We’ve all heard the age-old advice that drinking eight glasses of water a day is the golden rule for good health. It’s simple, easy to remember, and widely repeated, but is it really true? The truth is, hydration is not a one-size-fits-all formula. Factors like age, body size, activity level, diet, and even the weather all play a role in determining how much fluid your body actually needs. Whereas water is irrefutably beneficial for all-around well-being, the concept of an absolute quota to drink each day is a myth, not science.
Medical professionals and health professionals currently stress paying attention to your body rather than strictly adhering to the "8-glass rule." Thirst, urine output, and a person's lifestyle are usually more reliable measures of hydration than one-size-fits-all. And, besides plain water, hydration also comes from foods such as fruits, vegetables, and even from drinks like tea and milk. In conversation with The Daily Jagran, Dr. Shabana Parvee, Clinical Nutritionist, Artemis Hospitals, debunks hydration myths and presents the facts.
Myths vs Facts: Hydration
Myth 1: Everyone Needs Exactly 8 Glasses Of Water A Day
Fact: This is the most common myth about staying hydrated. In reality, there isn't a rule that works for everyone. Dr. Shabana Parvee mentions, “The amount of water you need depends on what size you are, how much you move, what you eat, and even the weather.” Some people may need more fluids than others, like those who work out a lot or live in hot places. Keep in mind that you can get your daily hydration from more than just plain water. Foods and drinks like fruits, vegetables, tea, and milk also help.
Myth 2: Only Plain Water Counts
Fact: You don't have to drink only water to stay hydrated. Soups, fruits, vegetables, tea, and milk are all good sources of fluids. Cucumbers and watermelons, for example, are almost 90% water. You can get your daily hydration from more than just plain water.
Myth 3: If You Are Thirsty, You Are Already Dehydrated
Fact Your body naturally tells you to drink when you are thirsty. Dr. Shabana Parvee states, “It is true that being very thirsty can be harmful for you, but it doesn't always mean you are in danger. That is just your body telling you to drink more water.”

Myth 4: More Water Equals More Detox
Regular hydration is helpful for your body, but the kidneys do the real detox work. Drinking extra water won't super cleanse you, balance is what really keeps you well.
