Why do children sometimes have hot hands and feet when they have a fever, and they have to understand it anyway, but sometimes they have cold hands and feet? Some parents call cold hands and feet "internal heat" and "external heat" when they have a fever. This is really the case Is that right?

How is child hand hot foot cool to return a responsibility

First, we should start from the mechanism of fever. Human beings are thermostatic animals. Under normal circumstances, the body's heat production and heat dissipation are in a state of balance, which can maintain our body temperature between 36 ℃ and 37 ℃. When the pathogen invades the child's body, the pathogen acts as an external heat source, and some inflammatory products produced by the body after fighting with the pathogen after invading the body affect the central temperature setting point. At this time, the body will think that the temperature of about 36.5 ℃ is abnormal, and that the temperature of 39 ℃ or higher is reasonable, so the whole body will be mobilized to increase the temperature Produce heat and reduce heat dissipation to achieve higher body temperature. One of the ways of body heat production is the movement of skeletal muscle, so we will see the situation of limb shaking and shivering. At the same time, in order to reduce heat dissipation, the body will contract peripheral blood vessels, and there will be cold hands and feet. At the same time, the body will be afraid of cold, and naturally hope to wear more clothes to alleviate the cold feeling. This is also the way to reduce heat dissipation, and the heat production is greater than that after heat dissipation At this time, the capillaries of the hands and feet dilate again, and the heat production is equal to the heat dissipation again, so we can feel the whole body of the child getting hot, including the hands, feet and palms of the child.

Second: when children's body temperature rises, their hands and feet are often cold. The faster their body temperature rises, the more obvious the phenomenon of cold hands and feet is. When their body temperature rises to the plateau stage, their hands and feet will become hot. The cool or hot hands and feet we see are just different periods of fever, and there is no other special meaning. It has nothing to do with the "internal heat" and "external heat" mentioned by some parents.

Third: at ordinary times, mothers should give their children a balanced, scientific and reasonable health. They can also choose appropriate and scientific s run f Feng * Jin Kang & children's amino acid nutrition, probiotics moisten the intestines, protect the health of the intestines and stomach, balance the internal environment of the body, enhance children's resistance, and promote the healthy development of various functions of the body. Appropriate supplement of children's amino acids is of great help to the growth and development Help.

matters needing attention

Children's amino acid drink is extracted from the natural silkworm chrysalis of "animal ginseng", which can fully guarantee the natural source and supplement 10 kinds of essential amino acids needed by children. It is characterized by hypoglycemia, high vitality, acid-base balance, pure nature and balanced nutritional value. According to the amino acid spectrum of breast milk, it is more conducive to the absorption of nutrients by children's body, The combination of probiotics and prebiotics in children's amino acid drinks is conducive to improving children's immunity and promoting the absorption of calcium, iron, zinc and other trace elements. Probiotics can promote gastrointestinal health, prevent or improve diarrhea, and are more conducive to the healthy growth of children.
