Nutrition and sleep
Iron deficiency, zinc deficiency and calcium deficiency will all affect children's concentration. Excessive lead and insufficient sleep at night will also affect the cultivation of children's concentration.
Excessive stimulation of external environment
Taking part in too many interest classes is easy to make children feel tired of learning, and it is easy to have inattention when reading. If electronic products are used too early and excessively, it may be difficult for children to concentrate on the study of textbooks in the future.
