One third of the time in one's life is spent in sleep, so high quality sleep is also an important premise of health, so the harder the mattress, the better, or the softer the better? Let's get to know.
Hard mattress
A good mattress can affect blood circulation.
The physiological structure of the normal spine of the human body shows an S-shaped physiological curve from the side. If you sleep in a board bed that is too hard, you can't match the normal curve of the spine of the human body, you can't get support for the waist, and if you have a long time, it is easy to cause strain, increase backache and other symptoms.
A good bed also has some influence on the protuberant bones and joints of the body. Sleeping in a very hard bed, only the head, back, buttock and heel bear the pressure. The spine will be stiff and tense. It needs the muscles of the back and waist to support it. When sleeping, it can't achieve the effect it should have.
In fact, generally speaking, the "hard bed" refers to a bed with a mattress thickness less than 10 cm, compared with a very soft bed such as Simmons.
People who often have low back pain go to see a doctor and are often advised to sleep in a hard bed. Is it really so good to sleep in a hard bed? A hard bed is not equal to a hard board. The doctor's advice for sleeping on a hard bed is to make you use a thinner cushion on the basis of a hard bed. In other words, don't sleep too soft, but don't sleep too hard.
Soft mattress
Some people say that Westerners sleep on soft mattresses, and the softer the mattresses, the better.
Scientific research has proved that too soft mattress, when the human body lies on it, will make the spine curved, and will feel backache in the short term. In the long term, it will cause the middle part of the body to sink, the upper part of the body to relax, and the lower part to be tensed, which is easy to cause lumbar muscle and bone strain.
It should be noted that, especially in the growth and development period of children, if they sleep in soft bed for a long time, it will seriously affect the development of their spine, resulting in hunchback, spine bending and deformation.
From the above can be summed up, in the selection of mattresses, the first thing is to keep the spine straight and stretch, so that no matter what sleeping position, it can give a good sleep state. Secondly, the pressure should be equal. As long as people can relax in bed, they can choose the right mattress according to their height, weight and sleeping posture. Most people who weigh more than 80kg should choose some harder mattresses.
In addition, what kind of people should pay special attention to mattress selection?
Aged:
They often have waist and leg pain, osteoporosis, lumbar muscle strain and other problems, so we need to pay special attention to mattress selection. Too hard mattresses make them uncomfortable to fall asleep, while too soft mattresses are not good for these problems, and it is more difficult for them to get up, with the risk of falling. Therefore, we should pay special attention to the choice of soft and hard mattress.
Teenagers:
They are in the stage of growth and development. If they sleep on soft mattresses for a long time, it will affect the development of spine, leading to hunchback, spine deformation and bending. Therefore, it is better to let them sleep on a harder mattress, and often pay attention to the height of children's shoulders, faces and eyes, whether there is scoliosis.
Pregnant woman:
When they lie on their side, if they sleep on a soft mattress, it will increase the pressure of the uterus on the abdominal aorta and the inferior vena cava, reduce the blood supply of the uterus and affect the fetus. Therefore, should not sleep over the soft mattress, to choose a moderate soft and hard mattress.
