What kind of bed do I sleep in with a herniated disc? Is it recommended to sleep on a hard bed?

Here I make it clear that I am strongly opposed to sleeping on a hard bed for patients with herniated lumbar discs! What bed for lumbar disc herniation, a search on the Internet, out of a bunch of answers, many answers are said to sleep on a hard bed to relieve lumbar pain, but also to treat lumbar disc herniation, sleep on a hard bed is good, but is it really so? Before answering this question, we first understand the normal anatomical structure of the lumbar spine, the lumbar spine is a physiological convexity, from the side like a “C” shape, all change this physiological convexity of the posture of the lumbar spine there are different degrees of damage. So we should try to maintain the physiological lumbar convexity of the lumbar spine in our sleeping posture. So how to maintain the normal curvature of the lumbar spine while sleeping? The answer is to ensure that the mattress is soft and hard to fit the body curve, the body curve and the mattress match, no gap is best. We try to ensure that the lumbar spine in a neutral position when lying on the side, many people’s waist on both sides is curved, especially girls with good figure, so we are in the side position it, to try to ensure that the lateral curvature of the lumbar spine and mattress fit, no gap. And in the supine position, try to maintain the physiological convexity of the lumbar spine, so our lumbosacral to fit with the mattress, there is no gap, keep the mattress on the waist has an upward support, if necessary, you can pad a small pillow in the waist, the waist arch, so that the most comfortable to sleep. So sleep must choose a soft and hard mattress, neither too hard, nor too soft, the online rumors of sleeping on a hard bed is not based on any theory, if there are benefits of sleeping on a hard bed, then we simply sleep on the floor is not better, how hard the floor, is not it? If you want to know if your bed fits, okay? In the side-lying position when you put your hand next to your waist, see if there is a gap. In the supine position it, put your hand behind your waist, see if there is no gap, if there is no gap, which means that the mattress fits well with your waist, is a better bed, if there is a gap, then change the mattress as soon as possible.
