\n Patients, even those with no kidney stone issues, always ask me, \u201cHow much water should I drink?\u201d It\u2019s one of the most challenging questions to answer because there\u2019s no one-size-fits-all. As a urologist \u2014 and as a kidney stone patient in recovery, I stress this advice: The goal isn\u2019t ounces in, it\u2019s urine out. Here\u2019s what else to know about developing a healthy water habit.\n <\/p>\n
Water matters to your body<\/p>\n
\n Your body is about 60% water<\/a>. That fluid lives inside your cells, between them and in the bloodstream. It cushions organs and joints, carries essential nutrients and hormones, clears waste and helps keep your body temperature in check.\n <\/p>\n \n Water also works in conjunction with electrolytes, such as sodium, potassium and chloride. They help your muscles contract, your nerves fire and your blood pressure stay balanced. If water intake falls behind losses, electrolyte concentrations can shift. That\u2019s why dehydration can show up as muscle cramps, dizziness or even an irregular heartbeat.\n <\/p>\n \n When you\u2019re even mildly dehydrated \u2014 as I was that weekend \u2014 the body has to work harder to maintain balance. Blood becomes more concentrated, the heart must pump harder, and the brain feels the strain \u2014 fatigue, fuzzy thinking, slower reaction time. Digestion can also slow down since water helps move food through the gut.\n <\/p>\n \n On the flip side, overhydrating without enough sodium \u2014 especially during endurance exercise \u2014 can be just as dangerous. It dilutes sodium in the blood, which can lead to confusion, nausea and in extreme cases, seizures. That\u2019s why balance matters: Hydration is not just about water, but water and electrolytes working together.\n <\/p>\n \n Most people immediately freak out when I suggest about eight to 10 glasses of water a day. That\u2019s because they realize they\u2019re nowhere close. And to be honest, unless I\u2019m actively paying attention, I don\u2019t always hit that number either. That\u2019s OK. The truth is, some people need more, and some need less. And it can be harder to do when you\u2019re doing shift work or traveling or facing any other number of reasons.\n <\/p>\n \n The standard advice is about 3.7 liters or 125 ounces per day for most men and 2.7 liters or 92 ounces per day for most women \u2014 from all sources, not just glasses of water, according to the National Academy of Medicine<\/a>, formerly the Institute of Medicine. Roughly 20% of that typically comes from food. Think of these numbers as a starting point, not a hard limit.\n <\/p>\n \n Remember it\u2019s also how much urine you produce: Urology guidelines recommend<\/a> producing at least 2.5 liters of urine a day to lower stone recurrence.\n <\/p>\n \n Water needs depend on your body size, activity level, the climate you live in and even the medications you take. A one-size-fits-all number doesn\u2019t exist. That\u2019s why I like the simple \u201curine color check\u201d more than counting ounces.\n <\/p>\n \n Now look at your urine. Yes, really. Aim for pale yellow throughout the day. Medium to dark yellow usually means you\u2019re behind. Vitamins and some foods can change the shade, and your first pee of the morning will almost always be darker \u2014 that\u2019s normal.\n <\/p>\n \n If you want to go deeper into what urine color, clarity and even odor can reveal about your health, I wrote about it here<\/a>.\n <\/p>\n \n Some days call for more water: when it\u2019s hot or humid, you\u2019re doing a long workout, you have a fever, you\u2019re nauseous or have diarrhea, you\u2019re doing high-altitude travel or eating a salty meal.\n <\/p>\n \n In the heat, steady sipping is best \u2014 about 8 ounces every 15 to 20 minutes. Don\u2019t exceed 48 ounces (1.5 quarts) in an hour, or you risk dangerously low blood sodium. Think of this as a water marathon, not a sprint.\n <\/p>\n \n Hydration is important for urinary tract infection prevention in both men<\/a> and women. Want proof? In a randomized clinical trial<\/a> of premenopausal women prone to recurrent UTIs, those who increased their water intake by about 1.5 liters daily experienced 1.7 infections over a year, compared with 3.2 in the control group \u2014 a nearly 50% reduction. They also required fewer antibiotics (1.9 courses versus 3.6).\n <\/p>\n \n Overhydration \u2014 especially during endurance activities \u2014 can dangerously dilute blood sodium, a condition known as exercise-associated hyponatremia. Marathon runners collapsing at the finish line often drank too much plain water, not too little. If you\u2019re running long distances in the heat, combine water with salt \u2014 through sports drinks or salty foods.\n <\/p>\n \n If you have chronic conditions such as kidney disease or heart failure, be extra cautious. Your body might not handle large fluid loads well. In these cases, drinking excessive amounts can overload your system, causing swelling, shortness of breath or dangerous electrolyte imbalances. For these individuals, fluid intake goals should always be tailored with your doctor\u2019s guidance.\n <\/p>\n \n Plain water is ideal, but it\u2019s not the only way to meet your hydration needs. Coffee and tea count for regular caffeine consumers. In fact, controlled studies show that moderate coffee hydrates about as well as water. Alcohol does the opposite \u2014 drawing fluid out.\n <\/p>\n \n Regarding the many types of water at stores \u2014 alkaline, spring, reverse osmosis, \u201cstructured\u201d water \u2014 most are marketing gimmicks, not medical essentials. Your kidneys don\u2019t care if your water is from a mountain spring or your tap filtered at home. What matters is consistency, not branding. If a particular type encourages you to drink more because you like the taste, that\u2019s fine. But don\u2019t feel pressured to pay extra for gimmicks.\n <\/p>\n \n If plain water isn\u2019t your thing, add a squeeze of lemon or fruit slices. A few drops of flavor enhancers \u2014 such as squeezable sweeteners found in grocery aisles \u2014 can also make water more enjoyable. The best water is the one you will actually drink throughout the day.\n <\/p>\n \n For extended, sweaty activities, add electrolytes or salty foods to replace sodium along with water. For everyday life and moderate exercise, water plus a balanced diet is usually sufficient.\n <\/p>\n \n It\u2019s the same thinking with water bottles: The \u201cbest\u201d water bottle is the one you\u2019ll use. If a specific style or gadget encourages you to drink more, that\u2019s great. But don\u2019t let marketing convince you that the container matters more than the habit. Keep it simple \u2014 just drink.\n <\/p>\n \n For me, drinking water has to fit into my daily routine. Between surgeries, I grab a glass of water \u2014 if I have seven cases, that\u2019s seven built-in breaks to hydrate. In the clinic, I drink less because I\u2019m constantly moving between patients, but I make up for it during lunch and on the drive home. I also consume two to three protein shakes a day. They remind me that fluids come from more than just water bottles.\n <\/p>\n \n We often think about water only during emergencies \u2014 such as hurricanes or heat waves with empty store shelves. But the real success lies in making hydration a daily habit, not a panic-buying response.\n <\/p>\n \n Set a realistic baseline, monitor your urine, adjust as needed, and respect heat and activity-related limits. Simple, consistent habits keep you hydrated \u2014 and that\u2019s the plan I follow.\n <\/p>\n \n And yes \u2014 as I finish writing this, I\u2019m drinking from a water bottle I picked up at the CNN souvenir shop. Proof that sometimes, the best hydration plan is the one you\u2019ll stick with \u2014 even if it has a logo.\n <\/p>\n","protected":false},"excerpt":{"rendered":"Dr. Jamin Brahmbhatt is a urologist and robotic surgeon with Orlando Health and an assistant professor at the…\n","protected":false},"author":2,"featured_media":192827,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[61],"tags":[97,269],"class_list":{"0":"post-192826","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nutrition","8":"tag-health","9":"tag-nutrition"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/192826","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=192826"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/192826\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/192827"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=192826"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=192826"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=192826"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"If](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/09\/gettyimages-1319877889.jpg\")
