There are many disadvantages in using sponge as a mattress: firstly, it is too soft, and it will hurt your back if you sleep for a long time. Growing teenagers can't use cushions. Secondly, because sponge is poisonous, it is mainly bad for the waist. The human body has a natural forward bend in the waist and neck, and the sponge mattress is relatively soft, so people can't form the strength to lift the waist when lying down, which leads to long-term tension of the lumbar muscles, which will cause lumbar muscle strain and lumbar disc herniation for a long time. The third sponge has too many gaps, poor air permeability and easy absorption of too much water, which can easily lead to the growth of bacteria, mites and other microorganisms in the sponge, affect your immunity and do great harm to your body.
First, sponge mattresses are soft and not suitable for long-term sleep.
The mattress should keep the spine level when sleeping on the side, and support the whole body weight on the back. Among them, the waist with relatively weak muscles needs support most. Sponge mattresses are too soft to fully support the human body and are not suitable for long-term sleep.
Second, sponge mattresses are poisonous.
Sponge mattresses mainly include latex and sponge. If the selected sponge contains diethyl toluene dicyanate, there will be formaldehyde problem if more glue is added in the production process. At present, most mattresses are equipped with sponges. Some inferior sponges contain more harmful substances, which will naturally do more harm to the body. Some sponges are better, and the formaldehyde content is relatively less. They can pass the inspection of professional equipment, and the impact on the body will be less, but they will all have a certain impact on the body.
Third, the sponge mattress has poor air permeability and poor support.
Sponge mattress is not breathable, and waste and water vapor generated by metabolism will be continuously discharged through the skin during sleep. The mattress is airtight, so these wastes cannot be distributed in time. Moreover, the sponge mattress is not particularly sensitive to temperature, nor can it fully support the shape curve. Moreover, due to the poor supporting force of the sponge mattress, it is very inconvenient to turn the mattress over every once in a while to avoid the collapse of the sleeping place of the human body, frequent movement of the mattress, waste of time, and easy damage to the internal structure of the sponge mattress.
To sum up, Bian Xiao thinks that the mattress is not suitable for choosing a sponge mattress.
