Background

At present, middle school students are heavy in class industry, schools are far away from home, or parents are on duty, and no one can attend lunch, so that middle school students generally choose to have meals in school restaurants or schools to classrooms, but teenagers of middle school students in the growth stage are seriously lack of sleep, and are not in conflict. Many schools have no condition to provide a dormitory for noon break, students all lie on the desk for noon break, the posture of noon break is uncomfortable, and due to the fact that multiple nerves are compressed, anxiety is often caused during the noon break, and the sleep is not real; temporary blurred vision often occurs after afternoon nap because the eyeball is compressed. If the eye pressure is too high for a long time, the vision is damaged, eyeballs swell and the axis of the eyes grows over time, high myopia is formed, and the incidence rate of glaucoma is increased easily. People who have slight myopia symptoms, myopes or people wearing contact lenses are particularly careful not to take a hand for a long time to rest afternoon. The long-term compression on the arms and the face can affect the normal blood circulation and nerve conduction, so that the arms and the face feel numb and even feel sore. If left unattended, over time can evolve local nerve palsy or facial deformity, with the resulting sequelae sometimes even being lifelong. The bending down is also easy to cause spinal deformation, if the pillow is worn into school with sleep, the normal storage during class also is a problem, occupies a large amount of space, even if the school provides a storage cabinet, because sweat or even tap water can soak the sleep pillow during noon break, the soaked sleep pillow can not be fully aired and volatilized, bacteria are easily bred, and the health of students is influenced.

As students are easy to get too close to the desktop for long-term study, the distance cannot be effectively kept, and the eyesight of the students is not facilitated.

Therefore, a midday break scheme which is convenient for students to have a midday break and does not greatly increase the operation cost of schools is urgently designed.
