考试是最紧张的脑力劳动。在备考和应试期间,学生的高级神经活动明显增加,脑力消耗较大,心情过分紧张,睡眠不足,室外活动减少,再加上营养不够,很容易引起头痛、头晕,食欲不挂,体重减轻等症状。这不仅损害身心健康,而且学习效率下降,影响考试成绩,为此,考试前对学生加强考试卫生教育是十分必要的。 The exam is the most intense mental work. During the preparation and examination period, the students’ advanced neurological activities increased significantly, their brains consumed more, their moods were too nervous, their sleep was not enough, outdoor activities were reduced, and nutrition was not enough, which could easily cause headaches, dizziness, loss of appetite, weight loss, etc. symptom. This not only damages physical and mental health, but also decreases the efficiency of learning and affects the performance of examinations. For this reason, it is necessary to strengthen health education for students before the exam.
