Brief voluntary or incidental submersion may be included in lessons under the guidance of the teacher and at the discretion of the accompanying adult. Neither forced nor prolonged submersions are recommended.
The forced submersion of young babies is not recommended by the ASA, a position fully supported by the Royal Society for the Prevention of Accidents (ROSPA). It has been suggested that young babies have a natural breathing reflex, which will prevent them from attempting to breathe underwater. This view point is not universally accepted within the medical profession and attempting to breathe underwater can lead to water intoxication (hyponatremia) caused by the young baby swallowing large quantities of water, the result of which can adversely affect the electrolyte levels of the baby.
