(1) should have the right height.
Lying on your back has the height of lying on your back, lying on your side has the height of lying on your side, with a high neck and a low head.
(2) Have a reasonable curvature.
The pillow fits the natural physiological curve of the head and neck, so that the head and neck are fully and naturally supported.
③ Comfortable soft and hard (elasticity).
Too little elasticity feels too hard; If the elasticity is too large, the reaction force will increase and the sense of oppression will increase.
Second, how to choose a pillow that suits you?
Mainly according to their sleeping position, height and pillow type.
1, favorite sleeping position (primary factor)
Lying on your side: Keep your spine straight with a high pillow, so that you can fully relax and sleep better.
Dinner: The pillow of medium height provides the most adequate support for the head and neck, making the whole body relax.
Prone: Choose a low pillow to minimize the degree of muscle sergeant and the pressure on the neck.
2, the height of the pillow
Traditional adult pillows are 60-70 cm long and 35-43 cm wide. The results showed that the occipital bone in lateral position was 5-7 cm; Supine neck pillow:10-12 cm; Side face pillow: 12- 14cm.
3. How to judge whether the pillow is too high or too low?
Too high or too low a pillow can cause sleep discomfort, and the height of the fist is usually used as the height of the pillow. Generally speaking, patients with hypertension, heart disease and asthma sometimes need high pillows; People with low blood pressure and anemia sometimes need low pillows.
① The general pillow height is 10-375px. It also depends on the physiological characteristics of people, especially the physiological curvature of the neck. People with broad shoulders and fat bodies have slightly higher pillows; And thin people can be lower.
Sleep habits also affect the height of pillows. For people who are used to sleeping on their backs, the height of the pillow should be equal to the height of the fist after speaking. For people who are used to sleeping on their side, the height of the pillow should be consistent with the shoulder width after pressing. Of course, a pillow that can keep the normal physiological curvature of the neck regardless of sleeping on your back is the most ideal.
4. Judge the hardness of the pillow according to the height and weight.
An excellent pillow will make the scalp uncomfortable. A pillow that is too soft can't support the weight of the head, so choose one with moderate hardness. Some people prefer spring pillows and air pillows. These pillows are too elastic. When sleeping, the cervical vertebra should constantly resist the external elasticity, which is not good for the body.
