A good sleep is inseparable from a comfortable pillow. However, some pillows have been used for a long time, and they lose their elasticity and slowly deform, which is not only uncomfortable, but also easily adversely affects the head and neck. What kind of pillow is it? Recently, the US "Rodar" news network teaches you a trick to help you quickly identify the quality of your pillow.
Most common pillows on the market are filled with ordinary sponges, memory foams, cotton, and the like. Such pillows are easily deformed for a long time, and the elasticity is also deteriorated, which cannot support the normal physiological bending of the human body. Usually try to fold the pillow in half and release your hand. If the pillow springs back to its original shape, the pillow core has no obvious creases, indicating that it is in good condition; if it rebounds slowly, or it is easy to leave creases, the elasticity has deteriorated, not even for the head and neck. The Department provides sufficient support to affect sleep and bone health, causing insomnia, stiff neck, and cervical spondylosis.
When purchasing such pillows, you can also use this method to check, and also pay attention to the density of the pillow core. The higher the density, the less likely it is to deform. The more difficult the head is to get stuck when it is placed on the top, it can provide the head. Enough support makes the head feel more comfortable.
