It is harmful. If the nerve that controls the muscle stretching function is damaged, the baby's muscle tension will change and abnormal behavior will occur. For a baby with high muscle tension, when we bend or stretch the baby's limbs, we can obviously feel the resistance increase, and the muscle joints are difficult to be pulled. If you stretch a little harder, the baby will feel pain and cry. ?

It should be noted that so far, there is no instrument that can accurately judge the muscle tension of infants. We can observe your baby's muscle tension by observing his life behavior, or rely on the doctor's feeling and experience to judge whether your baby's muscle tension is too high. So, what is the performance of the baby's high muscle tension? ?

First of all, babies with high muscle tension will make abnormal postures, such as straight legs, adduction crossing, scissors and so on. This is also a typical manifestation of the increase in muscle tension when a baby swims. Secondly, children with high muscle tension tend to be noisy, like crying, and it is difficult to fall asleep, and it is difficult to open their fists when taking a shower. Third, when the baby with high muscle tension takes a bath or swims, when the lower limbs enter the bathtub or the water surface, even if the parents intervene, the child is standing stiffly all over. ?

Fourth, when children with high muscle tension stand, they will not touch the ground with their toes first, and then gradually flatten out like normal children. On the contrary, they are always lame, even if you press them with your hand, you may not be able to crush their feet. Fifth, babies with high muscle tension tend to have tight muscles and relatively stiff postures. For example, when changing diapers for children, normal children's legs can be opened at 120 degrees, but babies with excessive muscle tension cannot be opened. If the child's muscle tone is still too high after six months, manual intervention is needed. So, what methods can reduce the baby's muscle tension? ?

For the way to relieve the baby's high muscle tension, most parents first think of teaching their baby to swim. Baby swimming can not only enhance the flexibility of baby's bones and muscles, but also reduce baby's muscle tension. At the same time, it can also promote the baby's transmission and perception of comprehensive information and promote the baby's healthy growth. It is worth mentioning that in addition to teaching your baby to swim, massaging your baby can also effectively relieve your baby's muscle tension! It is found that in the critical period of infant brain development, properly stimulating brain cells and nervous system can not only promote the development of infant nervous system, improve the body's immunity, enhance the infant's disease resistance and reduce the infant's muscle tension.
