Bed, physical safety. In ancient times, it was also called "couch", which was often short and hard for people to sit and lie down; Now it is only used for sleeping. It is both soft and hard, soft and comfortable, and has various functions. With such "advanced sleeping equipment", it stands to reason that villagers should enjoy sleeping every night, so why complain? However, it is precisely because of the softness and hardness of the bedding that the villagers have their own rhetoric! Is it better to sleep in a hard bed or a soft bed?
How to choose a bed
How about sleeping on a hard bed? Relieve fatigue
The ancients always said: "Sleeping in a hard bed can relieve fatigue, because the bed is too soft and will touch the skin. The bed only touches the skin and will not massage the bones and muscles. On the contrary, it will make people more tired, but the hard bed will not. Moreover, the hard bed can also prevent the spine from bending and help to correct the "irregularity" of the spine caused by the daytime, so there are many "curative effects" besides health care. For example, sleeping on the hard bed for teenagers can prevent hunchback, low back pain and flexion and extension difficulties, and can relieve pain.
In addition, sleeping on the hard bed often can also enhance the skin function, improve the functions of organs such as liver, kidney, stomach and intestine by stimulating the skin, and prevent and treat visceral diseases such as constipation, intestinal cancer and cerebral hemorrhage, which has many benefits. No wonder the ancient people slept in hard beds as well as hard pillows. Now hospitals are also hard beds. Therefore, it is reasonable to announce the "health preservation" of the hard bed.
However, Thomas Laaser, a German professor, does not agree with this. He thinks that the hard bed can not meet the needs of human body curves, but will cause serious burden and various injuries to muscles and spine.
How about sleeping in a soft bed? comfortable
Soft bed, soft and comfortable, more full and intimate contact with the skin, and stronger sense of security during sleep. For grapefruit, a sister paper with sensitive skin and body, the softness of the soft bed and the design that perfectly fits the physiological curve of the human body can better meet the needs of grapefruit.
But the soft bed is too soft, because no matter which posture is taken, the middle part of the body will sink and the trunk will form an arc, which will overload the ligaments around the spine and increase the physiological curvature of the lumbar spine, which will cause low back pain for a long time; Especially for patients with osteoarthropathy such as lumbar disc herniation and proliferative spondylitis, sleeping in a soft bed for a long time will aggravate the symptoms. In addition, sleeping in a soft bed often makes the muscles trapped in the mattress unable to relax, and the internal organs of the chest and abdomen are easily oppressed and can not get enough rest.
Too hard or too soft is not good for health.
The choice of bed and sleeping equipment is best from the perspective of health care, considering whether it conforms to the physiological characteristics of the human body and whether it is conducive to sleep. So, what kind of bed is best for sleeping?
In fact, the ideal bed is neither too soft nor too hard, and the hardness should be moderate. A cotton pad with a thickness of about 10 cm on the wooden bed has the best softness and hardness. Such a thick cotton pad can meet the needs of human body surface curve, maintain the integrity and normal physiological curvature of the spine, and is beneficial to sleep and health.
In addition, in addition to 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. In this way; You don't need to get up hard. 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 result of entanglement:
To sum up, the best healthy bed should meet the following requirements: First, it must conform to the shape of the body. Second, the pressure on the contact surface between the bed and the body must be dispersed to achieve an average. Third, the supporting force of the contact surface between the bed and the body must be balanced, and the gap should not be too big.
What kind of bed is best for your health?
We know that there are all kinds of beds. Some people like softer beds, while others like harder beds. Which is better, a soft bed or a hard bed? Let's make an analysis and comparison of various beds first.
Simmons bed is too soft.
This kind of bed is breathable, but most of it is thick and soft. From the perspective of prevention and treatment of cervical spondylosis, the bed should not be too soft. Too soft a bed will cause a state of low in the middle and high in the outside because of the weight compression of the human body. This will increase the tension of the muscles lying on the back, and will inevitably lead to a relative increase in the posture of the head and neck. Just like a high pillow, it will lead to local muscle ligament imbalance and directly affect the physiological curve of the cervical spine itself. After a long time, it will accelerate the degeneration of cervical spine and directly lead to the occurrence of cervical spondylosis.
The wooden bed is too hard.
Is this kind of hard bed good? Wooden bed can keep the balance of spine, which is beneficial to the prevention and treatment of cervical spondylosis. It should be a good bed. But everyone who sleeps on a hard bed knows that the bed is too hard to sleep and the air permeability is not good, so the bed should not be too hard.
Brown stretcher is not durable.
This kind of bed is a good choice in terms of breathability and softness. But when the bed is used for a long time, the elasticity will gradually weaken and become a soft bed. Therefore, this bed is not suitable for long-term use.
The wire spring bed is the worst.
The characteristics of this kind of bed are similar to those of brown stretch bed and soft bed. It may be comfortable to sleep at first, but it will be uncomfortable after a long time. It is not suitable for patients with spinal diseases such as cervical spondylosis.
Ideality kang
People in rural areas in the north often sleep on fire kang, which can keep warm in winter and cool down in summer. This is an ideal place to sleep. But lying directly on the kang is also very hard, so people put blankets and mattresses on it and then sleep comfortably. This is the most favorable "advanced bed" for patients with cervical spondylosis to sleep.
But there are no such "advanced beds" in many places. What should we do? The most ideal and economical way is to spread a mattress with suitable thickness and hardness or a thinner Simmons mattress on the wooden bed. What is the best degree of hardness? It is best to put your palm under your waist when lying on your back.
Some people may think that choosing a bed is a bit like choosing shoes. Only they know whether it is suitable or not. In fact, the two are different, because a comfortable bed is not necessarily good for your health. On the one hand, you should be comfortable. On the other hand, you should be healthy. You should have your cake and eat it.
