Mattress: The protector of the human spine

The spine is the main supporting point of the human skeleton and the center of gravity of the skeleton. Therefore, we must provide good protection for our spine, especially when we sleep, we should allow the spine to be completely relaxed. Viewed from the left and right sides of the human body, the spine is not straight, but presents a three-section S-like arc. Therefore, when choosing a mattress, we should see whether it can maintain the original healthy curvature of our spine.
Too soft and too hard are not good <br> If the bed is too hard, hard bed does not meet the needs of the body curve, people lying on the top will make the waist vacant, can not support the lumbar spine, must rely on the back muscles support The spine, so that the spine is in a state of tight tension, not only does not achieve the purpose of allowing the spine to rest and muscle relaxation, but will cause serious damage to the body. In conclusion, a suitable mattress can fill the virtual position that appears between the back of the waist and the bed.
Mattresses are not as soft as possible. Mattress is too soft, the body's compression site is easily deformed, so that the spine bends or twists, thus changing the body's normal spinal curvature, so that the relevant muscles, ligaments are tightened, long time can not be fully relaxed and rest, there is backache leg pain feel. Over time, it will accelerate muscle strain and the aging of spine bones, and even cause spinal deformities.
Purchase a suitable mattress
When buying a mattress, it's best to lay yourself on the bed and it's important to try sleeping on it.
1, first sitting on the edge of the mattress, stand up, if found that the mattress seated in the subsidence, that the mattress is too soft; lying on the bed, try to insert the palm into the gap between the waist and the mattress, if the hand can be easily Interspersed in the gap, that is, the bed is too hard; if the palm tightly close to the gap, it means moderate hardness; if you buy a double mattress, it is best to test together, the heavier side can turn over on the mat to see if the mattress is shaking Will affect the other party.
2, touch and pat on the bed, such as in the above can touch the spring, then the pad material is too thin, it will be sleeping and feel uncomfortable. If you use your hand to pat your bed, it feels a little “tossed” or “empty.” This means that there is a gap between the liner and the pad, which does not effectively support the body and is easily deformed.
3. Look at whether the mattress can stand upright and erect the mattress upright. If it is bent or cannot stand up, it means that the mattress is rough.
4. Observe if there is a jumper at the seam of the surface.
One-third of your life is spent in bed, so the mattress must be suitable.
