Water is essential for numerous physiological processes in the body. Dehydration occurs when the amount of water lost from the body is not replaced. Acute dehydration refers to a sudden, and often severe, loss of fluid, for example, during illness or due to excessive sweating. (source)
Dehydration can negatively affect nearly every physiological process. Specifically, it immediately hinders cardiovascular performance, negatively affecting nutrient and oxygen delivery and temperature regulation, resulting in decreased physical and cognitive performance. Maintaining balanced fluid levels ensures proper nutrient delivery and temperature regulation, promoting desired cognitive and physical performance.
Supplement with Electrolytes: Electrolyte supplementation has been shown to improve markers of dehydration. (source) Electrolytes, when consumed with water, are quickly absorbed in the small intestine, which aids in rapid rehydration. (source) Recommendation: Supplement with a variety of electrolytes with at least 500 mg of sodium daily.
Supplement with Taurine: Taurine is a key molecule that helps to maintain cellular water balance. (source, source) Through cellular accumulation, taurine regulates water balance in the cells, resulting in improved hydration status. (source, source) Recommendation: Supplement with at least 1 g of taurine daily.
