To choose the right pillow, we must first understand the correct pillow method. The pillow is actually the neck of the pillow. It should be the neck that rests between the back of the head and the shoulders, which supports the neck during deep sleep. When lying on your back, the highest point of the pillow should be in the middle of the back of the neck to support the neck curvature and maintain the physiological curvature of the neck. The lowest point of the pillow is the back of the head. When lying on your side, the pillow supports your neck. It is possible to keep the spine in a straight line when viewed from the front and normal S-shape (in line with the physiological curve) when viewed from the side.
The health-care pillow is more in line with the physiological curve of the human body in its “high front and low back” shape, and the pillow fits well with the cervical spine during sleep. It supports the cervical spine and is more suitable for people who like to lie on their backs.
At present, the filling materials of pillows are varied. There are chemical fiber, latex, down, buckwheat hulls…Different materials have different rebound times. The better rebound time is 3-5 seconds. Pillows have a service life, ranging from six months to three years. After using it for a long time, problems such as loss of elasticity, aging, and mites will appear.
Synthetic pillows are the most common, but they are not very breathable. Especially after a few months of use, it is easy to be compacted and deformed. The down pillows are relatively soft and comfortable to sleep. But it is difficult to maintain a certain height. It is recommended to use it with a harder pillow.
