Please throw the ergonomic bed out of the door decisively.
An inappropriate mattress has become a "spine killer"
People's spine is inverted "S" shape, and it is straight when sitting or standing during the day. Relax by sleeping, so as not to be in a state of tension all the time. If the mattress is too hard, the protruding part of the spine cannot fit the mattress during sleep and is in a suspended state. Over time, it will compress the nerves, cause lumbar muscle strain, and even long bone spurs. If the mattress is too soft, there is no suitable support point and support force.
It's not good for sleep either. In particular, what science sister needs to say is that the skeletal development of teenagers is closely related to mattresses. Too hard or too soft mattress will cause spinal dysplasia. What is a good bed?
The mattress is too hard and soft.
Studies have shown that normal people will turn over 30 to 60 times in their daily sleep. The elasticity of the mattress can overcome the weight difference of different parts of the body. A good spring can stably support the strength of various parts of the body, such as shoulders, hips and waist, and avoid uneven stress caused by excessive sinking of the mattress.
The research of experts all over the world shows that both hard mattress and soft mattress are not conducive to healthy sleep, and the ideal bed should be moderate in hardness. A cotton pad with a thickness of about 10 cm on a wooden bed has the best hardness. Such a thick cotton pad can meet the needs of human body surface curve and maintain the integrity and normal physiological curvature of the spine.
This is good for sleep and health. The height and width of the bed are particular.
Besides the hardness of the bed, we should also pay attention to its height. The height of the bed is generally about 40~50 cm, that is, it is better to be slightly higher than the knee of the sleeper. This way, you can go to bed without any effort, and you can stretch your legs and wear shoes when you get out of bed.
The bed should be wider. Generally speaking, its length is 20~30 cm longer than that of the sleeper, and its width is 30~40 cm wider than that of the sleeper, so that it can stretch when sleeping, which is beneficial to blood circulation and fatigue elimination.
The bed material is based on the principle of comfort.
The bedside and bedstead are made of many materials. The choice depends on personal preference, but there are still some comfort principles. For example, if you like reading in bed, you'd better choose a soft and comfortable cloth bedside.
If you like the romantic and classical elegance of the countryside, the quaint wooden bedside and beautifully carved wrought iron bedside are the best choices, but the guardrail, the end of the bed or the bedstead are too wide.
Especially the American big bed is not suitable for small and medium-sized bedrooms, because it will occupy most of the bedroom area, which will bring inconvenience to layout and use. Choosing pillows by "muscle energy method"
American chiropractic has a muscle strength evaluation method called "muscle strength test", which is very effective in choosing pillows.
The steps of this test method are as follows: lying on different types of pillows, and then raising your arm to test your arm strength. When your arm strength is the greatest, it means that this memory pillow conforms to your cervical curve, because your cervical nerve is the most unobstructed and your arm is the most powerful at this time, so you can buy this pillow with confidence. The key points of pillow selection are: whether sleeping on your back or on your side, you can keep the normal physiological curvature of your neck.
1. The thickness of both sides of the pillow is appropriate, and the cervical spine can be well supported when sleeping on the side.
2. Generally, the height of cervical vertebra is 6 cm, and the height of adult pillow is suggested to be about 6 cm; The height of children's pillows increases with age, and the height of pillows for children aged eight or nine is 3 cm.
3. The width of the pillow is proportional to the shoulder width.
4. Good elasticity. Free from extrusion deformation, can naturally bear the weight of the head and neck.
5. Wavy radian design, the head can be fixed on the pillow.
6. Various materials have different characteristics, so ventilation should be considered.
Down pillow is comfortable, but not suitable for allergic patients; Synthetic fibers have no allergic problems, but they don't sleep well. In addition to using the "muscle energy method" to choose a mattress, you can also try to see if you can lie out of sleep.
First, if you can lie flat on it quietly for more than ten minutes and feel sleepy, that is the mattress that really suits you (of course, the premise is that there is a pillow that suits you), because a good mattress and pillow should not only conform to the curve of the human spine, but also reduce the pressure on the human body.
Method 2, you can also use the "muscle energy test method" to test: lying on different types of mattresses, bending and stretching your legs upwards to test your leg strength. The mattress with the strongest leg strength is one that conforms to the curve of your spine, because at this time, your spinal nerves are the most unobstructed and your legs are the most powerful. This mattress is suitable for you.
There are two key points in the choice of mattress: waist support and shoulder and hip comfort.
Lumbar support
When choosing a mattress, you might as well lie down for a while. If you obviously feel a sense of emptiness in your waist, then this mattress is not what you need even if it is hundreds of thousands. If you lie on your back and feel that you need to curl your legs to feel comfortable, it's because you already feel obvious pressure on your waist and need your hip joint to share the weight.
Comfortable shoulders and hips
Lie down on your side and feel the pressure on your shoulders and hips. If you feel stressed after a few minutes, it proves that the mattress is too hard for you. Although there is enough support, it is quite lacking in comfort, which is also not suitable for you, and may also lead to poor blood circulation during sleep.
