At what age can babies swim?

Babies can swim as soon as they are born. The earlier they are allowed to swim, the better, because the baby was soaked in amniotic fluid in the mother's belly. If the baby is allowed to swim after he is older, he will have forgotten the familiar water and may be afraid.

1. Promote the growth of baby's bones. During swimming, the baby strengthens the muscle activity of the whole body, especially the muscle activity of the limbs. The baby can easily make large movements in the water, such as sliding arms, bending legs and twisting waist, so as to promote the faster delivery of nutrients and oxygen in the blood to bones and muscle tissues, promote the increase of growth hormone levels in the body, thereby promoting bone growth and accelerating the growth rate of babies. Improve baby's heart function. Regular swimming can develop the myocardium, stimulate metabolism, and make the heartbeat slower and stronger than that of babies of the same age, which prepares the baby to bear a greater physical load.

2. Promote the development of infants' respiratory organs. Regular swimming can improve the function of the respiratory system. Due to the pressure of water on the thorax, the intercostal muscles are exercised, the alveolar ventilation is increased, and the pectoralis major and minor muscles are exercised and strengthened due to exercise. Improve baby's immunity. Babies who participate in swimming activities at an early age have been active in a water environment since childhood, which enhances the adaptability of their body temperature regulation function and therefore rarely suffer from colds. Breath-holding and diving exercises during swimming further promote the training and development of the respiratory function, thereby improving the baby's health level, immune ability and nervous system function.

3. Promote digestion and absorption. When the baby is swimming, the constant movement of the body and the impact of water waves will significantly increase the baby's insulin level, thereby increasing gastrointestinal motility, helping food digestion and absorption, thereby increasing appetite and more comprehensive absorption of nutrients. In addition, swimming will consume a certain amount of physical strength, so the baby sleeps better after swimming, which is conducive to establishing regular sleep.

4. Improve the sensitivity of sensory cells. When babies swim, the combined effects of multiple external factors such as water temperature, hydrostatic pressure, buoyancy and wave impact will cause a series of benign reactions in the baby's skin, joints, nervous system and endocrine system, strengthen the stimulation of the baby's sensory systems, and promote the rapid transmission of comprehensive information such as kinesthetic sense, taste, hearing, touch and balance, thereby improving reaction ability and promoting the coordinated cooperation of various organs to complete various movements.

5. Promote the development of brain nerves. The brain nerves are connected to the terminal nerves of various parts of the body. Therefore, when the baby performs free large-scale movements in the water, various movements are directly controlled and regulated by the nervous system, and the activities of muscles and joints in turn stimulate the cerebral cortex nerves, thereby promoting the rapid development of brain function and making the brain more responsive to movements.
