Watermelon (Citrullus lanatus) is commonly used to help alleviate dehydration, and this use is supported by scientific evidence. Watermelon is composed of about 90-92% water, making it one of the most hydrating fruits available. Studies have shown that foods with high water content can contribute significantly to total fluid intake and help maintain hydration status, especially in hot climates or after physical activity. In addition to its high water content, watermelon contains electrolytes such as potassium and magnesium, which are important for fluid balance in the body.

A 2013 study published in the Journal of Agricultural and Food Chemistry highlighted the hydrating properties of watermelon, noting its potential to replenish fluids lost during exercise. The fruit's natural sugars and small amounts of salt also aid in absorption and retention of water, similar to the mechanism of oral rehydration solutions. While watermelon alone may not replace severe fluid losses (as from vomiting or diarrhea), it can be a helpful, palatable adjunct for mild dehydration or as part of a regular diet to maintain hydration.

In summary, the use of watermelon to support hydration is grounded in science, based primarily on its high water content and electrolyte composition. However, more controlled clinical trials are needed to define its precise role in treating clinical dehydration compared to standard medical interventions.
