What is the most comfortable posture to sleep in class?

Summer and autumn clothes are very moderate, and sleeping on the table will not be too tired. 2

It is too hot in summer. I suggest you unbutton and stretch your hands and feet. More breathable. Your face will stick directly to the desktop. It will be cooler in summer. three

Wearing cold clothes in winter is even more bloated. Try to curl up when you sleep, so that the heat loss will be less. Better wear a hat. For reference only, please do not imitate. After all, it's too dangerous to sleep in class, so it's best to play with less difficult movements. First, respect the teacher.
