Question
Why do infants often experience trembling in their hands during sleep, looking very restless? What are the causes of this condition and how is it treated?
Answer
According to the parents’ description, trembling in the hands during sleep in infants may be due to a deficiency of calcium or zinc in the body. A lack of calcium can increase the excitability of the brain and autonomic nervous system, thus affecting the quality of the infant’s sleep. It is recommended to supplement calcium and vitamin D promptly to improve the infant’s sleep problems. At the same time, if the infant shows symptoms of calcium deficiency, such as an unclosed fontanelle, or symptoms of zinc deficiency, such as ulcers around the mouth, they should also be supplemented with relevant nutrients accordingly.
