Sleep is the foundation of health. One-third of life is spent in sleep. The four major signs of whether people have a "healthy sleep" include sufficient sleep, enough time, good quality and high efficiency.

How to have healthy sleep?

In addition to work, life, physical, psychological and other reasons, having a hygienic, healthy, beautiful and durable bedding is the key to high quality sleep.

The quality of sleep is closely related to the mattress. When choosing a mattress, consumers can choose from the breathability, decompression, support, compliance, sleep temperature, and sleep humidity of the mattress.

A good mattress not only enables a person to have a comfortable sleep, but also is great for the body. Generally speaking, long-term incorrect sleeping positions, especially use the poor mattresses, can cause spine displacement. A mattress that is too hard not only compresses the nerves in the back of the body, but also affects blood circulation.

There are two standards for a comfortable mattress:

Regardless of the sleeping position, the spine can remain straight and stretched.

The pressure is equal, and the whole body can be fully relaxed when lying on it.

It will involve the softness of the mattress, which depends on the mattress's fabric, spring, filler, etc.You can view the passage " How to choose a mattress? " for details.

When a person lies on a mattress that is too hard, the body has only four supporting points: head, back, buttocks and heels, and other parts cannot fit the mattress completely. The spine is actually in a state of tension, which not only fails to achieve the best resting effect. And sleeping on such a mattress for a long time will damage your health.

A mattress that is too soft makes the whole body sink in it when lying down, and the spine is bent for a long time, causing pressure on the internal organs. For a long time, it is also unhealthy and uncomfortable.

Therefore, a mattress with moderate hardness should be used.
