Swimming is a sport that can exercise the body, but also to develop the child’s strong will, and even from a young age, infant swimming training is one of the effective ways to develop the intelligence of infants. 1, all the complex movements of swimming are completed by the brain domination, in the long period of swimming process can improve the brain function. Therefore, the brain responds quickly to the external environment, the infant intelligence development is good. 2, regular swimming can also make the heart muscle developed, so that the body’s metabolism is strong, the heartbeat is slower and stronger than children of the same age, which prepares the conditions for taking on a greater physical and intellectual burden. 3, infants need to overcome the pressure of water to breathe in the water, the breathing amplitude is large, holding the breath for a long time, so the function of the respiratory system is also improved, and the brain will be better regulated. There are more ways to promote infant growth and development, but learning to swim is also a very important way to start in infancy. The fetus grows for 9 months while swimming in amniotic fluid, so it has the ability to float and exclude air for some time after birth. So how to help your child train to swim? 1, newborn: the child is a natural swimmer, the newborn suddenly into the water, he is not afraid at all, in the water as usual very natural open eyes, but also on the surface of the water themselves floating swimming. 2, full-term infants: at this time, if the infant, by the pediatrician and neurologist check the physical and mental condition, you can swim. At first, they can swim in the bathtub, and the first time the water temperature is better at 36-37℃, and later it can be gradually reduced to 29-30℃. Practice for 5 to 40 minutes each time, and gradually extend the time. Before swimming should be given to the child to do massage or gymnastics. 3, after the age of half a child: under the protection or assistance of the mother, the baby can float or dive. After a period of exercise at home, after the age of half can be brought to the pool by adults to exercise. To keep the infant’s swimming ability throughout life, this training should continue for 2 to 3 years. In the process of infant swimming training, if interrupted for a month or two, he may lose the ability that has been acquired. Gradually extending the number of dives in the water is essential for the success of infant swimming exercises. Infancy is the golden period of a person’s life when his body is growing vigorously, and learning to swim is beneficial to his physical and intellectual development.
