A child’s sleep shivering may be related to cold, light sleep, calcium deficiency, fever and other factors. 1. Cold: If the temperature of the environment is low when the child sleeps, or if the child does not take good measures to keep warm, it is easy to cause the child to have cold shivering and shivering during sleep. 2. Light sleep: If the child is a light sleeper, the slightest sound from the outside world will easily affect the child, which will also cause the child to sleep with a shiver. 3. Calcium deficiency: If the child lacks calcium or vitamin D, it will easily cause the excitation of the nerves and the brain, which will lead to shaking in the child’s sleep. 4. Fever: When the baby has a fever, it can also cause the body to twitch, so you should pay close attention to your child’s temperature or any other symptoms. As you can see, there are many reasons for children to shake in their sleep, and you should pay close attention to your child’s symptoms so that you can seek medical attention in time.
