Whether you like to curl up on your side or lie 'spread-eagle' across the bed on your back, experts believe the position you like to sleep in can reveal some telling signs.
Sleep expert, Professor Chris Idzikowskia, from the Sleep Assessment and Advisory Service, has found a direct correlation between sleeping positions and certain personality traits.
Identifying the most common sleep positions - the foetus, yearner, log, solider, starfish and freefall - Idzikowski also believes that the awkward sleep positions we get ourselves into, can have an impact on our health - both good and bad.
Foetus, log and yearner - "Invariably the side position is generally regarded as best for health, though advice going back to Greek times, or found in Yoga scripts is to lie on the right so that you're not putting pressure on the heart. However, some medieval texts suggested that half of sleep time should be spent on the right and the other half on the left."
Starfish and Soldier - "These poses involve sleeping on the back which tends to increase snoring and more serious problems with breathing, as well as stomach reflux and curiously with sleep paralysis (waking up in the morning paralysed and being unable to move for a few seconds)".
Freefall - "This position is best for digestion as lying down flat means that stomach contents can more readily be worked back up into the mouth, while those who lie on their back may end up snoring and breathing less well during the night."
Now, identify your sleep position from the descriptions below to find out if Professor Idzikowskia's personality analysis rings true.
