Hydration strategies can vary significantly depending on the activity. For low-intensity exercises, like walking, minimal hydration might suffice. However, during high-intensity workouts or extended sessions, such as marathons, electrolyte-replenishing drinks may be necessary. The duration and intensity of the activity dictate fluid needs; therefore, athletes should assess their hydration pre-, during, and post-exercise. Moreover, environmental conditions, like heat and humidity, can influence hydration requirements. Overall, proper hydration is critical for performance and recovery.
