It may be better for your health to sleep in a separate bed than your partner—but a new study finds that the happiest couples are those who sleep close together. Very close together, as in less than an inch apart. A survey of 1,000 people found that those who kept such close parameters had an 86% chance of reporting they were satisfied in their relationship, compared to 66% for those who slept 30 inches apart or more, the Telegraph reports. Another predictor of relationship happiness: touch. While 94% of couples who made physical contact throughout the night reported a happy relationship, just 68% of couples who kept their distance did the same.
The survey also looked into how, exactly, the couples slept together: 42% back-to-back, 31% facing the same direction, and 4% face-to-face. The happiest positions? Well, according to the Independent, 91% of people who reported sleeping with their backs touching also reported a happy relationship, as did 91% of people who reported facing the same direction while touching (so, "spooning" would qualify). But if you've just always needed your personal space, no worries: "The key issue," says the lead researcher, "is if you have a couple who used to sleep close together but are now drifting further apart in bed, then that could symptomatic of them growing apart when they are awake."
