How Much Water You Should Drink Daily According to Experts

Urologist Jamin Brahmbatt challenges standard water intake advice, emphasizing that urine output matters more than rigid drinking quotas. Your ideal water consumption depends on body size, activity level, and climate. Thirst remains the most reliable hydration indicator for healthy adults.

How much water should you actually drink each day? The recommendations often conflict. Some suggest one glass with every meal. Others insist on two liters daily.

Urologist Jamin Brahmbhatt from Orlando Health challenges common advice. He says water intake is only half the solution for good health. What matters more is how much water leaves your body.

Brahmbatt recommends producing at least 2.5 liters of urine daily. This doesn't mean you should suddenly gulp water to increase bathroom breaks. He emphasizes finding the right balance.

Your water needs depend on several factors. Body size, activity level, and local climate all play roles. Some people need more water than others, according to CNN reporting.

So how can you tell when you need water? Brahmbatt suggests listening to your body's signals. Thirst remains the most reliable indicator for most healthy adults.

The eight-glasses-a-day rule lacks scientific backing. Many foods contain substantial water content too. Fruits, vegetables, and other beverages all contribute to hydration.

This practical approach makes more sense than rigid water quotas. It accounts for individual differences and prevents unnecessary water consumption.

Why do experts keep pushing specific water amounts then? Some recommendations may stem from bottled water marketing rather than medical evidence.
