Sharing a bed with someone could temporarily reduce your brain power - at least if you are a man - Austrian scientists suggest.
When men spend the night with a bed mate their sleep is disturbed, whether they make love or not, and this impairs their mental ability the next day.
The lack of sleep also increases a man's stress hormone levels.
According to the New Scientist study, women who share a bed fare better because they sleep more deeply.
Sleepless nights
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.
Sharing the bed space with someone who is making noises and who you have to fight with for the duvet is not sensible
Professor Neil Stanley, a sleep expert at the University of Surrey
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.
Both sexes had a more disturbed night's sleep when they shared their bed, Professor Kloesch told a meeting of the Forum of European Neuroscience.
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.
Their stress hormone levels and mental scores did not suffer to the same extent as the men.
But the women still reported that they had the best sleep when they were alone in bed.
Bed sharing also affected dream recall. Women remembered more after sleeping alone and men recalled best after sex.
Separate beds
Dr Neil Stanley, a sleep expert at the University of Surrey, said: "It's not surprising that people are disturbed by sleeping together.
"Historically, we have never been meant to sleep in the same bed as each other. It is a bizarre thing to do.
"Sleep is the most selfish thing you can do and it's vital for good physical and mental health.
"Sharing the bed space with someone who is making noises and who you have to fight with for the duvet is not sensible.
"If you are happy sleeping together that's great, but if not there is no shame in separate beds."
He said there was a suggestion that women are pre-programmed to cope better with broken sleep.
"A lot of life events that women have disturb sleep - bringing up children, the menopause and even the menstrual cycle," he explained.
But Dr Stanley added people did get used to sharing a bed.
"If they have shared their bed with their partner for a long time they miss them and that will disturb sleep."

If they were unmarried and sleeping together and willing to be research subjects they were already a little dim - I bet if they tested eight unmarried couples - with children- they would be even dimmer!
Oh come on guys...Obvious solution here....."get some before you go to sleep, & in the MORNING". 1. you will both sleep like a rock, and 2. There's not a one of you that can HONESTLY say that you aren't more alert after a quickie before work!
There is NOT a better way to start the day, especially if you get into the habit of it! Make this a "study" in your own homes and see how you do.......

This study is pretty accurate with me and my significant other. She sleeps better when we are together. I sleep better when I'm alone. She hogs the bed, steals the covers, changes her mind and pushes them off when it's cold, etc...

No good.you get "some" before, knock out at like 12ish. around 3 oclock u feel her body next to u and u cuddle, that turns into more touching, next thing u know ur sleep humping. at 3:30 u both wake up like "wth? oh wells, lets just roll with it" 4:20 u both go back to sleep. wake up at 8:00 like "oh ****! i'm late for work!" she turns her back to you and does the morning yawn thats so freakin sexy, u hug her and give her a kiss on the cheek, she turns around and kisses u back, and BAM! you get to work at 10:30. 2 and a half hours late, cloths dont match, hair not done, some funky white stains on the lower front part of ur tshirt that a co worker points out to u. in ur head ur thinking "oh man, should have just sleep with my back turned to her"
