Evidence-based, independent, without hidden assumptions — clarity where your child's safety truly matters.
De WaterExpert is the public platform of Shiva de Winter — thirty years of swimming instruction, fourteen summers as a lifeguard, chair of the NSWZ. We do not sell fear or shortcuts. We explain what safety in and around water truly requires, evidence-based and honest, so that parents, organizations, and policymakers make better choices.
On a hot day, the call for more places to cool off makes perfect sense. But awareness and swimming skills carry more weight than concrete — otherwise we're just mopping the floor with the tap running.
