A recent survey shows that the health of the students in our school has been going from bad to worse in the past three years. The number of short-sighted students has increased from 77% in 2010 to 93.5% in 2013, while that of overweight students from 38% to 57.2%. Nearly 15% more students don’t have enough sleep because of more homework. Besides, over 21% more students become mentally unhealthy.
It seems to me that the reasons for this lie in heavier burden of study and more homework, thus making students unable to spare any time to take exercise or have enough sleep. To improve students’ health, we call for less homework. Only in this way can students get plenty of sleep and be more healthy. Proper diets and exercise should also be paid attention to so that they won’t easily put on weight. With their heavy burdens removed, students can then keep in normal mental health.
