Most heartburn episodes can be relieved at home within minutes to hours using a combination of simple pantry items, body positioning, and habit changes. The burning sensation happens when stomach acid escapes upward into your esophagus, and nearly everything on this list works by either neutralizing that acid, keeping it where it belongs, or reducing the pressure that pushes it up.
Baking Soda for Fast Relief
The quickest home remedy is one you probably already have in your kitchen. Baking soda (sodium bicarbonate) directly neutralizes stomach acid on contact. Mix half a teaspoon into a full glass of water and drink it. You can repeat this every two hours if the burning returns, but don’t exceed five teaspoons in a single day. The relief is usually noticeable within minutes.
This works well as an occasional fix, but it’s not something to rely on daily. Baking soda is high in sodium, and frequent use can cause side effects like bloating, nausea, or electrolyte imbalances. Think of it as a fire extinguisher, not a smoke detector.
Change Your Position
Gravity is your most reliable tool against acid reflux. If you’re lying down when heartburn strikes, sitting or standing upright immediately reduces the amount of acid reaching your esophagus. Avoid bending over or slouching, which compresses your stomach and pushes acid upward.
If heartburn tends to hit at night, elevate the head of your bed rather than just stacking pillows (which can bend you at the waist and make things worse). A wedge pillow angled at 30 to 45 degrees, raising your head six to 12 inches, keeps your esophagus above your stomach while you sleep. Research from Amsterdam UMC also found that sleeping on your left side reduces reflux, because in that position your stomach sits below the junction with your esophagus, making it harder for acid to travel upward. Sleeping on your right side has the opposite effect.
Loosen What You’re Wearing
This one sounds too simple to matter, but tight waistbands have a surprisingly large effect. A study published in Gastroenterology found that a snug belt increased pressure inside the stomach by about 7 to 9 mmHg and made acid reflux roughly eight times worse. Even more striking, the belt slowed the esophagus’s ability to clear acid from a median of 23 seconds to over 81 seconds. That means acid sat in the esophagus nearly four times longer.
If you’re wearing fitted jeans, a tight belt, shapewear, or high-waisted pants when heartburn flares, switching to something loose can provide noticeable relief. This is especially worth considering after a large meal.
Chew Sugar-Free Gum
Chewing gum for 20 to 30 minutes after eating stimulates saliva production, and saliva naturally contains bicarbonate, the same acid-neutralizing compound in baking soda. The extra saliva washes acid back down from the esophagus and helps dissolve whatever remains. Bicarbonate gum (sometimes labeled as “dental” or “oral health” gum) is more effective than regular sugar-free varieties, but any sugar-free option helps. Avoid peppermint-flavored gum, though, since peppermint relaxes the valve between your stomach and esophagus.
Try Ginger
Ginger contains natural compounds that reduce irritation in the digestive tract and calm stomach spasms, which can slow the backflow of acid. The simplest method is ginger tea: peel and grate a small piece of fresh ginger root, steep it in hot water for five to ten minutes, and sip it slowly. You can also add grated ginger to soups or stir-fries.
About 4 grams total per day (a little less than an eighth of a cup of fresh ginger) is enough to help without overdoing it. More than that can actually irritate the stomach and worsen symptoms. Splitting the amount across two or three servings through the day works well.
Skip the Apple Cider Vinegar
Apple cider vinegar is one of the most popular heartburn remedies recommended online, but there is no published clinical evidence that it works. Harvard Health Publishing reviewed the claim directly and found zero studies in medical journals supporting its use for heartburn. Since vinegar is acidic, drinking it when your esophagus is already irritated by stomach acid risks making the burning worse, not better. Stick to remedies with a clearer track record.
Foods and Drinks That Make It Worse
Certain foods directly weaken the muscular valve at the top of your stomach (the lower esophageal sphincter), which is the gate that’s supposed to keep acid from escaping. Once it relaxes, acid flows upward more easily. The major culprits:
- Coffee and caffeinated drinks relax this valve, whether the coffee is regular or decaf.
- Chocolate contains a compound called methylxanthine, which is chemically similar to caffeine and has the same valve-relaxing effect.
- Peppermint, garlic, and onions all relax the valve and can trigger reflux even in small amounts.
- Fatty, fried, or very spicy foods both relax the valve and slow stomach emptying, giving acid more time and more opportunity to escape.
When heartburn is already active, avoiding all of these until symptoms fully resolve will keep you from refueling the problem. Eating smaller meals also helps because a full, distended stomach puts more pressure on that valve.
Habits That Prevent the Next Episode
Timing matters almost as much as what you eat. Lying down within two to three hours of a meal is one of the most common triggers for nighttime heartburn. Eating your last meal earlier in the evening, or at least staying upright afterward, gives your stomach time to empty before gravity stops working in your favor.
Eating slowly and chewing thoroughly reduces the amount of air you swallow, which decreases stomach distension. If you tend to eat large portions, splitting meals into smaller, more frequent ones keeps stomach volume lower and reduces upward pressure on the valve.
When Heartburn Might Not Be Heartburn
Heartburn and a heart attack can feel remarkably similar. Even experienced doctors sometimes can’t distinguish them based on symptoms alone. If you have persistent chest pain and you’re not certain it’s heartburn, call 911. This is especially important if the pain spreads to your jaw, neck, or arm, if you feel short of breath, or if you break into a cold sweat. Both heartburn and early heart attacks can produce pain that comes and goes, so the fact that it subsides temporarily doesn’t rule out something serious. If you’ve had an episode of unexplained chest pain that resolved on its own but you didn’t seek medical attention at the time, follow up with your doctor afterward.
