What pillows are useful:
First, the pillow filler
Long ago, our ancestors had the tradition of putting medicinal materials in pillows to achieve the effect of sleeping. Pillows filled with different materials have different functions, and the most important thing is whether the fillers are natural and healthy materials. Cotton and buckwheat can sleep comfortably; Lavender, ginkgo, etc. You can keep fit. Different people can choose different herbs or materials and the hardness varies from person to person.
Second, the scientific design of the middle trough.
The design of pillow should be based on the structure of human body. A normal pillow is generally high on all sides, which can facilitate the fixation of the head and support the neck muscles. When choosing a pillow, you must personally try whether the depth of the groove is suitable for the placement of the head, and you can sleep comfortably in any position. And the pillow with weird and twisted groove design, or very shallow or even no pillow, please choose carefully.
Third, the appropriate height.
When buying a pillow, you must pay attention to it. The thicker the pillow, the more comfortable it is. Too high a pillow will affect the support of the spine and neck, resulting in excessive pressure. In fact, it is most comfortable for people to fall asleep with their backs against the wall. Don't believe in rest easy. On the other hand, no pillow is the other extreme, which will also cause sleep fatigue and even induce diseases.
What are the skills in choosing a pillow?
1. When choosing a pillow, the first thing we should look at is the shape of the pillow. Generally, the pillow is located at the top of the human spine, wrapped around the neck and composed of seven vertebrae. Therefore, how to choose a suitable pillow, we must first choose the right one. In traditional pillows, the headrest is usually placed at the highest place of the pillow, and the cervical vertebra is suspended, which makes the joint bundle of musculoskeletal ligament around the shoulder in a state of tension. According to ergonomics, the shape of the pillow is most beneficial to the health of the cervical spine.
2. Whether a pillow is suitable or not is actually related to its hardness. It's not good that the pillow is too hard or too soft. Only by being a little more flexible, without losing a certain hardness, can the pressure between the pillow and the scalp be reduced, the uneven pressure be maintained, and the blood can circulate through the place with less pressure. Therefore, when choosing a pillow, the hardness of the pillow is also very important.
3. The third point in choosing a pillow is the height of the pillow, but the height of the pillow generally varies from person to person, but the higher the pillow, the better. According to research, the pillow height of Asian adults is about 8- 12 meters. But the details should be determined according to everyone's sleeping position. The choice of pillow is best to sleep on your back or on your side, so as to maintain the normal physiological curvature of your neck. Therefore, the pillow height of adults in supine position is 15-20 cm, and the pillow height in lateral sleeping is about 20- 15 cm.
The last thing to pay attention to is the width of the pillow. Generally speaking, the width of the pillow is wider than the shoulder. Don't sleep on a pillow that is too small, so the pillow can't support your neck when you turn over. In addition, too small a pillow will affect your sense of security when you sleep. Therefore, it is suggested that the length of adult pillows should be 50-70 cm, the width should be not less than 30 cm and the height should be about 10- 15 cm.
