Last Updated: October 25, 2021

Side-sleeping is the most popular sleeping position for adults, and there are many benefits associated with sleeping in this position. However, as with back and stomach sleeping, this position places particular demands on the body.

The best pillow for side sleepers is one that will provide the perfect balance between support and necessary cushioning to keep the head, neck, and spine correctly aligned. An incorrect pillow may lead to neck and shoulder pain and many nights of restless sleeping. It is essential to do your research to suit your personal needs and preferences.

Benefits Of Side Sleeping

Not only is side sleeping the most popular sleep position for adults✓, but it is thought to have the most overall health benefits. For example, studies✓ show that side sleeping can reduce heartburn/acid reflux and obstructive sleep apnea (OSA) that can lead to snoring. In addition, side sleeping can promote optimal spinal alignment and may help those with back pain. Second to lying flat on your back, side sleeping with the legs straight is believed to be the best sleeping position for your neck and back.

Benefits Of Side Sleeping

Side Sleeper Pillow: Considerations

In addition to using a mattress best suited for this sleep position, it’s important to choose the best pillow for side sleepers. Keeping the head aligned with the spine is key - essentially filling the gap between the bed and your neck. Like back sleepers, not all pillows may support the higher curve of the neck when sleeping on your side. The following factors are worth taking into consideration and will hopefully guide you in making the best purchase.

Side sleeper pillow considerations

Loft

Loft refers to the height of a pillow when your head is resting on it and is most likely the most important consideration for side sleeping. The best pillow for side sleepers is usually one with a medium to high loft that provides sufficient cushioning. Pillows that are either too low or too high can interfere with spinal alignment, lead to pressure in certain areas, and result in discomfort or pain. An easy check is to see if your head is at an angle to your spine when lying down. If so, your spine is not correctly aligned. If your needs or preferences change, a pillow with an adjustable loft could be a good idea.

Firmness

A pillow that feels too soft may cause too much sinking of the head, and one that is too firm may cause discomfort. Both, as with the loft, can potentially result in incorrect spinal alignment and pressure points. Therefore, a pillow of medium firmness that provides a balance of contouring and support is most usually adequate for side sleepers.

Materials

The materials used to construct a pillow’s cover and filling can impact several important factors. For example, certain fill materials may compress more over time whilst others are better at maintaining shape. In addition, some fill and cover materials are more efficient at temperature regulation (similar characteristics to cooling pillows). And some may have special hypoallergenic or antibacterial qualities that may or may not be necessary for you.

Price

The price will depend largely on the materials used to construct the pillow. You will generally pay more for higher quality materials or any advanced technologies or design used; however, you can most likely rely on them having a longer lifespan.

Side Sleeper Pillow: Materials

The type of pillow and pillow fill often comes down to personal preference. Certain materials have specific qualities that can offer you the optimal combination of comfort and support, as well as other benefits.

Side sleeper pillow materials
  • Hollow fibre: Hollow fibre is made using fine, hollow strands of polyester. These hollow fibres trap air inside them, and this material is therefore known to be lofty, lightweight, soft and breathable. Additionally, hollow fibre tends to be cheaper than other materials, such as foam.
  • Memory foam: Memory foam contours to the exact shape of the head, relieving pressure, distributing weight evenly, and providing cushioning and support. Memory foam pillows are hypoallergenic, hygienic, inexpensive and durable. In addition, they retain their shape over time. They are, however, known to retain heat may therefore not be ideal for hot sleepers.
  • Feather: Duck feather pillowsgoose down pillows, and feather imitation pillows tend to be soft and conform excellently to the shape of the head and neck, have the potential to last a long time, and can be reasonably priced. The downside is that they tend to lose their support and loft over time, feather quills may poke, and they may have an odour unpleasant for some.

Side Sleeping And Shoulder Pain

The shoulder is one of the largest, most movable, and complex joints in the human body. It is made up of the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). The shoulder joint has a wide range of motion, therefore, making it more vulnerable to injury. This, in turn, unsurprisingly, relates to published data that shows✓ the prevalence of shoulder pain in the UK population at an estimated 7%. 

Side sleeping and shoulder pain

Sleep disturbance and poor sleep quality resulting from shoulder pain due to many different shoulder conditions are well recognised. Although the causes of shoulder pain vary widely, the most causes of shoulder pain at night, according to the Cleveland Health Clinic, are:

  • Rotator cuff injuries: Overuse of the rotator cuff can result in tendonitis, strains, and tears of the tendons.
  • Rotator cuff tears: Tears of the rotator cuff can happen as a result of an accident (fall) or happen over time as a result of a repeated motion.
  • Osteoarthritis: As a result of cartilage degrading over time.

Whilst the causes and severity vary greatly, shoulder pain from side sleeping, whether it’s the cause or aggravating an existing issue, can be avoided or minimised using the best pillow for side sleepers. If your pain is not localised to the shoulder, specifically, it may be worth looking into pillows for neck pain or perhaps orthopaedic pillows. Please note, however, that pillows for side sleepers, or any pillow, should not be used as a diagnosis or treatment for a medical condition - always consult with your doctor first.

Side Sleeping And Wrinkles

Although sleeping on your side has been shown to have certain benefits, side sleeping can potentially cause wrinkles. However, it is worth noting that there does seem to be some inconsistency on this subject. Some doctors believe that sleeping in a position that causes the skin to fold causes wrinkles. Others believe sleeping in a particular position won’t significantly contribute to wrinkles. Either way, let’s look at how these wrinkles may come about.

Side sleeping and wrinkles

There are two types of wrinkles, namely: dynamic and static. 

  • Dynamic wrinkles form as a result of muscle motion. Repeated facial expressions/habitual movements cause the skin in that area to stretch. When we’re young, the collagen and elastin in our skin allow it to return to its original position. However, over time the skin is less able to “bounce back”.
  • Static wrinkles are caused by gravity, the loss of fat and collagen, and the loss of the skin’s elasticity. These wrinkles develop with time, and at some point, everyone will have them. Sleep wrinkles are an example of static lines caused by repeated mechanical compression of the face against the pillow. When we’re younger, the lines can smooth out during the day, but the lines deepen and become permanent due to the loss of collagen and elasticity with ageing. These lines can be visible on the face, neck, and cleavage.

Interesting to note!
Sleep wrinkles differ from expression wrinkles✓ in the mechanism of origin, location and direction - expression lines tend to be more horizontal or diagonal, whilst sleep lines are usually more horizontal.

The Solution To Sleep Wrinkles

Whilst sleeping on your back seems like the obvious solution, if this is not possible, here are a few things that may help reduce sleep wrinkles:

  1. Upgrade your pillowcase: a silk pillowcase could be a good option.
  2. Retinol: Retinols help to boost the production of collagen and elastin in the skin.
  3. Night creams: Creams containing hyaluronic acid can promote skin firmness and elasticity.
  4. Sleep: The skin produces collagen when we sleep, so getting a good 7 hours every night may help minimise wrinkles.
