As much as sleeping together promotes togetherness, allowing for end of day discussion or pillow talk, some say it is not as great as advertised. There can be a lot of things that don’t work when sharing a bed, no matter how big it is.
An increasing number of couples are finding that separate beds or even separate bedrooms, solves many of these problems. There is still a stigma about not sharing a bed or bedroom in America. It is easy to understand when extraordinary circumstance, like severe illness or one of them traveling for work, prevents co-sleeping, but that is considered to be temporary or unusual. People are loathe to admit that they do not sleep together.
For aristocrats this has not always been the case. Not only did they often have their own beds, they often had their own suite of rooms or even their own wing of the estate. While this may have made “conjugal” visits more like date night, it may also have made affairs and dalliances easier too.
Orthodox Jews also have a tradition of sleeping in separate beds. The Law of Niddah requires that a husband and wife must not sleep in the same bed while she is menstruating. This separation begins at the first sight of blood and must continue until the end of the 7th day after bleeding has stopped. This actually encourages them to resume sexual conduct at a time when the wife is most likely to be fertile.
Unless there are specific religious or health reasons most people still prefer to sleep together. According to the Daily Mail people get more restful sleep and are less likely catch each other’s colds if they sleep apart. Still only about 8% of couples will admit to sleeping in separate beds. They quote Dr. Neil Stanley, “Intimacy is important for emotional health. But good sleep is important for physical, emotional and mental health.”
