Sleep takes up about a quarter to a third of an adult's day. When we're fast asleep, the muscles in our neck, shoulders, and the whole body should be totally relaxed. But if you use a pillow with the wrong height for a long time, your cervical spine will stay in a bent or twisted position. The muscles in your neck and shoulders won't relax even when you're sleeping. When you wake up, the pain in your neck, shoulders, or lower back won't get better—maybe even worse.

Pillows are must - have sleep items, and they play a super important role in our lives. They support your neck, taking pressure off your cervical spine and preventing neck problems. They help relax the muscles in your head, neck, and shoulders, improving your sleep position and sleep quality. They also support your head, easing the burden on neck muscles and reducing tiredness. Good pillows keep your airways open for smooth breathing and reduce friction between your face and the sheets, protecting your facial skin. So, pillows are like a second partner in life, and picking the right one is really important.

Medically speaking, the spine has four natural curves: the cervical spine curves forward, the thoracic spine curves backward, the lumbar spine curves forward, and the sacral spine curves backward. The forward curve of the cervical spine is really important. It adds elasticity to the neck, keeps the cervical discs and joints under normal stress, and acts as a buffer. Many people with cervical problems start with the loss of this forward curve. So, keeping this curve is key to preventing cervical issues, and the first thing when choosing a pillow is that it should maintain this normal cervical curve.

First, pick the height based on your size. If you're petite, go for a pillow about 8 - 10 cm high. If you're between 165 cm and 175 cm tall, a 10 - 12 cm pillow is good. If you're over 175 cm, choose a 12 - 15 cm pillow.

Second, choose a pillow that fits your sleep position. Our bodies are most comfortable when standing naturally, so the pillow should match the spine's natural curves. If you sleep on your side, pick a taller, thicker pillow with some bounce. It keeps your cervical spine's natural curve and supports your head and neck well, so your cervical spine doesn't bend too much. If you sleep on your back, get a lower, soft pillow. It fits the shape of your head and neck, reducing cervical spine pressure. If you sleep on your stomach, it's better not to use a pillow or use a very low one. Sleeping on your stomach strains your cervical spine, and a pillow would bend your cervical spine too much, leading to problems like sleep apnea and neck - shoulder pain.

Also, think about other things. The pillow should be wider than your shoulders. Otherwise, when you roll over, the pillow can't support your neck. Small pillows also make you feel less secure when sleeping. For adults, a pillow should be 50 - 70 cm long and at least 30 cm wide. The pillow's material should be breathable to keep it dry and prevent bacteria and dust mites. The hardness and bounce should be just right—too hard or too soft isn't good. A medium - firm pillow supports your head and neck best.

 Consider your size, sleep position, and health needs. Also, change the pillowcase or pillow core regularly to keep it clean and effective.
