To stay hydrated, drink plenty of water throughout the day, even if you don't feel thirsty. Carry a reusable water bottle to ensure you have access to water at all times. Include hydrating foods like watermelon, cucumber, and oranges in your diet. Avoid excessive consumption of caffeinated or sugary drinks, as they can lead to dehydration. Coconut water and buttermilk are excellent natural alternatives to replenish electrolytes lost through sweat.
