There are many reasons for children to have cold hands and feet. Clinically, it is thought to be caused by the child’s less fatty layer, less fully developed blood vessels, as well as a relatively large body surface area and excessive heat dissipation, in addition to cold weather and too little clothing. Children’s bodies usually have brown fat, which is mainly responsible for maintaining body temperature during infancy, but as they grow older, the brown fat will gradually decrease, which can cause cold hands and feet if they are not kept warm. And children’s body surface area is larger, compared to the adult heat dissipation faster, so it is easier to appear cold hands and feet. Because of their young age, children’s body organs are not fully developed, and their capillaries and peripheral circulation are not fully developed, so when there is a circulation disorder, it is also easy to cause cold hands and feet. Children are sensitive to the outside temperature, and when autumn and winter come, if they do not increase their clothing in time, it will lead to cold hands and feet. You should prepare your child’s clothes for autumn and winter, and actively keep the face, neck, hands and feet warm, so that the symptoms of cold hands and feet will improve.
