                                The US National Academies of Sciences, Engineering, and Medicine recommend an average daily fluid intake of 2.7 liters for women and 3.7 liters for men, but this includes fluids from all sources, including food. To determine how many 750ml bottles you should drink a day, it's essential to consider your individual body weight, activity level, and climate.
