Plain water is the simplest and most effective drink for quick heartburn relief at home. It helps wash stomach acid back down from your esophagus and dilutes the acid sitting in your stomach. But water isn’t your only option. Several other drinks can calm that burning feeling, and a few popular ones can actually make it worse.
Why Water Works So Well
When you feel heartburn, stomach acid has splashed up into your esophagus, the tube connecting your throat to your stomach. A glass of water physically rinses that acid back down where it belongs. It also dilutes the acid concentration in your stomach, which reduces the irritation if more acid refluxes upward.
The key is how you drink it. Gulping down a large glass all at once can distend your stomach, which actually increases pressure on the valve between your stomach and esophagus and pushes more acid upward. Instead, take slow, steady sips. A half glass to a full glass of room-temperature water, sipped over a few minutes, is enough to clear acid from your esophagus without overfilling your stomach.
Alkaline Water for Stronger Relief
If regular water helps a little but not enough, alkaline water with a pH of 8.8 or higher offers a more targeted benefit. At that pH level, alkaline water permanently inactivates pepsin, a digestive enzyme that plays a central role in the damage caused by acid reflux. Pepsin becomes active in acidic conditions (below pH 4.6) and stays active as long as the environment remains acidic. Alkaline water neutralizes that environment.
Research published in the Annals of Otology, Rhinology & Laryngology found that pH 8.8 alkaline water had eight times the buffering capacity of conventional bottled water, meaning it took far more acid to bring the pH back down to levels where pepsin could reactivate. You can find alkaline water at most grocery stores. It won’t replace treatment for chronic reflux, but for occasional heartburn at home, it’s a step up from tap water.
Ginger Tea Speeds Digestion
Ginger tea is one of the better herbal options for heartburn because it addresses one of the underlying causes: food sitting in your stomach too long. Ginger promotes faster gastric emptying, meaning it helps move food from your stomach into your small intestine more quickly. Once food leaves your stomach, your stomach produces less acid. Less acid means less chance of it splashing upward into your esophagus.
To make ginger tea, slice a one-inch piece of fresh ginger root and steep it in hot water for 10 to 15 minutes. Drink it warm, not scalding. You can add a small amount of honey for taste. Avoid ginger ale as a substitute, since most commercial brands contain very little actual ginger and are carbonated, which can worsen reflux by introducing gas that increases stomach pressure.
Chamomile Tea as a Gentle Option
Chamomile tea contains anti-inflammatory compounds that may help soothe an irritated esophagus. It’s caffeine-free and mildly calming, which makes it a good choice for heartburn that flares up in the evening. There’s no strong clinical evidence that chamomile directly reduces stomach acid, but it doesn’t trigger reflux the way some other teas do, and its soothing properties make it a safe bet when you’re looking for something warm to drink.
One important distinction: chamomile is fine, but peppermint tea is not. Peppermint relaxes the lower esophageal sphincter, the muscle that keeps stomach acid from flowing upward. A relaxed sphincter means more reflux, not less. If you buy herbal tea blends, check the ingredients for mint or peppermint and skip those.
Baking Soda: Quick but Limited
Dissolving a small amount of baking soda (sodium bicarbonate) in water creates a basic solution that neutralizes stomach acid on contact. It works fast, often within minutes, and has been used as a home antacid for generations. MedlinePlus recommends dissolving the powder in at least 4 ounces of water and taking it one to two hours after meals.
There are real limits to this approach, though. Baking soda is high in sodium, so it’s a poor choice if you’re watching your salt intake or managing blood pressure. It should not be used for longer than two weeks at a stretch. And because it neutralizes acid so aggressively, your stomach may respond by producing even more acid afterward, a rebound effect that can leave you worse off than when you started. Think of baking soda water as an occasional rescue remedy, not a regular habit.
Drinks That Make Heartburn Worse
Several beverages that people reach for instinctively will actually intensify heartburn:
- Citrus juices. Orange juice and grapefruit juice are common heartburn triggers. Their high acidity irritates an already inflamed esophagus. If you want fruit juice, opt for something low-acid like watermelon or pear juice.
- Coffee and caffeinated tea. Caffeine relaxes the lower esophageal sphincter, the same problem as peppermint. Both regular and decaf coffee are mildly acidic, which compounds the issue.
- Carbonated drinks. The carbon dioxide in sparkling water, soda, and seltzer creates gas in your stomach, increasing internal pressure and pushing acid upward.
- Alcohol. It relaxes the esophageal sphincter, increases acid production, and irritates the esophageal lining. All three effects at once.
Skip the Apple Cider Vinegar
Apple cider vinegar is one of the most widely recommended home remedies for heartburn online, but there is no published clinical research supporting its use. Harvard Health Publishing reviewed the available evidence and found zero studies in medical journals testing apple cider vinegar for heartburn. The logic behind the recommendation, that adding acid helps digestion, contradicts what’s actually happening during a reflux episode. Your esophagus is already being damaged by acid. Adding more acid, even a “natural” one, is unlikely to help and could make the burning worse.
How You Drink Matters as Much as What
Even helpful beverages can backfire if you drink them the wrong way. Large volumes of any liquid consumed quickly during or right after a heavy meal can stretch the stomach and trigger reflux. The better approach is to take small sips during meals and drink most of your fluids between meals instead. Spreading your intake throughout the day keeps your stomach from overfilling at any one point.
Temperature matters too. Very hot drinks can irritate an already inflamed esophagus. Lukewarm or room-temperature liquids are gentler. If you’re having a nighttime flare, drink your water or tea at least 30 minutes before lying down, giving gravity time to help keep things moving in the right direction.
