Pregnant women need 8 to 12 cups of water a day, a significant jump from the usual recommendation. That’s roughly 64 to 96 ounces. If you’re struggling to hit that target, you’re not alone. Between nausea, a shrinking stomach, and constant bathroom trips, drinking enough water can feel like a full-time job. The good news is that a few simple adjustments to how, when, and what you drink can make a real difference.
Why Your Body Needs So Much More Water
During pregnancy, your blood plasma volume increases by about 50% over its non-pregnant level. Most of that expansion happens between the end of the first trimester and about 34 to 36 weeks. Your body is building an entirely new circulatory supply line to support the placenta and your growing baby, and water is the raw material.
Hydration also directly affects the fluid surrounding your baby. A meta-analysis published in PLOS ONE found that drinking more water measurably increased amniotic fluid volume, particularly in women who had been diagnosed with low levels. The improvement was time-dependent, meaning consistent daily intake over at least two weeks mattered more than chugging a large amount in a single day. In other words, steady habits beat occasional big efforts.
How to Handle Nausea and Still Stay Hydrated
First-trimester nausea creates a frustrating cycle: dehydration makes nausea worse, and nausea makes it harder to drink. Breaking the cycle usually means changing the form of the water rather than forcing yourself to gulp from a glass.
- Go cold. The colder the drink, the easier it tends to go down when you’re feeling sick. Freeze water or fruit juice into ice cubes and suck on them throughout the day.
- Sip, don’t chug. Small, frequent sips are far easier on a queasy stomach than drinking a full glass at once. Keep a bottle within arm’s reach so you can take a sip every few minutes without thinking about it.
- Add ginger. A slice of raw ginger in cold water or tea can help settle your stomach while you hydrate.
- Try flavor. If plain water triggers nausea, adding a splash of apple cider vinegar and honey, or squeezing in citrus, can make it more tolerable. Some women find flat lemon-lime soda easier to keep down during the worst waves.
Front-Load Your Fluids Earlier in the Day
One of the biggest complaints during pregnancy is waking up multiple times a night to pee. The instinct is to stop drinking in the evening, and that’s partly right, but research on nighttime urination found something surprising: tapering fluids at night alone didn’t solve the problem nearly as well as spreading intake more evenly during earlier hours. The total volume you drink during the daytime was a stronger predictor of nighttime bathroom trips than how much you drank right before bed.
A practical approach is to aim for most of your 8 to 12 cups between waking up and late afternoon. Start with a full glass first thing in the morning, drink steadily through lunch, and then slow your pace after dinner. You don’t need to cut yourself off entirely in the evening, just shift the balance so you’re not playing catch-up at 9 p.m.
Eat Your Water
You don’t have to get every ounce from a glass. Many fruits and vegetables are over 90% water, and they count toward your daily total. Cucumbers top the list at 96% water, followed by celery at 95%. Tomatoes and zucchini come in at 94%. Watermelon, strawberries, broccoli, and bell peppers are all around 92%.
Keeping sliced cucumbers or watermelon chunks in the fridge gives you a grab-and-go option that also delivers vitamins and fiber. Soups and smoothies work the same way. A bowl of broth-based soup at lunch or a frozen fruit smoothie in the afternoon can add a cup or two to your total without requiring you to drink another glass of plain water.
Make It a Habit, Not a Task
The women who stay well-hydrated during pregnancy almost always have a system rather than relying on willpower. A few strategies that work:
- Use a marked water bottle. A bottle with time markers (or even tape and a pen) gives you a visual target so you can see whether you’re on pace by mid-morning.
- Pair drinking with something you already do. Take a few sips every time you sit down, every time you check your phone, or every time you use the bathroom. Tying hydration to an existing habit removes the need to remember.
- Keep water everywhere. A glass on the nightstand, a bottle in the car, a cup at your desk. Proximity matters more than motivation.
Flavor fatigue is real. If you’re bored of plain water by week 20, rotate between infused water (cucumber-mint, strawberry-basil, lemon), herbal teas, and coconut water to keep things interesting.
Electrolyte Drinks and What to Watch For
Electrolyte drinks are generally fine during pregnancy, and they can be especially helpful if you’re losing fluids through vomiting. The key is choosing options that are low in added sugar and free from artificial sweeteners or additives. Many sports drinks contain more sugar per serving than you need. Look for low-sugar versions, or make your own by adding a pinch of salt and a squeeze of citrus to water.
Coconut water is a natural alternative that provides potassium and is typically lower in sugar than commercial sports drinks, though sugar content varies by brand.
Signs You’re Not Drinking Enough
Your urine color is the simplest daily check. You’re aiming for pale, clear yellow. Dark yellow urine with a strong smell means you need more fluids. Other signs of dehydration include feeling unusually tired, dizziness when you stand up, a dry mouth, and peeing less frequently than usual. During pregnancy, these symptoms can overlap with normal pregnancy fatigue, so urine color is the most reliable indicator to watch on your own.
Persistent dizziness, a rapid heart rate, or confusion are signs of more serious dehydration that need prompt medical attention. If you’re unable to keep any fluids down for an extended period due to severe nausea, that also warrants a call to your provider, since prolonged vomiting can lead to dehydration faster than most people expect.
