Develop bone and muscle coordination.
Human bodies in water are effortlessly buoyant, but meet some resistance during movement. By swimming and kicking in the water, a baby learns to control his or her muscles. This in turn improves physical coordination and balance, while developing the muscular and skeletal systems. With regular swimming, the baby grows stronger.
Strengthen the respiratory and circulatory systems.
Any exertion of energy boosts one's heart rate and creates a demand for more oxygen in the blood. While your baby plays in the water, the increased exertion from kicking and moving around strengthens his or her heart and builds lung capacity.
Builds the immune system.
All the splashing and kicking around drives your baby's core temperature higher and pumps blood throughout the body faster. This boosts the immune system. Not only are white blood cells, the body's defense mechanisms, able to find germs faster, but the slightly warmer temperature could kill some weaker bacteria before they have a chance to attack. This could result in less colds and less allergies. Additionally, the buoyant feeling from floating is proven to be a great stress-reducer, which helps keep stress hormones balanced.
Stimulate brain development.
When your baby moves around, the increased heart rate and breathing brings more oxygen to the brain. Released hormones make their way to the brain as well, all helping to nourish brain cells and build new neuron connections. Your baby will better respond to stimuli and possibly learn more things quickly.
Increase appetite and digestion
All that moving around can make anyone hungry, especially your baby. After eating wholesome, nutritious food your baby's digestive system will more readily absorb the valuable nutrients, thanks to increased secretion of digestive hormones.
Swimming, like many physical activities, uses plenty of pent up energy. Your baby will be worn out even after a short swimming session, allowing him or her to fall asleep soundly. You'll notice with regular swimming your baby will sleep deeper through the night. A regular sleep cycle is cause for celebration for parents and babies alike.
Promote sensory recognition.
Babies are in the stage of exploration. They still are discovering the world and what their bodies can do. Floating in a body of water adds another dimension to that exploration, not only in their muscle movements, but by stimulating most of the senses. They can touch the wet water versus the dry air, smell bubbles in the tub or chorine in a pool, see their toys, and hear their splashing. Every floating session is another opportunity to explore!
Allow for parent-child bonding.
Spending time swimming together naturally creates a bond between parents and children. The emotional attachment remains intact even as children gain more confidence. Swimming infants will find themselves capable of being without a parent's support, which is important to deter separation anxiety as children grow older.
