In fact, at the beginning, they didn't sleep in that little bed, they all slept half-sitting, mainly for fear of choking their tongues. Moreover, Europeans generally believe that there is little difference between lying flat and dying, so they are more likely to be taken away by death and are willing to sit and sleep. In the previous era, the country was not particularly stable, so Peter the Great was very worried. He felt that sleeping in that big, soft bed was too comfortable, which made us sleep deeply, which was not conducive to preparing for the battle at any time.
Of course, it has something to do with religion, because in ancient Europe, all people believed in Catholicism, so among them, husband and wife slept in separate rooms, unlike us in China, so asceticism prevailed. It is for this reason that their beds are basically single beds, and they will think that a wide quilt is a symbol of depravity and desire.
Although we now see that Europeans live a very rich life, in fact, in ancient times, their lives were not particularly rich. They have worked hard every day since they opened their eyes. It is very cold in winter and there is no fire prevention in the house. Under such circumstances, it is definitely more comfortable to keep warm in winter. Although their living conditions have gradually improved, everyone has become accustomed to this way of sleeping.
