Children with low fever and shivering is likely to be due to shock, cold and infection. 1. Suffer from shock: when the child is seriously frightened, the nervous system is overstimulated, causing dysfunction of the thermoregulatory center and sympathetic nerve excitation, which in turn causes vascular spasm and poor peripheral blood circulation, the child may have a low fever, chills, and shivering. 2. Cold and flu: If a child is cold, after being attacked by cold air, the body’s internal environment is disturbed, stimulating the immune system to open the self-protection mode, thus causing a low fever. When the body temperature of children with low fever is still rising, the body’s heat production is significantly greater than heat dissipation, which will make the child sympathetic nerve excitation, which in turn causes vasospasm, peripheral blood circulation is poor, the child can appear cold, shivering. 3. Infection: If there is an infection in the child’s body, the toxins produced by the pathogen will become endogenous pyrogen, leading to low fever. And because the body releases inflammatory mediators, stimulating the thermoregulatory center, can induce the chills reflex, thus appearing cold, shivering and other clinical manifestations. If a child has a low fever and chills and shivers, parents should pay attention and take the child to the hospital in time to find out the cause of the disease, and individualized treatment should be implemented by professional doctors.
