Is it better to sleep on a hard or soft bed? Unexpectedly, it turned out that they had slept wrong before......

"Sleeping on a hard bed is good for your waist", have you also heard your family talk about it? Some people even add a plank directly to the mattress, so does it really work?

Hard bed VS soft bed

What should I choose?

A mattress that is too soft is indeed not advisable, and I have to say that there is some truth in this sentence.

It is true that using a mattress that is too soft is the largest for the body support area, which can make the bed fully in contact with the torso and increase the sense of security in sleep.

However, in this case, no matter which sleeping position is chosen, the middle of the body will sink and the torso will be curved due to the lack of adequate support.

As a result, the spine cannot maintain its normal physiological curvature, and the muscles around the waist cannot be well rested, which can lead to soreness or strain.

Hardboard beds can also hurt the waist

However, if you often sleep on a hard bed, you may find that you wake up more tired than relaxed.

• Lie on your back with your waist in the air

Due to the "S" shaped physiological curve of the normal human spine, when lying on the hard bed, it will cause the human waist to hang in the air, and it cannot give the waist a certain fit and support.

In this way, even during sleep, the muscles around the lower back still need to work to maintain the curvature of the lumbar spine, which can lead to the inability of the lower back muscles to relax, tension and soreness, and stiffness of the spine, which can lead to strain or straightening of the spine curvature.

• Lying on the side, with a lot of pressure

In addition, a rigid bed may cause more stress on the more protruding parts of the body's bony structure, especially when lying on the side.

Including the shoulder joint, pelvis and other parts, due to long-term compression, the blood circulation is not good, which may cause tenderness, numbness and other discomfort. What is the best mattress? In fact, in most of the relevant studies in recent years, it has been proposed that "medium-firmness mattresses should be the first choice".

• It is recommended to choose a mattress with a certain support capacity

Whether you choose to lie on your back or on your side, the mattress needs to have the ability to support the physiological curvature of the human spine evenly.

Some modern mattresses come in a multi-layer design, including memory foam, latex, and other materials that can provide better support and comfort.

• The 3:1 principle

The 3:1 principle, that is, every 3 cm mattress, you can press down 1 cm by hand.

However, it is also important to note that this is only a reference value, and the specific choice needs to be adjusted according to factors such as the individual's weight, height, and sleeping position.

• Choose the right sleeping position

Choosing the right sleeping position can also help to support the curvature of the spine to a certain extent, so that the muscles around the lower back can be relaxed during sleep, especially for those with low back discomfort or injury.

Supine position

Place a pillow at an appropriate height under the lower limbs, so that the hip joint is slightly flexed to help the waist curvature sink, and the muscles around the waist can be "released" at this time, and the pressure of the retrovertebral disc is reduced.

Lateral decubitus position

Place a small pillow or towel roll under your waist to give your waist some support and relax your muscles.

At the same time, a pillow can be sandwiched between the legs to put the hip joint in a neutral position, which can reduce the pressure on the spine and improve comfort to a certain extent.
