Body warmer's heating materials are mainly reduced iron powder, activated carbon powder, salt and water. Because it is a chemical reaction to generate heat, no matter it is the raw material or the heating process, it is not harmful to the human body. However, when the skin is in contact with a heating body higher than body temperature for a long time, it is easy to cause warm burns, so be careful when using it.
The main raw materials of Body warmer are reduced iron powder, activated carbon powder, salt and water. The heating principle is that the iron powder is naturally oxidized and emits heat. As we all know, in the natural state, the oxidation of iron powder is a very slow process. The heat released is quickly dissipated, and the use of activated carbon can increase the contact area of iron powder with the air, and salt and water can accelerate the oxidation process, thereby releasing the heat within 12 hours.
From this, it can be seen that neither the raw material of the Body warmer nor the heating process is harmful to the human body, but when the skin is in contact with a heating body higher than body temperature for a long time, it will destroy the symptoms such as erythema and blisters caused by the soft tissue. Therefore, using the Body warmer for a long time can easily cause low temperature burns, so it must be attached to the outside of the spring and autumn clothes when using it, and stop using it immediately when you feel uncomfortable. Therefore, the side effect of Body warmer is that it may cause low temperature burns.
In addition, Body warmer is not suitable for everyone, pregnant women and children should try to avoid using it. If the user's skin is particularly sensitive, they should be careful not to overheat when using it, and do not stick it directly on the skin. Do not use it at bedtime or at the same time as heating equipment. When used in bed or at the same time as heating equipment, the temperature of the Body warmer will rise and cause low temperature burns.
Where can body warmers be used? Generally speaking, the use positions of Body warmer mainly include the following:
1. Below the belly button
The stomach area is very large, which is very suitable for body warmer. And there are many blood vessels there, which are easier to absorb heat than others. If the Body warmer is attached here, it can slowly start to warm in the shortest time, and this position can especially protect the uterus, the vital organ of women, especially women who often cause unstable contractions due to cold during their menstrual period. Body warmer can soothe the physiology. It brings all kinds of discomfort during the period. Remember that those women who are particularly afraid of cold must remember to keep warm.
2. The sole of the foot
We can often see some students in Japanese variety shows or news. Even though the weather is very cold, they still wear very little. In fact, they already have measures to prevent cold. It is said that the cold starts from the feet, and sticking the Body warmer to the soles of the feet will definitely make people very comfortable.
3. Waist
There are many meridians in the human body, and the most famous acupoint is the Shenyue acupoint. The Shenyu point is located in the middle of the back waist, the specific position is 1.5 inches next to the spinous process of the second lumbar vertebra, sticking the Body warmer there can ensure the warmth of the middle part, and can also treat low back pain and spinal discomfort. If you can keep the temperature around this acupoint, it will help the blood to flow smoothly and improve the deficiency of cold. When you feel uncomfortable in the front of your stomach, the same is true for the waist.
4. Knee
There is a Zusanli point on the outer side of the knee, and a body warmer can be used to warm the lower body.
