Many people will have lumbago, I heard that sleeping on a hard bed is good, the result is that every day to sleep on the board, but lumbago is not much better, especially when it is cold, but more serious, what is going on? The normal human lumbar spine has a curvature, as if a brace – “(“, the brace convex forward. If you sleep on a soft bed, just lying down feels very soft and comfortable, but this is only a tactile sensation of the skin, and so on after falling asleep, the muscles are very relaxed, so that the bed will travel under the weight of the body into a middle low two high form, at which point the brace arc concave backward – “) “. Like still bending labor, it is easy to cause soft tissue strain on the muscles and ligaments of the low back. So people who sleep on soft beds such as Simmons will feel tired in the morning, not relieved, and over time, this will lead to local soft tissue imbalance, affecting the physiological curvature of the lumbar spine, so that the lumbar intervertebral discs are unevenly stressed.

But the extent of hardness is rarely explained too much. Obviously, if it is just a hard board, which does not conform to the physiological curvature of the sphincter convexity forward, and nothing is padded, the cold will make the muscles tense and even contracture, which will also aggravate the back pain. The ideal and reasonable approach is to lay one or two bedding or palm pads on the board. This sleep on it, it will form a slight deformation with the body’s convexity, just in line with the body’s physiological curvature, to a large extent to maintain the balance of the lumbar spine, skin touch or.
