Waking up on the wrong side of the bed may be a matter of which side of the bed you tend to sleep on.
In this case, lefties have it best. Or, so suggests a British survey done for a hotel chain. The survey of 3,000 Brits found that those who sleep on the left side of the bed – from the perspective of lying in the bed, head on pillow – tend to be more optimistic, according to the Boston Globe.
Those sinister sleepers are more cheerful, more positive and capable of tackling heavy workloads and facing a stressful day ahead, Boston Globe writer Deborah Kotz reports.
"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 per cent of right-side sleepers," she writes.
It's hard not to immediately fact-check this study against your own experience.
Ms. Kotz calls the study "a bit of drivel," saying it's not true in her household.
More convincing, she says, is the finding that "three-quarters of the respondents were totally attached to the side of the bed they slept on to the extent that they needed to stick with that side when they travelled to get a good night's sleep."
Chatelaine writer Astrid Van Den Broek outs herself as a right-sider and says her husband is "by far the more optimistic half" of her relationship.
"Left-side sleepers were also reportedly calmer than their right partners in a crisis–definitely the case in our household," she writes.
Still, she points out that "happiness comes down to so much more than where in the bed you sleep. In fact, how much you sleep has a significant impact on how happy you are, as numerous studies have shown (and any sleep-deprived parent will tell you)."
Ms. Van Den Broek says she, for one, won't be swapping sides of the bed any time soon.
"Instead, I'm going to focus on other sleep-related ways to boost my happiness, namely keeping my phone out of my bed (no Twitter surfing!) and avoiding those ever-alluring late night Seinfeld reruns."
We're hoping to see a survey on that, soonest.
