Objective To compare effects of the mental relaxation exercise along with wood music of five-element music and the mere mental relaxation exercise in removing study fatigue from students.Method Students from grade 6 were chosen as research object and were divided into experimental group and control group.38 students in the experimental group were trained with the mental relaxation exercise along with wood music of five-element music for two weeks while 32 students in the control group were trained with the mere mental relaxation exercise for two weeks.Coded scores of the two groups before and after training were tested and the results were statistically analyzed.Results The coded scores of two groups after training were higher than those before training and the differences were statistically significant（p<0.01）;there was no statistically significant difference in coded scores between the two groups before training;after training

coded scores of the experimental group were higher than the control group

and the differences were statistically significant（p<0.05）.Conclusion Setting-up mental relaxation exercise during the break has an obvious effect in removing study fatigue from students

and the psychological health-protection exercise during break along with five-element music is more effective in removing fatigue from students than the mere mental relaxation exercise.
