Sleeping positions

Sleeping preferencesEdit

A Canadian survey found that 39% of respondents preferring the "log" position (lying on one's side with the arms down the side) and 28% preferring to sleep on their side with their legs bent.[1]

A Travelodge survey found that 50% of heterosexual British couples prefer sleeping back-to-back, either not touching (27%) or touching (23%). Spooning was next, with the man on the outside 20% of the time vs. 8% with the woman on the outside. 10% favored the "lovers' knot" (facing each other with legs intertwined), though all but 2% separated before going to sleep. The "Hollywood pose" of the woman with her head and arm on the man's chest was chosen by 4%.[2]

Health issuesEdit

In the 1958 edition of his best-selling book The Common Sense Book of Baby and Child Care, pediatrician Dr Benjamin Spock warned against placing a baby on its back, writing, "if [an infant] vomits, he's more likely to choke on the vomitus." However, later studies have shown that placing a young baby in a prone position increases the risk of sudden infant death syndrome (SIDS). A 2005 study concluded that "systematic review of preventable risk factors for SIDS from 1970 would have led to earlier recognition of the risks of sleeping on the front and might have prevented over 10,000 infant deaths in the UK and at least 50,000 in Europe, the USA, and Australasia."[3]

It is recommended that people at risk of obstructive sleep apnea sleep on their side[4] and with a 30° or higher elevation of the upper body.[5] Snoring, which may be (but is not necessarily) an indicator of obstructive sleep apnea, may also be alleviated by sleeping on one's side.[6]

Modern scientific studies have suggested a beneficial effect of the right lateral decubitus position on the heart. In particular, one study assessed the autonomic effect of three sleep positions (supine, left lateral decubitus, and right lateral decubitus) in healthy subjects using spectral heart rate variability analysis. The results indicated that cardiac vagal activity was greatest when subjects were in the right lateral decubitus position.[7]

IslamEdit

In Islamic culture, some sleep positions are encouraged while others are discouraged based on the practice (Sunnah) and recommendations of Muhammad. Thus, many Muslims sleep on their right side, particularly, in the initial part of sleep. Muhammad said, “Whenever you go to bed, perform ablution like that for the prayer, and lie on your right side” [SM 2710).[8]
