Hydration solutions are fluids designed to replenish lost body fluids and electrolytes, which are essential for maintaining proper bodily functions. These solutions are often used in medical settings to treat dehydration caused by illnesses, excessive sweating, or intense physical activity. Common types include oral rehydration solutions (ORS) and intravenous (IV) fluids. Oral rehydration solutions typically contain a balanced mix of water, salts, and sugars, making them effective for mild to moderate dehydration. In contrast, intravenous fluids are administered directly into the bloodstream and are used for more severe cases. Both types help restore hydration and support recovery in individuals, especially children and athletes.
