Effects of Pillows on Sleep
Choosing the right pillow is very important in achieving a good night’s rest. A good pillow will support the skull and neck without applying undue pressure, as it conforms to the exact shape of the sleeper, thus spreading the weight evenly and uniformly along the vertebrae.
Pillows are a constant cause of frustration for many. Aside from aggravating the neck, many pillows can affect the shoulder as well. The shoulder should not be placed at 90 degrees to the mattress as this may trigger spasms in the trapezius muscles. The trapezius muscles perform a variety of actions, including acting as a platform for elevating the skull, so it is very important that they relax completely during sleep. If the shoulder is placed slightly forward on the mattress, in front of the sleeper, assuming the mattress can accommodate this position, the risk of applying pressure on the trapezius muscles and forcing the scapula (shoulder blade) towards the spine is reduced. In contrast, when positioned in the 90 degree position, sleepers may wake up with neck and upper arm pain and altered sensation to the little and ring fingers.
If a pillow applies excessive pressure to the neck in the back sleeping position, particularly the C2, C3, vertebrae, then treatment that has been provided will almost always be compromised. Pressure can irritate the nerve sheaths, sensitive muscles, and facet joints in the neck. Equally, if the joints are not resting easy, the inflammatory process may be sustained and any recovery will be much more difficult.
Shoulder compression on a firm surface will often force the scapula (shoulder blade) towards the junction of the upper spine and neck, and affect the C6/C7 vertebrae. The nerve pathway at this site travels down the arm, and causes either upper arm pain or pins and needles in the little and ring fingers or both, especially if there is already a problem in this area.
Shoulder problems are also often caused by referred pain from the neck. Therefore, stabilizing the neck during sleep is of paramount importance! Put some thought into choosing a good pillow - In addition to finally getting a great night’s sleep, you may end up saving yourself from neck and shoulder pain too!
