From a study at the University of Vienna
Men drained by bed sharing
Scientists in Austria say sharing a bed with someone temporarily reduces men’s brain power.
When men spend the night with someone their sleep is disturbed, whether they make love or not, and this impairs their mental ability the next day.
According to the New Scientist study, women who share a bed fare better because they sleep more deeply.
Professor Gerhard Kloesch and colleagues at the University of Vienna studied eight unmarried, childless couples in their 20s.
Each couple was asked to spend 10 nights sleeping together and 10 apart while the scientists assessed their rest patterns with questionnaires and wrist activity monitors.
The next day the couples were asked to perform simple cognitive tests and had their stress hormone levels checked.
Although the men reported they had slept better with a partner, they fared worse in the tests, with their results suggesting they actually had more disturbed sleep.
But women apparently managed to sleep more deeply when they did eventually drop off, since they claimed to be more refreshed than their sleep time suggested.
Dr Neil Stanley, a sleep expert at the University of Surrey, said: “Historically, we have never been meant to sleep in the same bed as each other. It is a bizarre thing to do.
“Sharing the bed space with someone who is making noises and who you have to fight with for the duvet is not sensible.”
Obviously Spouse wasn’t part of the study. He snores too darn much for me to get any rest next to him.
Sweet dreams that leave all worries behind you
But in your dreams whatever they be
Dream a little dream of me
