediately.

5. Warm baby is originally for medical use. As long as it is genuine, there will be no side effects. Don't buy the fake ones that cost a few cents. I heard that they use industrial iron powder. 6. Low-quality products cannot be used.

To sum up the above, from the heating principle and reaction principle of the hot pack, it is obvious that the hot pack itself has no side effects and is a convenient heating product. The key lies in how people use it and whether they buy regular products.
