Shivering and shivering in infants may be caused by vitamin D deficiency, high fever, epilepsy and other reasons. 1. Vitamin D deficiency: When blood calcium is lowered due to vitamin D deficiency, tetany may occur frequently, leading to shivering and shivering in infants. 2. Hyperthermia: in the early stage of fever, the body temperature rising stage may appear on the body heat, while the hands and feet are cold, shivering and shivering all over the body. 3. Epilepsy: The main symptoms are straightening of the eyes, convulsions or spasms of the body, bruising of the face, foaming at the mouth and so on. Infantile trembling and shivering can occur. Parents are advised to take their children to regular hospitals in time to clarify the cause and standardize the treatment under the guidance of the doctor, so as not to bring adverse effects to the body due to the delayed condition.
