Adolescent's body is in the stage of growth and development, bone is soft, especially spine (commonly known as the spine), until twenty years to complete ossification. Prior to this, if for some reason long crooked, and want to correct it, it is very difficult. The spine is the body's "beam", like axis and pillar, is human body limbs hub, with support for features such as weight and pressure. If the spine is crooked, it will sit straight, stand not straight. Therefore, young people to protect the spine, for the growth and development of the body and the body has a very important relationship.
Some teenagers love to sleep on the couch, that is comfortable, but they do not know that this is very harmful to the growth and development of the body. Because I slept in the rich elastic on the sofa bed, subsidence in some places, some local uplift, rugged, make the body lose the norm, regardless of the supine and lateral spine are in not normal bending state. Sleep on the sofa bed will make the muscles of the body on both sides of the elastic, some muscle and nerve will be squeezed, a long time can have lumbago.
Teenagers usually sleep in 10 - 8 hours or so, so long time has been sleeping on the couch, but also may cause excessive growth of bone collagen. Under normal circumstances, the collagen can make the muscle tissue to maintain a certain flexibility. Too much bone glue original not only of nerves, blood vessels and lymph tube caused by a large compression and muscle soreness and atrophy, cause damage to the body health and shape. Therefore, the best young people still sleep Banchuang or brown bed.
