Good sleep is very important for us, and pillows can be said to directly affect our sleep quality. Some people say that pillows need to be higher and better, while others think that lower and better. Will the height of pillows affect sleep? Which is right? Xiaobian will tell you.
How high is the pillow
There is an idiom called "have a good rest". The fact that the pillow is too high is not a worry. When sleeping, the high pillow will make the head lean forward and the neck bend forward, so that part of the upper respiratory tract is twisted, which is easy to cause suffocation; especially for the middle-aged and old people with poor heart function, the high pillow will increase the difficulty of the heart supplying blood to the head, thus increasing the burden on the heart. High pillow may also cause 'falling pillow', which may lead to cervical spondylosis for a long time. Of course, the pillow should not be too low, or because of the flow of human brain blood partial, wake up in the morning puffy eyelids, dizzy brain up. The appropriate height of the pillow is about 15cm, which is generally equal to the shoulder width of one side.
High pillow or low pillow
When it comes to this, it's easy to think of "rest assured". But in fact, the higher the pillow, the better. Too high pillow will cause the cervical vertebra to lean forward, destroy the normal physiological anterior curvature angle of the cervical vertebra, and then compress the cervical nerve and vertebral artery, causing the symptoms of neck pain, head hypoxia, headache, dizziness, tinnitus, insomnia and other brain neurasthenia, and prone to hyperosteogeny.
In the same way, low pillow has a great harm to the cervical spine. Although it is not as serious as not sleeping pillow, it will easily cause or aggravate cervical spondylosis after a long time. In addition, low pillow will also affect the balance of blood supply to the brain, resulting in dizziness, affecting sleep.
When should I change the pillow
In general, the pillow should be replaced once every 2 to 3 years. If the pillow is too long, a large number of mites and molds will grow, which is easy to cause respiratory or allergic diseases. If you always feel numbness and pain in the neck after getting up, the pillow loses a certain amount of elasticity and has lumps and bumps, you need to change the pillow in time.
