The mattress is the soul of the entire bed. There is almost no difference between using a mattress directly on the ground and using a bed frame. Of course, there are more criteria for choosing a mattress. In this article, I will clarify some of the "essentials" of choosing a mattress. As long as you choose wisely and avoid the confusion of commercial propaganda, a good night’s sleep is not considered expensive.
A good mattress should be ergonomic and take care of people's behaviors during sleep. In principle, a good mattress should ensure that no matter what lying position the human body adopts, it can maintain the level to the greatest extent, evenly disperse gravity, and avoid gravity gathering to individual parts. Once the horizontal state of the human body changes, the component force of the human body bearing gravity will gather at the lower concave parts, causing these parts to bear extra pressure and cause discomfort.
At the same time, the surface of a good mattress that contacts the human body should have a certain degree of flexibility, so that the contact area between the mattress and the human body is increased, and the pressure of the contact part of the human body and the mattress can be effectively reduced through a more dispersed support. If the mattress is too hard, the contact area between the human body and the mattress will be concentrated on the protruding points, making these points overwhelmed.
The meaning of turning over
Here, we must talk about people's sleep patterns and the effect of "turning over" on sleep. At present, the generally accepted theory believes that sleep related to human body rest and repair can be divided into several stages from shallow to deep. After a normal adult falls asleep, in about 8 hours of sleep, it will experience 4-6 times from light to light. Into the deep and then from the deep cycle. Among them, deep sleep has a stronger function of relaxing and repairing the human body, while light sleep is much inefficient in this respect. If the bed makes people feel uncomfortable, it will cause difficulties in falling asleep and increase the frequency of turning over. On the one hand, people will spend too much time awake in the bed and the limited sleep time will be lost. On the other hand, the proportion of light sleep in the whole sleep process is too high, and the effective deep sleep is insufficient.
Turning over can help avoid hidden health hazards caused by long-term stacking of internal organs, help smooth circulation of body fluids, and prevent snoring. Turning over is a way for the human body to adjust itself. A moderate number of turning over during sleep is inevitable and beneficial. It can be said that even a bed that can provide ideal support cannot replace the positive effect of turning over on the operation of human internal organs. As long as a person is under the earth's gravity environment, turning over during sleep is necessary.
As for the standard of the appropriate number of turns, it depends on the individual's body ratio, weight and other factors. But a simpler measurement standard is: natural turning over is often unconscious and occurs during sleep. Frequent and conscious turning over while awake is usually abnormal. In other words, under normal circumstances, when you wake up, you should not feel that you have turned over on purpose, and you should not leave the impression of tossing and turning. Of course, the frequent adjustment of posture and turning over because of discomfort are likely to be caused by bed problems, but it may also be caused by skeletal muscle diseases and weight problems. For this type of situation, it is not consumer-grade The mattress can be solved.
