The part of the human body that comes into direct contact with the pillow is the cervical vertebrae, which are closely related to the shoulder, back, and waist muscles, ligaments, intervertebral discs, etc. This shows the impact that a suitable pillow can have on human health. The cervical vertebrae have a forward convex arc, known as the physiological anterior convexity. Removing dampness and strengthening the spleen are popular topics for women and middle-aged to elderly people in winter. In any situation, people find it most comfortable to maintain this natural physiological curve. Even during sleep, the normal physiological anterior convexity of the cervical vertebrae should be maintained to meet the physiological requirements. The function of a pillow is to support the head and neck while sleeping so that the cervical vertebrae can maintain their normal physiological curve even when sleeping. This allows the skin, muscles, ligaments, intervertebral discs, intervertebral joints, trachea, esophagus, nerves, and other tissues and organs in the neck to relax and rest together with the whole body.
Not only should the pillow properly support the forward convexity of the neck, but it should also accommodate the backward convexity of the occipital part (back of the head), because the occipital part protrudes backward. Only then will all the tissues and organs in the neck be in a relaxed and resting state. An unsuitable pillow or incorrect sleeping posture may cause excessive tension in the neck ligaments and muscles, accelerating the degeneration of the intervertebral joints and leading to functional disorders.
Choose the filling material type that suits you best. When sleeping, the pillow almost comes into close contact with the person, so the quality of the pillow's filling material has a great impact on our health. There are many types of pillow fillings, and understanding the advantages and disadvantages of each type clearly will help choose the most suitable pillow according to personal conditions.
Natural and environmentally friendly natural filling materials: Compared to synthetic chemical fibers, some people prefer pillows filled with natural materials, especially older people who tend to favor this type of pillow.
Buckwheat hulls - These are the most common pillow fillings, with moderate softness and hardness, good shaping and water absorption properties, and they are relatively light. The downside is poor elasticity, and the pillow makes noise when the head and neck move, which may affect sleep for those prone to insomnia.
Rice husks - Better shaping and water absorption than buckwheat hulls, but slightly heavier, and there will also be noise when moving.
Rice bran hulls - Have certain shaping properties, but their sharp edges can easily pierce fabric and irritate the skin, and they also tend to make noise.
Feather down - Feather down fibers have excellent rebound performance and temperature and humidity regulation functions, high breathability, providing a dry and comfortable "micro-environment" for the body. Feather down pillows cannot be washed with water, and people with allergies should avoid using this type of pillow to prevent respiratory discomfort.
Man-made filling materials with their own characteristics: Many high-quality man-made filling materials perform just as well as natural ones in terms of warmth retention, moisture absorption, rebound performance, etc., and some even have good antibacterial and anti-mold properties due to the nature of the material or additives.
Ordinary man-made fibers that are easy to clean - Made from chemical fiber cotton floss, they are convenient to wash with water and can even be washed in a washing machine. They can also be compressed and stored with vacuum compression bags, and they are inexpensive. However, chemical fiber cotton floss is not very breathable, and after long use, it tends to form lumps, losing elasticity and shortening its lifespan.
Hollow fibers with high technological content - Hollow fibers are the product of high technology, a composite material with one or more channels running through the otherwise poorly breathable ordinary man-made fibers, allowing each fiber to store more air. Pillows made with this filling material significantly improve in rebound, warmth retention, fluffiness, and lifespan. Due to differences in material and additives, some also have health care and medical functions.
Latex filling materials suitable for allergy sufferers - Latex is a filling material made by the "foaming" process using natural rubber. Since it is derived from purely natural materials, it is non-toxic, odorless, and has no adverse effects on the human body. The solid construction of latex eliminates interference from fine fibers, making it particularly suitable for people with allergies and asthma patients. Additionally, latex has good breathability, does not deform easily, and is easy to shape, providing appropriate support for the cervical vertebrae. However, due to raw material factors, latex pillows are relatively expensive.
