If the mattress is not close to the body, the waist will be suspended, and the waist muscles will be tense for a long time, and they will not be supported and relaxed. Over time, it will cause lumbar muscle strain and seriously affect health.
How to judge whether a mattress is close to the skin? When buying a mattress, try to lie on the mattress and put your hand in from the waist down. If you can enter easily, it proves that this mattress is not close to your body and is not suitable for you to buy. It is difficult to choose to enter, and it is appropriate to have a squeezing feeling in your hand. Second, ventilation.
People excrete about 250 ml of sweat every night during sleep, some of which will evaporate and most of which will be absorbed by bedding. Sweat contains salt. If the mattress is airtight, it is easy to breed bacteria and mites, causing skin allergies, acne and other skin diseases, affecting health. There is a saying that if you don't stay in bask in the quilt for 3 days, 6 million mites will sleep with you.
The air permeability of the mattress depends on the fabric of the mattress. Knitted fabrics are widely used in the market. Knitted fabrics have good breathability, such as Tencel fabric, 3D fabric and 5D fabric, which are all very breathable materials. The fabrics with poor air permeability are brocade, chemical fiber and flower ballad cloth, and the air permeability of these fabrics is very general, so when choosing a mattress, you must ask what fabric it is. Third, environmental protection.
Not only the choice of mattress should be environmentally friendly, but also the choice of home improvement and furniture must be environmentally friendly, otherwise it will affect people's health and induce physical diseases.
The environmental protection materials of the mattress are: latex, memory cotton, aerobic cotton, 3E coconut dream green brown, 3D materials, etc. Some mattresses will also add bamboo charcoal cushions. Bamboo charcoal has the functions of pest control, deodorization, dehumidification, deodorization, formaldehyde decomposition, air purification, negative ion generation and so on. Therefore, a good mattress not only makes people sleep comfortably, but also makes people who sleep have healthy bodies. Medicine tonic is better than food tonic, and food tonic is better than sleep tonic. Only by having a healthy body can we get more wealth.
