Introduction: Many people are using close to a kind of pillow is flat rectangular pillow, this pillow has a long history though, seems practical and generous, but it does not meet the body's physiological requirements, long-term use may damage human cervical physiological curvature leading to neck muscles, ligament stress state in a long time to get enough rest and neck strain.
There is usually such a feeling: wake up, suddenly found himself unable to move too stiff neck, general back pain, clearly not slept the night you feel, how the worse the sleep the more tired? If you had a similar experience that time you will need to carefully check whether it is checking your pillow physiological curvature of the neck.
Pillow problem: cervical spine at the top of the body, including in the neck which, by the seven vertebrae. The so-called physiological curvature is formed by these seven vertebrae of a sleek, towards the front of the arc, the role of the pillow is to maintain the normal physiological curve. How to maintain the normal physiological curvature, we must look at your level of software and hardware in the choice of the size of the pillow is not really clear.
Pillow height: This is also vary, the old saying where though "peace of mind" argument, but it was not the pillow higher the better. Because the pillow is too high, no matter what position to sleep can affect sleep, can not maintain the normal lordosis of cervical curvature, but will be back, and this will increase the burden of cervical vertebrae, but the phenomenon may have stiff neck. Similarly, the pillow is too low is not good, because the pillow is too low will head congestion, likely to cause swelling of the eyelids and face, and jaw will therefore lift up, easy to mouth breathing, snoring of the situation there. Generally speaking, our sleep posture into supine, lateral, and prone of three. Pillow is best choice regardless of their backs, positional, can maintain normal physiological curvature of the neck. When adults to sit 15 to 20 cm high pillow, pillow when positional height of about 20 to 15 cm in height is appropriate.
The hardness of the pillow: This is also advisable to moderate. Because the perfect pillow, and head to reduce the contact area, pressure increases, the scalp will feel uncomfortable; the other hand, the pillow is too soft and difficult to maintain a certain height, would lead to neck muscle fatigue and the impact of smooth breathing is not conducive to sleep . Only slightly more flexible, without losing a certain hardness to not only reduce the pressure between the pillow and scalp, while maintaining uniform pressure, so that blood circulation can be passed from a less stressful place, and maintain a certain level.
The width of the pillow: Under normal circumstances, it is best to be more than shoulder width and not to sleep too small pillow, because when you a stand up, can not support neck pillow, another pillow is too small sense of security will also affect sleep.
