Some people have back pain. When they go to see a doctor, they often get advice: sleep on a hard bed! So they go home to remove their mattresses, put a thin layer of sheets on the bed, and fall asleep, thinking that this is good because the advice is from the doctor. We also often hear that it is healthier to sleep on a hard bed, but can "sleep on a hard bed" really save your waist? It is wrong, actually it hurts you even more!
The physiological structure of the normal spine of the human body presents an S-shaped physiological curve from the side. If you sleep on a bed that is too hard, it cannot match the normal curve of the human spine, and the waist cannot be supported. After a long time, it will easily cause strain and aggravate back pain symptom. A bed that is too hard has a certain impact on the protruding bones and joints of the body. Sleeping on a hard bed requires only a few points on the head, back, buttocks, and heels to withstand the pressure. The spine will be in a state of stiffness and tension, and the back muscles are needed to support it, and the relaxation effect it should have during sleep cannot be achieved.
Some people have said that westerners usually sleep on soft mattresses, is it true that the softer the better? If you lie on a bed that is too soft, your spine will bend and you will feel back pain in the short term. In the long term, this will cause the mid-section of the body to sink, the upper muscles of the body will relax, and the lower muscles will be tightened, which will easily cause psoas muscle and bone strain, and even cause the spine to bend or twist!
The good memory foam mattress perfectly circumvents the above problems with its slow resilience and decompression characteristics. When the mattress is compressed and sags, it will not show a strong rebound force, but will slowly return to its original state after the pressure is removed. In this way, it can well disperse the pressure at the contact point between the human body and the mattress to achieve the most comfortable state. In addition, the memory foam mattress can absorb and decompose the pressure of the human body. People are like floating in the clouds, and the blood is smooth throughout the body, so people will sleep comfortably.
