The Science behind Submersion

(please note you do not have to do submersion with your child,
 but it is a nice experience you can share)

 

 

Babies are born with many reflexes (an involuntary muscle reaction to an external stimulation).

These reflexes help the baby develop and learn voluntary muscle actions. As a baby develops, the newborn reflexes slowly disappear as they are replaced by the baby's own voluntary actions. We can use some of these newborns reflexes to help develop learned actions in the water environment.

There are 4 main reflexes linked to baby swimming.

  • Breath Holding Response

This reflex works in conjunction with the Gag reflex and the Mammalian Dive reflex. When the baby's face is blown on or water splashes it, they will hold their breath. The breath holding response usually stays with us, although it fades and can be over-ridden by adults.

  • Gag Reflex

If water gets into a baby's mouth the Gag reflex is stimulated. The baby's glottis and epiglottis goes into a spasm. This then creates a watertight seal over the windpipe. This seal prevents any of the water from entering the baby's lungs. This does not, however, close the oesophagus, which leads to the stomach, so the baby may still swallow the water that is entering their mouth. This reflex is active whilst the baby is feeding to stop them from choking as they continually swallow. Although they do not physically gag, the epiglottis forms the seal over the windpipe, but because in babies it is slightly elongated it meets the soft palate when closing. As the baby grows the epiglottis shortens and this then means that when the epiglottis closes, it closes entry from both the nose and the mouth at the same time. There is no definite decision as to when this reflex disappears and turns into a learnt action, it may vary greatly from baby to baby.

  • Amphibian Reflex

When a baby is in water or held horizontally above a surface, face downwards, they appear to start a swimming type of action. This is a bending of their torso along with rhythmic movements of the arms and legs. This movement can have the effect of propelling the baby through the water for a short distance, and looks as though they are actually swimming. However the baby is unable to lift their head from the water to breathe by themselves, hence the link to the Mammalian dive reflex and the breath holding response. The Amphibian reflex will usually have disappeared by the time the baby is approximately 6 months old.

  • Mammalian Dive Reflex

When the baby's face comes into contact with the water the body automatically reacts to protect the major organs, especially the heart and the brain. The heart rate slows down, blood is redistributed to the major organs from the extremities starting with fingers and toes and then possibly the arms and legs, to conserve these organs. The Mammalian dive reflex will not usually disappear, however it is strongest up to 2 years of age. We practice gentle, controlled submersions in order not to stimulate this reflex.

Babies who are taken swimming prior to 6 months of age, can be submerged and the breath holding response, diving reflex along with the Gag reflex will ensure that they hold their breath whilst submerged. Their breath holding abilities need to be taken into account, as babies breathe at a more rapid rate than adults they should not be submerged for too long (3 seconds max) to start with, however, these can be gradually increased with practice as their breath holding ability increases.

We use a cue to help the grown ups relax and ensure that they do not hesitate and send the baby the wrong signals.

When submerging a baby under 6 months old, the adult holding them will also probably be aware of the Amphibian reflex. The baby will feel like they are kicking towards the surface, their whole body may give a little flick too, lift their head from the water to breathe by themselves, hence the link to the Mammalian dive reflex and the breath holding response. The Amphibian reflex will usually have disappeared by the time the baby is approx 6 months old.

When submerging a baby at any time we need to be positive and hold them as gently and lightly as possible. The movement should be slow, rhythmical and most of all not at all jerky. Think of them as a little egg. When they come up out of the water, we gently and rhythmically sway them in the water from side to side, we praise them, tell them how well they have done in a positive manner with a happy face.

We don't immediately cuddle them, as this gives them a sign that they have been rescued from something bad, no matter how they naturally reacted to the submersion. If babies are submerged in the correct way then they can truly enjoy time in the water both above the surface and below, and soon you will find that most of them are more than happy to submerge themselves.

  • An Important point that we must always remember

Is that we need to supervise the baby at all times whilst in the pool, it only takes a moments distraction for accidents to happen, so, as the responsible adult you need to remain alert and concentrate on you baby at all times, Never, Never take anything for granted.
