How does darling hand and nose very cool return a responsibility

First, because the metabolism of infants is more vigorous than that of adults, and the thermoregulatory center is not fully developed, the normal temperature of infants is higher than that of adults. However, there are some fluctuations in body temperature between day and night, low in the morning and high in the afternoon, but the fluctuation range is not more than 1 ℃.

Second: fever but cold hands and feet is a phenomenon of false cold and true heat, especially in infants under 3 years old. The main reason is that the blood volume of baby's limbs (especially infants) is less than that of the internal organs. Because of the insufficient blood supply of the limbs, it is easier to get cold than that of adults. In addition, the development of the baby's nervous system is not perfect, and the autonomic nervous system, which is responsible for the management of vasodilation and contraction, is prone to disorder, which leads to the spasmodic contraction of small blood vessels at the end of limbs and chills at the beginning of high fever.

Third: due to the immature development of children's central nervous system, the ability to regulate body temperature is not perfect. If the temperature of the surrounding environment is low, because the child's hands are exposed to the outside for more time, the hands and feet will be cold.
