A study in 2011 found that sleeping on the left side of the bed makes you more cheerful and positive.
A study of 3000 adults found that those who tended to sleep on their left sides were generally more positive
The study also found that 25% of left-side sleepers had a very positive outlook on life, as compared to 18% of right-side sleepers.
One consolation for right-side sleepers is that they tended to earn more than lefties.

Claire Haigh a spokeswoman for Premier Inn, who commissioned the research, said: ‘The research clearly indicates a pattern between which side of the bed you sleep on and the mood you wake up in.
‘Left sleepers are more cheerful, appear to enjoy life slightly more and have a more positive attitude to the day ahead than right sleepers.
‘It comes down to habit and what you’re used to. If you are used to sleeping on a certain side of the bed, it does feel a little alien when you switch.
‘So it seems the age old saying about getting out of bed on the wrong side is completely true.’
