Girls with long hair, please put your hair behind your head, it is not easy to poke your hair out of your cheeks and nose with one hand; The best way to support hands and legs is to let them find the most comfortable position by themselves, but don't affect each other's position. So are the legs. To put it bluntly, don't cling to each other and leave some comfortable space for each other.
Block the blown place. You can't sleep with your ears blowing on your neck. It's better to block it with a quilt or clothes. Cover your shoulders. A long time ago, I heard an old Chinese doctor say that people would feel uncomfortable if the shoulder well invaded the cold. When two people sleep, the quilt on their shoulders will inevitably be overhead, so leave more quilts to cover their shoulders.
Auxiliary items are also important. Especially when lying on your side, it is a good choice to find a plush toy or pillow to help balance your body, so that most of your weight will not be on the other person. If you feel uncomfortable, change your posture. When I was in a daze, I felt a crawling creature in my arms, which was quite cute. Adjusting the comfortable posture as soon as possible is good for both of them to fall asleep.
