To replenish water and electrolytes, some athletes are thinking beyond the water bottle. Coconut water and pickle juice are now a thing, but do they actually offer any benefits over water or sports drinks? You can find one answer here: “Coconut Water Isn’t Hydrating You as Much as You Think.” The story notes that the popular drink has a key flaw: it supplies plenty of potassium, but it’s lacking in sodium – the main electrolyte you lose in sweat. One simple fix is to add a pinch of table salt to your bottle. Speaking of salty solutions, some athletes swear by brine, but “Does Drinking Pickle Juice Actually Help with Muscle Cramps?” While pickle juice is rich in sodium and contains some potassium, it is not a research-backed remedy for cramps. Even still, the article notes it’s used by high-profile athletes like Tennis champion Carlos Alcaraz and members of the Philadelphia Eagles. Your beverage isn’t the only way to replenish lost sweat, and some foods are especially helpful on a hot day: “15 foods that help you stay hydrated.” Fruits and vegetables can be excellent sources of rehydration, since some offer more than 92% water content to your diet, including cucumbers (96%), tomatoes (94%), spinach (92%), and watermelon (92%).
