      Bed sharing 'drains men's brains'


      Bed sharing disturbed sleep quality

      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."
