1️⃣ A comfortable mattress can not only bring good sleep, but also benefit the lower back and spine. Everyone's requirements for mattresses are different, and the ➡️ general principle is: to make the body as relaxed as possible, naturally, too soft, too hard mattress is not suitable.
.
The choice follows the hardness 3:1 principle
🤔 Normal spine has 3 physiological bends, the body "nest" in the too soft bed, due to the lack of sufficient support, may lead to the middle of the spine sinking, ligaments around the spine, intervertebral overload, long time, easy back pain.
⚠️ People with lumbar disc herniation, scoliosis, the elderly, and children and adolescents with developing spines are not suitable for sleeping on soft mattresses.
In terms of hardness, the mattress should have the following 👇 standards: lying flat, the hand is flat to the neck, waist, hips to the thighs three places, to see if there is a gap; turn to the side, use the same method, see if there is a gap between the body depression and the mattress; if the gap is too large, the bed is too hard; the curve fits to show that the soft and hard is appropriate. You can also choose a mattress hardness: 3 cm thick mattress according to the "3:1 principle", and the hand presses down to sink down to 1 cm; the 10 cm thick mattress, which is about 3 cm down is more appropriate.
We often hear 👉: the doctor let you sleep on a hard mattress is not a hard bed board, the so-called hard mattress is relative to some particularly soft spring mattress, the right choice is a mattress that has a good fit when you have enough support for your waist.
Hardboard beds not only fail to "save" the waist, but may make the waist more and more tired the more you sleep 💤. Normal people's lumbar spine has physiological precocity, the larger is more than 70 degrees, the smallest is not less than 30 degrees, lying flat on the hard board bed, the chest and hips constitute the fulcrum, and the waist is in a suspended state.
!️ Under the action of gravity, the lumbar muscles and ligaments are very easy to fatigue, and in the long run, they can even cause damage to the lumbar spine. A hard bed can also compress the tissue under the back, making people involuntarily turn over to change the area of oppression. In this way, "turning over" will further affect the quality of sleep.
