"Scientists believe the position in which a person goes to sleep provides an important clue about the kind of person they are. Professor Chris Idzikowski, director of the UK Sleep Assessment and Advisory Service analysed six common sleeping positions – and found that each is linked to a particular personality type"
Professor Idzikowski also examined the effect of various sleeping positions on health. He concluded that the freefall position was good for digestion, while the starfish and soldier positions were more likely to lead to snoring and a bad night’s sleep. Professor Idzikowski said "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. "Both these postures may not necessarily awaken the sleeper but could cause a less refreshing night’s sleep."
