Children shaking when they are angry may be caused by stress, imperfect development of the nervous system, calcium deficiency and other reasons. 1. Being in a state of stress: the adrenal hormones in the body are secreted rapidly when the child is extremely angry, which puts the body in a state of stress, leading to an increase in nerve and muscle excitability, and uncontrolled muscle shaking of the whole body. 2. Imperfect development of the nervous system: Due to the imperfect development of the nervous system, the brain can not fully control the nerves and muscles, when there is neuromuscular excitation, showing overreaction, resulting in generalized trembling. 3. Calcium deficiency: Calcium deficiency can lead to increased excitability of the nervous system, as long as a little bit of external stimulation, there can be a strong excitability, so that the whole body muscle shaking. Found that the child shivering when angry, parents should be patient teaching and observation, usually can eat more calcium-containing foods such as milk, etc., such as a longer period of time after the child’s performance is not relieved, you can consult a doctor.
