                                According to the World Health Organization and UNICEF, reducing the osmolarity of oral rehydration solution (ORS) has lowered stool volume by 25% and the need for intravenous therapy by 30% in children. Understanding what is the tonicity of ORS and why its formulation has evolved is crucial for appreciating its life-saving effectiveness in treating dehydration.
