For many couples, bedtime is finally the time when they can get together, regroup and reconnect intimately with each other. Lots of couples love a little snuggle time at night, and researchers in Scotland are learning all that spooning may have an impact on the quality of the relationship. In a survey of 1,000 participants for the Edinburgh International Science Festival, researchers found that couples who slept less than 1 inch apart were more likely to be content with their relationships. In fact, 86 percent of those couples – who comprised 12 percent of the respondents -- reported being happy, while just 66 percent of participants who slept 30 inches apart or more reported being happy in their relationships. Physical touch during the night had an impact as well. While 94 percent of couples who did so reported a happy relationship, 68 percent of couples who kept their distance said the same.
