For those who dragged the covers off them this morning for a wet and windy first day back at work after the Christmas break, Premier Inn has now revealed that there is such a thing as the 'wrong side of the bed'. According to a new study carried out by the hotel chain, those who have a tendency to migrate to the left side of the bed are in fact far better off than their 'right' counterparts.

The study of 3,000 adults by the UK's biggest chain of hotels found that not only are those who sleep on the left generally more cheerful, but they are also more positive and capable of tackling heavy workloads and a stressful day ahead. Indeed, those who sleep on the right-hand side are less likely to wake up in a good mood. Over a quarter of people who snooze on the left side of the bed feel they have a really positive outlook on life in general, compared to 18% of right-side sleepers.

The upbeat morning mood of 'lefties' may also go as far as explaining why over half of those surveyed refuse to swap sides with their other half. In fact over 75% of Brits are so stuck in their sleeping routine that they would find it strange to sleep on the other side of the bed. Additionally, a quarter of them claim it would certainly affect their mood the next day, with 23% of the nation convinced there is a wrong side of the bed.

Claire Haigh, spokeswoman for Premier Inn who commissioned the research, commented: "The research clearly indicates a pattern between which side of the bed you sleep on and the mood you wake up in. At Premier Inn we guarantee a good night's sleep for all no matter what side of the bed they
sleep on. For those not satisfied with their stay, Premier Inn promises a full refund."
