Students today are under great academic pressure, have close after-school interest classes, and spend long hours in contact with screens. Studies show that children spend more than half of their daily waking time sitting still. But in fact, long-term sitting will increase children's risk of cardiovascular and hypertension, and will affect cognitive development and academic performance. The so-called "long-term sitting" includes watching TV, computers, video games, doing homework, attending classes, eating and taking public transportation.
The above-mentioned effects of long-term sitting are just the tip of the iceberg. During the interviews , children mentioned that they would sometimes get cramps when they stood up after sitting for a whole day. The main cause is that the legs are often bent, which leads to poor blood circulation in the legs, which may cause leg cramps (Yuen Siu-man, family medicine specialist at Hong Kong Sanatorium and Hospital, 2016). In order to encourage students to move more, the first school in Hong Kong to cooperate with the Department of Sports Science of the Chinese University of Hong Kong to conduct an experiment and trial the use of lift desks. Students need to stand for 5 minutes in each class. Students said: in addition to being able to move around and not being so rigid sitting all day, they also think that standing is more energetic than sitting. The experiment of using lifting tables in schools was carried out in Australia a long time ago. Similar studies found that the BMI (body weight index) of primary school students using lifting tables decreased, their waist circumference was reduced by 2cm, and their cholesterol and blood pressure were lower.
Nowadays, parents have higher expectations for their children and hope that their children can win at the starting line. This results in children having less time for play and more time for study. In addition to academic performance and talents, parents need to pay more attention to their children's health. For example, you can reduce the children's extracurricular activities, go to the sports field to exercise together on holidays or in the evenings, or buy an ergonomic children's lift table and chair.
