Plenty of beverages hydrate you just as well as water, and some actually keep you hydrated longer. Milk, herbal teas, coconut water, broths, and even coffee all contribute to your daily fluid intake. About 20% of the water your body needs each day comes from food alone, and the rest can come from any combination of drinks, not just plain water.
The average healthy adult needs roughly 11.5 to 15.5 cups of total fluid per day from all sources. If you struggle to drink enough plain water, swapping in other hydrating options is a perfectly valid strategy.
Milk Hydrates Better Than Water
This surprises most people, but milk is one of the most effective hydrating beverages available. Its high concentration of sodium and potassium, combined with natural sugars and protein, helps your body absorb and retain fluid longer than plain water. Where water passes through your system relatively quickly, the energy density and composition of milk slow gastric emptying, giving your intestines more time to absorb the liquid.
Both whole and skim milk perform well for hydration. If you’re looking for a post-workout drink or something to sip throughout the day that genuinely keeps fluid in your body, milk is a top choice. The one caveat: its thickness and calorie content mean it’s not ideal for gulping large volumes at once, and some people experience stomach discomfort from drinking it quickly.
Herbal Tea Counts as Hydration
Caffeine-free herbal teas are essentially flavored water. Chamomile, peppermint, rooibos, hibiscus, and ginger teas all hydrate you in the same way plain water does, with zero diuretic effect. If you find water boring, keeping a pitcher of cooled herbal tea in the fridge or sipping warm cups throughout the day is one of the simplest swaps you can make.
You can also infuse plain water with fruit, cucumber, or fresh herbs like mint and basil. These aren’t technically teas, but they solve the same problem: making hydration more appealing without adding sugar or calories.
Coffee and Caffeinated Tea Still Hydrate You
The idea that coffee dehydrates you is largely a myth. Caffeine does have a mild diuretic effect, but it only becomes significant at high doses. Research published in Frontiers in Nutrition found that caffeine at about 3 mg per kilogram of body weight (roughly one to two standard cups of coffee for most adults) does not disturb fluid balance. Only at around 6 mg per kilogram, equivalent to roughly 537 mg of caffeine or five-plus cups, did researchers observe a meaningful increase in urine output.
For a typical coffee or black tea drinker having two to three cups a day, the fluid you take in far outweighs what caffeine causes you to lose. Your morning coffee counts toward your daily hydration total.
Coconut Water: A Natural Electrolyte Drink
Coconut water contains about 470 mg of potassium and 30 mg of sodium per cup, making it a solid source of the electrolytes your body uses to move fluid in and out of cells. It’s lower in sugar than most fruit juices and has a light, slightly sweet flavor that many people prefer to plain water.
That said, coconut water is relatively low in sodium compared to sports drinks. Sodium is the primary electrolyte that helps your body hold onto water, so coconut water works well for everyday hydration but may not fully replace what you lose during heavy, prolonged sweating. If you like the taste, it’s an excellent daily option. For intense exercise lasting more than 45 minutes, a drink with more sodium may serve you better.
Sports Drinks Have a Specific Use Case
Sports drinks were designed for athletes, not for sipping at a desk. Johns Hopkins Medicine recommends them specifically when exercise lasts more than 45 minutes for adults or more than an hour for kids. Below that threshold, water or any other hydrating beverage works fine.
The benefit of sports drinks is their combination of sodium, potassium, and sugar, which accelerates fluid absorption in the gut and replaces what you lose through sweat. But for everyday hydration, they add unnecessary sugar and calories. If you’re not exercising hard, you don’t need them.
Broth and Soup Work Surprisingly Well
Clear broths, whether chicken, beef, vegetable, or bone broth, are excellent for hydration because they combine fluid with sodium. Your body needs electrolytes to actually retain the water you drink. Without adequate sodium and potassium, drinking water alone may not fully hydrate your cells. Broth delivers both fluid and the minerals that help your body use it.
This is why broth is a go-to recommendation when someone is sick, recovering from a stomach bug, or dealing with dehydration. It’s warm, easy to consume, and replaces both fluid and electrolytes simultaneously. A cup of broth in the afternoon can be just as hydrating as a glass of water, and potentially more effective if your electrolyte levels are low.
Fruits and Vegetables Add Up
You don’t have to drink all your fluids. Many common foods are over 90% water by weight:
- Cucumbers: 96% water
- Watermelon: 92% water
- Strawberries: 92% water
Other high-water foods include celery, lettuce, zucchini, tomatoes, bell peppers, and oranges. Eating a salad, snacking on melon, or adding extra vegetables to meals all contribute to your daily fluid intake. Since food provides about 20% of the average person’s daily water needs, someone who eats plenty of fruits and vegetables is already getting a meaningful head start on hydration before drinking anything at all.
Drinks to Limit or Avoid for Hydration
Not all beverages are equally useful. Alcohol is a true diuretic that causes your body to lose more fluid than the drink provides, especially in higher concentrations like spirits and wine. Beer is less dehydrating due to its lower alcohol content and higher water volume, but it’s still a poor hydration choice overall.
Sugary sodas and energy drinks technically contain water, but their high sugar content can slow fluid absorption, and the calorie load makes them impractical as a primary hydration source. Diet sodas hydrate reasonably well from a pure fluid standpoint, but they offer none of the electrolytes or nutrients that make options like milk or coconut water genuinely useful.
Fruit juice hydrates effectively but comes with concentrated sugar. Diluting juice with water (roughly half and half) gives you flavor and some vitamins while cutting the sugar load significantly.
How to Tell if You’re Hydrated Enough
The simplest test is urine color. Pale yellow means you’re well hydrated. Dark yellow or amber means you need more fluids. Clear and colorless usually means you’re overhydrating, which isn’t dangerous for most people but isn’t necessary either.
Thirst is a reliable signal for healthy adults, though it becomes less accurate as you age. If you’re someone who forgets to drink, rotating between different beverages throughout the day, a coffee in the morning, herbal tea midday, broth with lunch, water-rich snacks in the afternoon, can make hitting your fluid needs feel effortless without forcing yourself to drink plain water you don’t enjoy.
