Tempting as it may be to turn over and hit your off switch post-sex, research from the University of Hertfordshire has shown that proximity to your partner when asleep has a significant effect on the success of your alliance.
Professor Richard Wiseman, the psychologist leading the study, found that 86 per cent of couples who slept just a couple of centimetres apart were happy with their lot, while 66 per cent of those who rolled their own way reported trouble a the mill.
Now that's not to say that the future of your relationship depends on a lifetime of spooning. Instead, you might just want to try putting old habits to bed and go cheek to cheek.
