Key to a happier life? Sleep on the left-hand side of bed!

Want to know what's the key to a happier life? Snuggling up for the night on the left-hand side of the bed, so says a new study.

Researchers have found that people who sleep on the left-hand side of the bed are generally more cheerful and positive -- in fact, they lead a happier and a less stressful life, the 'Daily Express' reported.

In the study, based on a survey, a quarter of people said they had a bright outlook on life, compared to just 18 per cent of people who sleep on the right side of the bed.

They were also found to be better at tackling heavy workloads as well as stress. Two-thirds said they were calmer than their partner in a crisis. Meanwhile, those who sleep on the right hand-side tend to wake up in a bad mood more often.

People who favour the left of the bed also have more confidence and are more likely to be in permanent employment than those who prefer the other side. And while right-hand siders tend to earn more than their opposite numbers, those who sleep on the left are happiest at work.

In the survey, commissioned by hotel group Premier Inn, a third said they loved their jobs, compared to just 18 per cent of their right equivalents. One in 10 people who took to the right of the bed said they hated their work.
