In general, newborns’ hands should not be wrapped. If the hands are wrapped up in summer or when the weather is warmer, it can cause increased sweating, which can lead to hand rashes, which can be detrimental to the growth and development of a child’s hands. If your newborn is in a cold season, such as winter or when you go out, you can wrap your newborn’s hands. This is because if there is cold stimulation, it will easily lead to frostbite on the newborn’s hands. Because the blood circulation of newborn babies is relatively poor, the resistance of blood is also weak, cold stimulation is easy to cause blood circulation is weakened, causing vasoconstriction thus leading to the occurrence of frostbite. Whether the newborn’s hands should be wrapped up, according to the cold or not, as well as the newborn’s mental state, physical state and other comprehensive consideration.
