Getting enough quality sleep is crucial for healing and preventing chronic neck pain. If you already have a history of neck pain, good sleep can also help lower the risk of a flare-up. One key factor in ensuring proper rest is choosing the right pillow for the cervical spine (neck). Let’s explore why this decision can be tricky and what you should keep in mind when shopping for a pillow.
Why Pillow Choice Matters
Researchers emphasize that the head and neck need proper support to reduce stress on the cervical spine, intervertebral disks, and nearby muscles in the neck, upper back, and shoulders. Many studies rely on what participants say about their experience, which can be subjective and may not always provide the most accurate data. However, some more objective research methods offer useful insights:
Pressure Measurements
One study used a pressure-sensitive mat with 1,024 sensors to measure how different pillow thicknesses affected pressure on the head, neck, chest, waist, and hips. The results showed that as pillow thickness increased, so did pressure on the neck and head.
Muscle Activity
Another study used electromyography (EMG) to measure muscle activity when participants slept on their side with pillows of various thicknesses. Pillows that were either too thin (5 cm) or too thick (14 cm) resulted in more muscle activity than a 10 cm pillow.
Spinal Alignment
Research also shows that a pillow with a height that’s too high or too low can disrupt spinal alignment, as confirmed by x-ray studies.
Materials and Shape
Material: A springy foam pillow that retains its shape may relieve neck pain better than a softer pillow that flattens overnight.
Shape: Pillows come in different shapes—rectangular, u-shaped, or b-shaped. The ideal shape depends on personal preferences and how you sleep (on your back or side).
The Challenge of Nighttime Movement
Sleep is not static. Throughout the night, people change positions about 24 times to relieve fatigue, often switching between lying on the back (supine) and the side (lateral). A pillow that feels perfect for back-sleeping might not be the best for side-sleeping. This creates a challenge: you need a pillow that can accommodate different sleep positions.
Looking to the Future
We may someday have pillows that adjust their thickness automatically based on our sleeping position. Until then, you’ll have to do your best to find a pillow that suits both your anatomy and your natural sleeping postures. Current research suggests:
A proper pillow height and the right firmness are key.
The shape of the pillow (rectangular, u-shaped, or b-shaped) can also make a difference.
Consulting a Professional
If you struggle with neck pain, consider consulting a chiropractor. They can offer personalized pillow recommendations based on your case history. Your chiropractor might even supply specialized pillows or help order the right one for you. With the right pillow—and plenty of restful sleep—you’ll be taking a big step toward relieving neck pain and promoting a healthier spine.
