Is it harmful to keep your baby warm often?

Generally harmless! But depending on how you use it, it belongs to that category.

Pregnant women: If the area is directly facing the uterus, it is likely to cause uterine contractions, resulting in fetal malformations and premature birth.

Baby: Baby** is very tender and has little activity to prevent low temperature burns.

People with diabetes and blood circulation disorders, ** people with low heat sensitivity, should pay attention when using it.

Stick it on the outside of underwear, not directly on the human body** (except for muscle patch type).

It should not be used when sleeping at night to prevent low temperature burns. (The maximum fever temperature for warming a baby is 63.)

There is no harm to the body in the warm baby patch, it is iron powder, activated carbon, inorganic salts, and water and oxygen in the air combined with heat.

After keeping warm, it will promote blood circulation, depending on whether the individual's physique is suitable for this, for example, some clear regulations are not recommended for diabetics, and others should listen to the doctor's advice if they are uncomfortable.

The reaction principle of the warm paste is to use the galvanic cell to accelerate the oxidation reaction and convert the chemical energy into heat energy. In order to keep the temperature longer, the mineral material vermiculite is used to keep warm. Because it cannot react before use, the bag material should be very special, consisting of a raw material layer, a gelatin layer and a non-woven bag.

The non-woven bag is made of microporous breathable membrane, and it also has to have a conventional non-breathable outer bag. When in use, remove the outer bag and let the inner bag (non-woven bag) be exposed to the air, and the oxygen in the air enters through the breathable membrane. The time and temperature of exothermia are controlled by the oxygen permeation rate of the membrane.

If the oxygen permeates too quickly, the heat will be released at once, and there is a possibility of burns**. If the oxygen permeates too slowly, there is no temperature. After use, it is a black-brown solid containing toner, NaCl solid, Fe2O3 solid, and salts containing magnesium and aluminum.

Is warming a baby bad for the body?

Warm baby is the principle of galvanic cells taught in high school chemistry.

Warm baby mainly uses toner, iron powder, water and salt water plus some additives to form a galvanic battery discharge, and then because there is no positive and negative electrodes, the electrons can not be divided into positive and negative electrons, directly forming a short circuit, resulting in heat.

When the vacuum bag is opened, it can gradually start to heat up, with a maximum temperature of 63 and an average of 53. The duration is 10 14 hours, and the duration depends on the amount added, generally about 12 hours of time is about 45 grams.

It is definitely harmless to the body, but if it is directly attached to the **, it is easy to be burned, so it is recommended to stick it to the outside of the underwear.
