A study out of the University of Hertfordshire showed that 94 percent of couples that spent the night in contact with their partners were happy with their relationship. On the flip side, 68 percent of couples that slept the night on opposite sides of the bed showed the same feelings of happiness.
The same study found that couples that sleep touching face-to-face are far more content with their relationship than couples that sleep in the spoon position. But within the group of couples who sleep without contact, the group that slept facing the same direction was more content then the group that faced each other.
The research did not elaborate on what stage the relationships were at. From experience, we might assume that the close sleepers were probably at the initial stages of their time together.
Your comfort is important, but so is contact. Maintaining a physical bond with your partner will increase your endorphin levels and solidify your feelings for each other.
