When you’re nauseous, the key is to take in water slowly, in very small amounts, and as cold as possible. Gulping even a few ounces at once can trigger vomiting or make nausea worse. The goal is to get fluid into your body without overwhelming your stomach, and the technique matters more than the type of water you drink.
Start With Ice Chips, Not a Glass of Water
Ice-cold water and crushed ice help ease nausea more effectively than room-temperature or warm water, particularly when motion sickness or an upset stomach is involved. If you can’t imagine taking a sip of anything, start with ice chips. Let them melt on your tongue rather than chewing and swallowing them. This delivers a tiny, controlled amount of water with each chip, and the cold itself has a calming effect on the stomach.
Once you can handle ice chips without your nausea getting worse, move to small sips of cold water. Keep a glass nearby and take one sip every 10 to 15 minutes rather than drinking continuously.
How Much to Sip and How Often
The volumes here are smaller than most people expect. Start with about one teaspoon (5 ml) to one tablespoon (15 ml) at a time. If that stays down without worsening your nausea, gradually increase the amount over the next hour or two. The pattern is: tiny sip, wait 10 to 15 minutes, another tiny sip, wait again. If you tolerate that for 30 to 60 minutes, you can start taking slightly larger sips or sipping a bit more frequently.
This feels painfully slow when you’re thirsty, but it works. Your stomach is far more likely to accept a teaspoon of water every few minutes than two ounces all at once. Patience with the process is what keeps the fluid in your body instead of bringing it back up.
If You’ve Already Vomited
After throwing up, resist the urge to immediately drink water. Give your stomach a break of at least a couple of hours before trying to rehydrate. When you do start, go back to the beginning: ice chips first, then small sips of water every 15 minutes. Your stomach lining is irritated after vomiting, and flooding it with liquid too soon often triggers another round.
The Cleveland Clinic recommends this grace period specifically because the stomach needs time to settle before it can absorb anything. Skipping this step is one of the most common mistakes people make, and it creates a frustrating cycle of drinking, vomiting, and becoming more dehydrated.
What to Add to Your Water
Plain water works fine for mild nausea, but if you’ve been vomiting or have diarrhea, you’re losing electrolytes along with fluid. Replacing those helps your body absorb the water more efficiently. You can buy oral rehydration solutions at any pharmacy, or make a basic version at home: mix 3/8 teaspoon of salt, 1/4 teaspoon of salt substitute (potassium chloride), 1/2 teaspoon of baking soda, and about 2.5 tablespoons of sugar into one liter of tap water. This follows the World Health Organization’s formula and provides the glucose-to-salt ratio your intestines need to pull water into your bloodstream.
Ginger is another worthwhile addition. Research on pregnant women with nausea found that 250 mg of ginger taken four times a day significantly reduced nausea and vomiting in multiple clinical trials. You don’t need capsules to get this benefit. Steep a thumb-sized piece of fresh ginger in hot water, let it cool until it’s cold, and sip it the same way you’d sip plain water. The total daily amount used in studies ranged from about 1,000 to 1,500 mg, which is roughly equivalent to a teaspoon of grated fresh ginger spread across the day.
Skip the Straw
Drinking through a straw pulls air into your digestive tract along with the liquid. That extra air causes bloating and gas, both of which make nausea worse. Sip directly from a cup or glass instead. If you’re lying down and a cup feels awkward, a small squeeze bottle or even a spoon gives you better control over volume without introducing air.
Positions That Help
How you sit while drinking matters. Stay upright or slightly reclined rather than lying flat. Gravity helps liquid move down through your stomach, and lying flat can increase the sensation of fullness that worsens nausea. If you need to lie down, prop yourself up at about a 30-degree angle and take your sips in that position. Avoid drinking while fully reclined on your back.
Some people find it easier to tolerate water if they take slow, deep breaths through the nose between sips. This activates the body’s calming response and can reduce the wave-like sensation of nausea enough to get liquid down.
Signs You Need More Than Water
Mild dehydration can be managed at home with the sipping approach described above. You should start feeling noticeably better within 5 to 10 minutes of getting some fluid in. But if your mouth stays dry, you feel dizzy when standing, your urine is dark yellow or absent, or you can’t keep even small sips down for several hours, oral rehydration may not be enough. Moderate dehydration typically requires IV fluids, which means a trip to urgent care or the emergency room.
Children and older adults reach dangerous dehydration levels faster than healthy adults. For a young child who can’t keep fluids down, use a dropper or syringe to place tiny amounts of liquid (as little as 5 ml) into the mouth every 5 to 15 minutes. If even that comes back up repeatedly, seek medical attention rather than continuing to wait it out.
