A total of 783 elementary and middle school students in Beijing city and Shandong province were selected for a one-year follow-up investigation, and the impact of time length of using E-learning environment each week on physical health was explored from four aspects as eyesight, respiratory rate, body mass index, sit and reach. Through Covariance Analysis, we found that time length of using E-learning environment each week by elementary and middle school students had a significant impact on their eyesight, but not on the respiratory rate, body mass index, sit and reach. Meanwhile, the comparative results of elementary and middle school students between different genders and learning stages that affected by the time length of E-learning were basically consistent with the findings above. Slight difference was found that the E-learning environment produced significant impact on both left and right eyesight of elementary girls, but on the left eyesight of middle-school boys, and significant effect on the middle-school body mass index. Based on this, we proposed that the time length of E-learning each day for elementary and middle school students should be controlled less than 1.5 hours.
