When school starts after the holiday, primary and secondary school students show obvious non-organic pathological manifestations that are not suitable for the study and life of the new semester. Psychologists call it "school-starting syndrome" and "school-starting phobia"

School-starting syndrome has many manifestations, mostly manifested in physiology: insomnia, lethargy and some unexplained dizziness, nausea, abdominal pain, incontinence, fatigue, loss of appetite and so on. Psychological manifestations are: memory loss, decreased understanding, weariness of learning, anxiety, absent-mindedness in class, emotional instability and so on.
