Marcelo Vieira da Silva Junier is a Brazilian footballer born on 12 May 1988 in Rio de Janeiro and is a member of the Brazilian national team. In the early morning of June 28, Beijing time, in the third round of the Group Stage of the World Cup in Russia, in the match between Brazil and Serbia, Marcelo was replaced by Felipe due to injury shortly after the opening.
After the examination, there was no major problem, and the Brazilian team doctor said that the back cramps may be related to the softness of the hotel bed.
So the question is, which type of bed is suitable for rest?
Soft bed, the largest body support area, lack of sufficient support, waist and hips appear slightly falling phenomenon, so that the spine can not maintain normal physiological curvature, muscles are also not well relaxed, easy to cause waist soreness.
Hard board bed, body support area is too small, the distribution of support force is uneven, the main force point is more discrete, the pressure on the shoulder blades and hips is large, but the waist lacks support, and even the phenomenon of waist suspension, which not only can not play a role in protecting the spine, the muscles can not be better relaxed, and because of long-term muscle tension and contraction, it is easy to lead to muscle fatigue, soreness, and long-term strain. In addition, excessive pressure can affect blood circulation at the stressed site, leading to local swelling and discomfort.
Medium hardness of the bed, such as a spring bed, the body contact area is also moderate body support area, the distribution of support force is relatively uniform, the mattress has sufficient support for the waist, which can play a full supporting role, but also maintain a good back physiological curvature, play a role in protecting the spine, so that the back muscles are fully relaxed and get full comfort.
Therefore, in the type of bed you choose, be prepared and choose a bed that suits you.
