in many people’s ideas, sleeping in a hard bed is good for the body’s bones and won’t be sore when getting up. However, not everyone can sleep in hard beds, and hard beds are not what people understand & ldquo; Hardwood Bed & rdquo;. Let’s follow and have a look.

If the bed is too soft, the pressure of human body weight will make the middle of the bed low and the surrounding high, which will affect the normal physiological flexion of the lumbar spine, resulting in the contraction, tension and spasm of lumbar muscles and ligaments. However, a too hard bed will also oppress some parts of the human body, resulting in an increase in the number of turns during sleep and insufficient rest. In addition, people’s spine is S-shaped, the bed is too hard to maintain the normal curve of the spine, the waist can’t get support, and they will have low back pain after getting up.

generally, patients with lumbar protrusion and low back pain and some patients in the rehabilitation period after fracture surgery should sleep more on a hard board bed. Normal people and infants should not sleep in a too hard bed, especially from birth to the age of 3. If the bed is too hard, it is unfavorable to the child’s bone development.

if the home is a hard board bed, you can put about 10cm thick mattress on it, or put a brown mattress on the board bed. If you still feel hard, you can add 5 ~ 8cm thick mattress. There is a simple way to judge whether the hardness of the bed is appropriate: lie flat on the bed and press your hands under your waist. If your hands feel compressed and not easy to pull out, it means that the hardness is appropriate.

What are the criteria for a good bed?

first, whether a bed is good depends on its softness and hardness. When buying a bed, it is recommended to lie down and try

a healthy bed. After lying down, people will not feel sunken. When lying flat, they feel that there is a palm that can be extended between their waist and the bed, rather than no gap at all. If there is no gap at all, it is likely that the bed is too soft. If the gap is too large, it means that this bed is a little too hard and is not recommended.

second, air permeability is also a standard to judge whether the bed is good or not

our body needs to excrete a lot of sweat every day, which can reach as much as 750ml. Among them, nearly one-third of the sweat will be absorbed by our mattress. Therefore, it is very necessary to choose a mattress with good air permeability. Mattresses with poor air permeability are prone to mildew, spring rust and other problems, breeding more bacteria and mites, which is very unfavorable to our health.

third, the environmental protection standard of the bed is also the standard to judge whether it is the No. bed

according to the national standard requirements, the formaldehyde content in the mattress shall not exceed 0.050mg/m2. H. If the formaldehyde content of the bed you buy exceeds the standard, sleeping in this bed for a long time will bring great harm to our body, so when selecting the bed, we must see whether the environmental protection of this bed meets the standard. In fact, a hard or soft bed is unfavorable to the health of the waist. Because the whole person has fallen into a soft bed. In this case, our waist is not supported. If so for a long time, it is easy to feel low back pain, which is very unfavorable to the health of the waist. A hard bed will lead to the waist hanging in the bed, which can not fully relax and rest the waist, lead to the stiffness of the muscles of the waist, and cause waist diseases such as lumbar muscle strain.

Eight prescriptions for mattress maintenance

1. Regularly adjust the direction: after the newly purchased mattress is put into use, the front and back direction and up and down turning action shall be done every three months in the first year, so as to make each part of the mattress stressed evenly and increase the service life of the mattress;

2. Maintain air circulation: in order to ensure that the interior materials of the mattress are not affected by moisture and increase the comfort of the mattress, it is necessary to maintain air circulation in the room where the mattress is used;

3. Avoid single point jump or fixed-point heavy pressure on the mattress, and avoid standing on the mattress or single point jump or fixed-point heavy pressure, which will cause uneven stress on the mattress, and avoid sitting on the edge for a long time and shorten the service life of the mattress;

4. Do not use water to clean the mattress: in case of liquid pouring and penetrating into the inner layer of the mattress, do not use water to clean it. Immediately squeeze it with a cloth with strong moisture absorption until it is absorbed, and then use a hair dryer to cool and warm air (hot air is strictly prohibited) or an electric fan to dry it. In addition, do not use dry cleaning liquid to clean the bed surface, which may damage the cloth surface;

5. Do not smoke in bed or place the mattress near the flame;

6. Use the cleaning pad: in order to ensure the hygiene of the mattress, cover the cleaning pad before covering the sheet;

7. Matching of upper and lower mattresses: do not put boards between the upper and lower mattresses or place the upper mattress on the damaged old mattress. You can buy matching mattresses to prolong the service life and sleep comfort of the new mattress. If the surface of the mattress is polluted, you can scrub it with alcohol in time;

8. Handle with care: when handling, place the mattress on the straight elevation and do not bend or fold it. This will damage the shaped frame of the mattress and cause the mattress to twist and deform.
