Water is the best and most accessible option for staying hydrated. However, you can also include other fluids like coconut water, buttermilk, and fresh fruit juices, which provide essential electrolytes. Avoid sugary sodas and caffeinated beverages, as they can contribute to dehydration. Traditional Indian drinks like nimbu pani (lemon water) and aam panna (raw mango drink) are excellent choices for replenishing lost fluids and electrolytes.
