A good sleep cannot be separated from a comfortable pillow. However, some pillows will lose elasticity and slowly deform after being used for a long time, which is not only uncomfortable, but also easy to bring adverse effects to the head and neck. What kind of pillow is good? Recently, American “rodal” news network taught you a trick to help you quickly identify the quality of pillows.
Most of the common pillows in the market are filled with ordinary sponges, memory sponges, cotton, etc. This kind of pillow is easy to deform after being used for a long time, and its elasticity also deteriorates, which can not support the normal physiological bending of the human body. Usually you can try to fold the pillow in half and then release your hand. If the pillow springs back to its original state immediately and there is no obvious crease on the pillow core, it indicates that it is in good use condition; If its rebound speed is slow, or it is easy to leave creases, it means that its elasticity has become poor, and it can not even provide enough support for the head and neck, which will affect sleep and bone health, and cause insomnia, pillow drop, cervical spondylosis and so on.
When buying this kind of pillow, you can also use this method to check. At the same time, you should pay attention to the density of the pillow core. The higher the density, the less likely it is to deform, and the less likely it is for the head to sink in when it is pillowed on it. It can provide sufficient support for the head and make the head feel more comfortable.
