What You Should Keep In Mind When Choosing Bedroom Furniture ?
How To Choose A Correct Pillow ?
1. Pillow width:
Under normal circumstances, the width of the pillow is better to be wider than the shoulders. Do not sleep on a pillow that is too small, because when you turn over, the pillow will not be able to support the neck. In addition, a pillow that is too small will also affect the sense of security during sleep.
How To Choose Length, Width And Height :
First of all, it should be required to have enough space. Generally speaking, the length of an adult pillow should be between 50 and 70 cm, the width should not be less than 30 cm, and the height should be about 10-15 cm. Self-examination criteria for replacing pillows: The pillows are lumpy and uneven, and the filling has a damp smell. Such pillows are harmful to health and need to be replaced.
2. The hardness of the pillow:
The hardness of the pillow is also moderate. Because of a hard pillow, the contact area with the head is reduced, the pressure is increased, and the scalp will feel uncomfortable; on the contrary, the pillow is too soft and it is difficult to maintain a certain height, which will cause excessive fatigue of the neck muscles and affect the smooth breathing, which is not conducive to sleep. . Only slightly softer without losing a certain degree of hardness can reduce the pressure between the pillow and the scalp and maintain uneven pressure so that blood circulation can pass through places with less pressure and maintain a certain height.
How To Choose Quality :
Composite high-density polyether polyurethane (tempur) was developed by NASA to relieve the pressure on astronauts, and then gradually used in various medical and civilian products, especially pillows made of this material, which have a sticky Elasticity, it can automatically deform with the change of the position of the head and neck, and keep the position closely combined with the neck at any time, especially to fix the head, preventing the head from slipping and causing “stiff neck”. Self-examination criteria for replacing pillows: After finally adjusting the pillow, it quickly returned to flat. Such a pillow has poor elastic shape and needs to be replaced.
3. The height of the pillow:
The height of the pillow also varies from person to person. Although there is an old saying that “sit back and relax”, it does not mean that the higher the pillow, the better. Because the pillow is too high, no matter what posture you sleep in, it will affect your sleep. It cannot maintain the normal lordosis of the cervical spine, but it will be backward, which will increase the burden on the cervical spine, and may also cause stiff neck. Similarly, a pillow that is too low is not good, because a pillow that is too low will congest the head and easily cause eyelid and face puffiness.
How To Choose Height :
As the saying goes, sit back and relax, but it is not the case. A high pillow makes the cervical spine too forward, and the soft tissues of the neck are overly tense, fatigued, and prone to hair loss. Stiff neck; at the same time, too high a pillow will lead to insufficient blood supply to the brain, which is especially unfavorable for vertebral artery type cervical spondylosis. Conversely, some people like to sleep without a pillow or the pillow is too low.
Generally speaking, our sleeping positions are divided into three types: supine, side and prone. It is best to choose a pillow that can maintain the normal physiological curvature of the neck regardless of whether you sleep on your back or side. It is advisable for an adult to have a pillow height of 15-20 cm when lying on his back, and a height of about 20-15 cm when sleeping on his side. Self-examination criteria for replacing pillows: The pillow has lost its elasticity, and it needs to be patted for a while to restore its elasticity. At this time, the elasticity of the pillow is not enough, which affects the cervical spine.
4. The shape of the pillow:
The problem on the pillow The cervical spine is located at the top of the human spine, wrapped in the neck, and consists of 7 vertebrae. The so-called physiological radian is a smooth, forward-facing arc formed by these 7 vertebrae, and the function of the pillow is to maintain this normal. Physiological curve. How to maintain a normal physiological curvature depends on whether you are really clear about choosing the height, softness and hardness of the pillow.
The height and softness of the pillow are the key. According to the analysis, when a person is lying on his back, the most suitable curvature of the cervical spine is about 3 cm. A pillow that is too high or too low, too soft or too hard will not only affect the quality of sleep, but also affect the health of the body. It is the hidden danger of causing and aggravating cervical spondylosis. A good pillow should be able to support the head and neck at an optimal angle, be moderately soft and hard, quickly return to its original shape after being pressed, and not easily deformed after long-term use.
With traditional pillows, the head rests on the highest point of the pillow, and the cervical spine is suspended, which makes the muscles, ligaments and articular bundles around the neck in a state of tension, and the passage of the vertebral artery is blocked. According to ergonomics, the shape of the pillow with “high front and low back” is most conducive to the health of the cervical spine. This kind of pillow can use the protruding part in front to maintain the physiological curvature of the cervical spine.
Self-examination criteria for changing pillows: In the absence of other physical diseases, I often feel numb and sour in the neck when walking in the morning.
