You may be mildly surprised to hear that Hollywood couple Helena Bonham Carter and Tim Burton sleep in separate houses, but we Brits aren’t too far behind them in our sleeping arrangements: a new study has found that ten per cent of British couples don’t share a double bed but have separate rooms! Of those who took part in a survey by esure, 22 per cent of couples have regular 'time out' from each other and 13 per cent of couples sleep in separate beds on one or more occasions each week. It's not just the bedroom that couples seem loathe to share: seven per cent have separate bathrooms while 12 per cent have gone as far as having a room which their other half is not allowed to spend time in! Interestingly, 39 per cent of those questioned said their relationship is healthier thanks to extra independence in their home life. Five per cent profess that the fact they and their partner have separate rooms is the key to their relationship happiness. The survey found that of all the age groups examined, the couples who were under 25 were most likely to sleep separately, with 21 per cent admitting to the arrangement.
