Difficulty in falling asleep in a 10-year-old child may be related to calcium deficiency, diet and stress. 1. Calcium deficiency: When a child is deficient in calcium, it can cause higher nerve excitability, which can lead to difficulty in falling asleep, and it is necessary to consume more milk, shrimp, soy products to supplement calcium, or take vitamin D and calcium supplements. 2. Diet: If the child eats more food or drinks stimulating beverages such as coffee and strong tea before going to bed, it can also cause difficulty in falling asleep, so it is recommended to develop good bedtime habits. 3. Stress: 10-year-olds may have anxiety and stress due to academic pressure, family relationships, and social problems, so parents should communicate with their children in depth to find out if there is mental stress and channel it in time. There may be other reasons why a 10-year-old child may have trouble sleeping, so it is recommended to go to the hospital in time, complete the examination to determine the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
