Pros and Cons of Different Sleeping positions

Everyone loves a great night’s sleep, and we’ll usually spend up to a third of our lives lying down! Most of you will have a favourite position to sleep in, whether that’s on your side, your back, or face down on your tummy, most people will have a preferred sleeping position. But when something gets in the way, it’s important to know the pros and cons of each position so you can still rest up despite things like back/neck pain, sleep apnoea, snoring, or reflux! 

Supine – Lying on your back

This one is not too common, a 2007 study (Gordon, Grimmer & Trott) reported approximately 10-15% of people choose to sleep on their backs, but there are plenty of good things about this position!

An important process with sleeping, especially for those with aches and pains, is the unloading of our muscles, joints and connective tissues, and their refuelling and recovery over the night. These loads and pressures drop to 25% of what they are while standing, if we lie on our backs (Haex, 2004). This position is especially effective in unloading the spine as it allows for neutral alignment, where pressure is distributed more evenly. 

Furthermore, for those with reflux, assuming they’re using a pillow so their head is elevated, lying on their back is also helpful in reducing these symptoms while they sleep (Hamliton, Boisen, Yamamoto, Wagner, Reichelderfer, 1988)

Now, we should also note that sleeping on your back may not be as good for people who have sleep apnoea (trouble breathing while sleeping), which is often those who tend to snore. This is because of the position of the tongue, which may block your airways, making it harder to breathe (Lee, Kim, Kim, Rhee & Won, 2015).

Sidelying 

Moving on to the most popular sleeping position: lying on your side is commonly reported as being the preferred position of 40-50% of people but has been reported as high as 70% (Gordon, Grimmer & Trott, 2007). This can be from a foetal position – curled up into a ball – to a ‘log’ position, arms and legs straight, or anywhere in between. 

One huge benefit for side sleeping would be that it considerably reduces the risk of sleep apnoea (Lee et al., 2015). This is especially useful in comparison with sleeping on your back and can be paired with the advantage that improving symptoms of sleep apnoea can actually alleviate those of reflux (Shepherd et al., 2011). So, if you’re having trouble with breathing/snoring while sleeping on your back, and having some issues with digestion and reflux, sleeping on your side is a great alternative to try that could help both! 

Side sleeping is also important for pregnant women, with evidence showing issues with circulation for expecting mums sleeping on their backs. This can lead to a reduction in oxygen delivered to the foetus and has resulted in recommendations from the American Heart Association for pregnant women to try sleep on their left side if they have any heart or blood vessel issues. However, it is also acknowledged that people do move around while they sleep and its normal to lie on your back at times through the night (O’Brien & Warland, 2014). 

Finally, side sleeping also unloads the spine, but not to the degree of lying on your back. If you spend a lot of time with your spine in a curled/flexed position, for example sitting at a desk, sleeping in a foetal position can contribute to added volume in this position, which could cause your back to stiffen up. It would be worthwhile considering sleeping in a way that offsets this. So, if you prefer sleeping on your side, try straightening your legs out, rather than sleeping curled up (Haex, 2004).

Prone – lying face down 

Prone sleeping, or lying face down, is the least commonly chosen position for sleep, and it reduces with age, dropping to essentially 0 by 65 years of age, likely due to decreasing mobility with age and possibly the extra effort required to expand the rib cage for breathing (De Koninck, Lorrain & Gagnon, 1992)

Much like sidelying, sleeping in prone has been shown to reduce sleep apnoea and snoring compared with sleeping on your back (Bidarian-Moniri, Nilsson, Rasmusson, Attia & Ejnell, 2015). Other than this, there isn’t much research showing any benefits to lying face down, but it has been shown that a prone sleeping position is a significant risk factor related to SIDS (sudden infant death syndrome) and it is recommended that infants should NOT be put to sleep in a face down position (Task force on Sudden Infant Death Syndrome, 2011).

So which sleeping position is best for you?

So, what follows is a quick recap of the pros and cons of each position. Overall, barring medical conditions, sleeping position generally comes down to what’s comfortable for you. If you do have any of the above issues, or any other trouble sleeping, please be sure to consult your GP or a qualified health professional about these issues as well as what sleeping position may be ideal for you, your sleep is important!

  • Supine (on your back)
    • Pros: unloads spine, good for back pain; helps digestion and reflux
    • Cons: higher chance of snoring and sleep apnoea 
  • Sidelying 
    • Pros: Better for sleep apnoea, which can also improve reflux. Comfortable for most people/preferred sleeping position. Better for circulation in pregnant women. 
    • Cons: Not as good for spinal alignment and helping with back pain
  • Prone (face down)
    • Pros: Good for sleep apnoea 
    • Cons: higher risk of SIDS for infants, not as good for spinal alignment
