According to Dr. Johnathan Halevy from Family Medical Practice infirmary, half of preschool students and 40 percent of Vietnamese adolescents sleep less than a normal sleep of 8 hours.
Most Vietnamese kids sleep less than six hours a night, shorter than a normal sleep of 8-10 hours a day. Main reasons of lack of sleep attribute to surfing on social network, online game playing and learning pressure.
