Recently, a friend often complained to Xiaoyou that she was not able to sleep securely at night, and she was prone to dreaming, and she felt irritated during the day and was sluggish. There is also the tossing and turning in bed early and it is difficult to fall asleep......
Modern people are under pressure in work and life, usually stay indoors at work, lack of exercise, play mobile phones before going to bed and stay up late, which really affects sleep quality . But in fact, the reason why you can't sleep well may be because of a point that you overlooked!
Look at a picture first:
In the case of too soft mattress , The human body will sink deeply into the mattress, causing the mattress to squeeze the human body, which is also not conducive to the heat dissipation of the human body; secondly, due to the unbalanced weight distribution of the human body, the waist and abdomen have the largest weight, which will cause the waist and abdomen to sink downwards ; On the one hand, it will also cause deformation of the spine, on the other hand, it will squeeze the internal organs.
Look at the picture again. The human body in the middle of the picture sleeps on a mattress that is too hard. It cannot effectively support the whole body, causing only a few protruding parts to be stressed. This results in one is very uncomfortable and cannot effectively relieve fatigue ; The second is that it will cause the spine to deform; the third is that the stressed parts are too heavy, which is not conducive to blood circulation; so the whole body is uncomfortable with backaches and backaches when waking up the next day.
Therefore, the mattress is too soft or too hard will affect the quality of sleep, lack of energy during the day, and the body will not get very much at night. A good rest will not only affect people's sleep in the long run, but may also cause other health problems.
Two standards for a good mattress:
One is that the spine can be kept straight and stretched regardless of the sleeping position.
The second is that people lying on the top with equal pressure, the whole body can be fully relaxed, and these two points are completely inseparable from the support of the following materials: fabric + comfort layer + support layer = a good sleeping mattress. Among these materials, the comfort layer directly determines the comfort of the mattress.
Common mattress materials on the market:
1. Latex: Latex is the most popular material in recent years. The content of latex in natural latex mattresses is about 85%. Latex is easy to age, and the durability of 100% latex mattresses is very low, so there is no 100% natural latex mattress.
Natural latex mattresses are made of natural latex, and the "gluing" trick is used in the production process. If the mattress turns yellow, there is too much glue. In addition, natural latex has its own unique protein aroma. If there is a peculiar smell or chemical smell, it can basically be judged that it is not a good mattress.
2. Sponge mattress: the mattress is too soft, sleeping on it is not strong enough, so that the lumbar muscles are in tension , Long-term use will damage the health of the waist and easily lead to spine curvature. In addition, its air permeability is not good, it is easy to deform, and it is not easy to dissipate heat. It is good in winter. In summer, the heat is not easy to dissipate, and people are easy to get heat when resting on it. During sleep, wastes and water vapor generated by metabolism will be continuously discharged through the skin, and the mattress is not breathable. These wastes cannot be distributed in time, which is not good for human health.
3. Memory foam: The material of this mattress is a kind of open sticky cell material, which looks like naked eye The touch surface is relatively flat, and the touch surface is very soft and elastic. It takes 3 to 5 seconds to return to its original shape after pressing it down with your hand. It has the characteristics of slow rebound, so it can be adjusted according to the person’s posture to better fit the body curve. It is more comfortable to sleep.

Ordinary people sleep on a memory foam mattress. The mattress has no reaction force on the human body, so it can eliminate the pressure on the body and relax the neck completely. And waist.
Although the memory foam is very good, it has an obvious disadvantage that the mattress becomes soft or hard due to the high or low indoor temperature. However, with the enhancement of technology, there are still many special memory foams on the market that have been improved. Not affected by these reasons later.
