Love shown in the way we sleep?Comment on this story
London - Are you someone who likes to cuddle up against your partner at night? Or do you tend to wake on the other side of the bed, facing the wall?
New research shows that the position in which we sleep is highly revealing about the strength of our relationships.
The key is the distance between couples, according to a study of 1 100 people.
Partners who sleep less than an inch apart are far more likely to be happy together than those maintaining a gap wider than 30 inches, the researchers found.
And couples who spend the night making physical contact are happier than those who do not touch.
The research, published at the Edinburgh International Science Festival, expands on work by psychiatrist Samuel Dunkell.
He found people who lie curled up in the “full foetal” position are likely to be indecisive, anxious and sensitive to criticism.
Those who sleep in a “semi-foetal” position, with their knees drawn up, are conciliatory, amenable to compromise, and unlikely to take extreme stances, he said.
People who sleep in the ‘royal’ position – flat on their back – tend to be confident, open, expansive, and sensation-seeking.
And those who lie “prone” on their face show a tendency for rigidity and perfectionism.
The new study found that 42 percent of couples sleep back to back, 31 percent face the same direction and just four percent face one another.
Around 34 percent sleep touching and 12 percent spend the night less than an inch apart, while two percent are separated by more than 30 inches.
Of those who fall asleep touching, couples tend to be happier if they are face-to-face than if they “spoon” their partners, facing the same direction, or if they face in opposite directions.
Of those who do not touch, the largest number of happy couples face the same direction – above those who sleep back to back or facing each other.
University of Hertfordshire psychologist Professor Richard Wiseman, who led the study, said: “Ninety four percent of couples who spent the night in contact with one another were happy with their relationship, compared to just 68 percent of those that didn’t touch.
“This is the first survey to examine couples’ sleeping positions, and the results allow people to gain an insight into someone’s personality and relationship.”
The study found 86 percent of couples who slept less than an inch apart felt happy in their relationship, compared with 66 percent of those who slept more than 30 inches apart.
The latest results are part of Professor Wiseman’s wider research on sleep and dreaming. He is using Dr Dunkell’s ideas to examine the ways people relate to each other in their sleep.
His initial findings suggest that people who sleep very close to their partners are more likely to be extroverts.
He has written a book, Night School, about his work.
Professor Wiseman said: “Thirty four percent of people said they slept touching, but this rose to 45 percent among extroverts.” - Daily Mail
