Be careful as an athlete - pure water reduces rehydration
A study of shows: Rehydration after a activity works better if a drink containing sodium - i.e. a sports drink - is taken in combination with a standard meal. The simple consumption of a meal with tap water without electrolytes leads to a worse rehydration. An important aspect in training camps, in high altitude as well as in high-intensity phases during heat periods!
