Why hugging a pillow helps some people fall asleep

Hugging a pillow helps some people fall asleep because it is comfortable and fixes a real problem for side sleepers. It gives the top arm somewhere to rest, keeps the shoulder from rolling forward, and makes rolling onto your stomach less likely. A long pillow can also sit between the knees, which may ease the lower back¹.

Comfort counts

Feeling comfortable in bed is not a small thing. The NHS lists an uncomfortable bed among the most common causes of insomnia, alongside stress, noise and a room that is too hot or cold². If holding a pillow makes bed feel better, that is a good reason to do it.

We are careful here. You may read claims online that hugging a pillow changes hormones or reduces anxiety. We have not found strong research showing that for pillows, so we do not repeat those claims. What is clear is the physical effect on your position.

What it does for your shoulder

On your side, the top arm has nothing to rest on. It falls forward across your chest, pulling the shoulder blade around and folding the front of the shoulder. Over a night, that can leave the shoulder or upper back sore.

A pillow hugged at chest height holds the arm roughly level with the shoulder. The shoulder blade stays back, and the joint sits in a more neutral position. Our guide to why your shoulder hurts when you sleep on your side covers this in detail.

What it does for staying on your side

Most people shift position many times a night. A pillow in front of you acts as a soft barrier: rolling forward onto your stomach means rolling over it. Many people find that once they hug a pillow, they wake on their side far more often.

That matters if you are trying to stop stomach sleeping, which twists the neck for hours. The Sleep Foundation notes side sleeping can help relieve some pain and reduce snoring⁴.

Three types of pillow to hug

A spare bed pillow is the easiest way to find out whether you like hugging. If you do, a longer pillow adds knee support and stays in your arms better. Our body pillow buying guide compares shapes.

A five step setup

1. Lie on your side with knees slightly bent. 2. Bring the lower shoulder slightly forward so you rest on the shoulder blade. 3. Hold the pillow in front of your chest so your top elbow sits about level with your shoulder. 4. If the pillow is long enough, let the bottom end run between your knees. 5. Check your head pillow fills the gap between neck and shoulder, as the Sleep Foundation suggests¹.

If your top arm still drops, the pillow is too thin at the chest. Fold it, or choose a fuller one.

How full should it be

Thin pillows let the arm sink, which defeats the point. The chest section needs enough body to hold your elbow up. Broad shoulders need a thicker pillow than narrow shoulders.

Pillows with adjustable fill let you add more to the chest section. Our guide to memory foam vs polyester body pillows explains which fills hold their shape under an arm all night.

Sharing a bed

A pillow in your arms takes space. Couples who sleep back to back often each use one. If you face your partner, a long pillow between you can feel like a wall, so a shorter one may suit better.

Check the width of your side of the bed before buying a large pillow. Our guide to what size body pillow you need has a bed size table.

Building a calmer bedtime

A pillow is one part of a comfortable bed. The Sleep Foundation suggests budgeting about 30 minutes to wind down before bed, dimming the lights, and keeping a consistent sleep schedule³. It also notes that sleep hygiene alone will not cure sleep problems³.

• Keep the room cool, dark and quiet.
• Put the pillow in the same place each night so you can find it in the dark.
• Wash the cover regularly, so it feels fresh.

When you are away from home

Hugging is a habit, and habits follow you. In a hotel, fold a spare pillow lengthwise and hold it the same way. On a long trip, a short travel body pillow keeps the same setup, so the first night away feels less strange. Some people find a familiar pillow in a new place helps them settle, much like bringing their own pillowcase.

When it is more than comfort

If you cannot sleep most nights for weeks, a pillow will not fix it. The NHS says insomnia usually gets better by changing sleeping habits². If changes have not helped after a few weeks and tiredness is affecting your days, speak to a GP.

Our pillows

The Cove Pregnancy Pillow is a 52 inch crescent: the middle is full enough to hug, and one tip reaches between the knees. The Cove Pregnancy Pillow Mini is the same shape at 36 inches, good for the sofa or a smaller frame. Both have adjustable shredded memory foam fill and a 100 night trial.
