Drinking baking soda (sodium bicarbonate) water at night for 2 weeks is a popular natural remedy trend, but it’s important to understand both the potential benefits and risks. Here’s a clear, evidence-based breakdown:
🧪 What Is Baking Soda Water?
Baking soda (sodium bicarbonate) is an alkaline compound that neutralizes acid. A typical recipe is:
-
½ teaspoon baking soda
-
in 8 ounces (240 ml) of water
✅ Potential Benefits (Based on Limited Evidence)
| Potential Benefit | Explanation |
|---|---|
| Acid reflux relief | Neutralizes stomach acid, may reduce heartburn. |
| Alkalizes the body (myth vs. fact) | Slight temporary pH changes in urine, but doesn’t change blood pH. |
| Improved digestion | May help relieve occasional indigestion or bloating. |
| Kidney support (in early disease) | Some studies suggest bicarbonate slows kidney function decline in early-stage CKD. |
| Exercise recovery | May buffer lactic acid buildup (used by athletes in precise dosages). |
⚠️ Risks and Side Effects
-
Sodium overload
-
½ tsp contains ~630 mg sodium—can raise blood pressure if taken daily.
-
-
Alkalosis (serious)
-
Overuse may disrupt your blood’s acid-base balance → nausea, vomiting, confusion, or cramps.
-
-
Stomach issues
-
Gas, bloating, or even stomach rupture (rare) if taken with a large meal.
-
-
Kidney strain
-
Long-term use can affect kidney function in healthy individuals.
-
-
Drug interactions
-
May interfere with medications like aspirin, antibiotics, or diabetes drugs.

🕒 What Happens If You Drink It for 2 Weeks at Night?
| Day | Possible Effects |
|---|---|
| 1–3 | May reduce heartburn or mild indigestion |
| 4–7 | Body begins adjusting; sodium may affect blood pressure in sensitive individuals |
| 8–14 | Risk of sodium buildup or minor alkalosis if taken daily; benefits plateau |
✅ Recommendations
-
Safe use: Occasional use (1–2x/week) for heartburn may be fine for healthy adults.
-
Avoid daily long-term use without medical advice.
-
Talk to your doctor if you have high blood pressure, kidney disease, or are on medication.
