Understanding Alkaline Water and pH
Alkaline water is simply water with a pH level higher than that of standard drinking water. The pH scale ranges from 0 to 14, where 7 is neutral. A pH below 7 is considered acidic, while a pH above 7 is alkaline. Most tap water has a neutral pH of around 7. Naturally occurring alkaline water can be found in springs that pass over rocks and pick up minerals, but most commercial alkaline water is processed. Supporters claim alkaline water can help neutralize acid in the body, but experts suggest the body's pH is tightly regulated regardless of diet. For those who wish to try it, homemade versions offer a cost-effective alternative to bottled or filtered options.
DIY Methods to Make Alkaline Water at Home
Method 1: The Baking Soda Solution
Baking soda, or sodium bicarbonate, is a naturally alkaline substance with a pH of about 9. It is one of the quickest and most direct ways to increase your water's pH.
Instructions:
- Start with 8 ounces (1 cup) of purified or filtered water.
- Add 1/8 teaspoon of food-grade baking soda.
- Stir the mixture thoroughly until the baking soda is completely dissolved.
- Drink immediately. You can test the pH with a test strip before consuming to ensure it's in the desired range (usually 8-9.5).
Note: Be mindful of sodium intake, as baking soda adds a significant amount of sodium. People with high blood pressure should consult a doctor before using this method regularly.
Method 2: The Lemon Infusion Method
This method is a bit counterintuitive, as lemons are acidic with a low pH. However, when metabolized by the body, they have an alkalizing effect.
Instructions:
- Fill a pitcher with 1 liter of filtered water.
- Slice half an organic lemon and add the slices to the water.
- For additional minerals, add a pinch of Himalayan pink salt.
- Cover the pitcher and let it sit at room temperature for 8 to 12 hours, or overnight.
- Drink the water in the morning. Slicing the lemon rather than squeezing it allows for a more gradual infusion without making the water overtly acidic.
Method 3: Alkaline pH Drops
For a more controlled and portable option, commercial pH drops can be purchased. They are concentrated solutions of alkaline minerals, such as potassium and magnesium.
Instructions:
- Follow the manufacturer's instructions, typically adding a few drops to a glass of water.
- Stir to combine.
- Start with a small amount and adjust as needed, testing the pH to achieve the desired level.
Warning: Handle these drops with care, as they are highly concentrated and can be irritating if spilled on skin.
Method 4: Mineral Infusion with a Copper Pot
This ancient Ayurvedic technique involves storing water in a copper vessel to allow the copper to naturally ionize the water.
Instructions:
- Fill a clean clay pot with water.
- Place a clean copper glass or container inside the clay pot.
- Leave it to sit for at least 12 hours.
- Optionally, add fruits and herbs like cucumber slices, mint leaves, or basil for flavor and additional mineralization.
Comparison of DIY Alkaline Water Methods
| Method | Cost | Ease | Time | Sodium Added | Notes |
|---|---|---|---|---|---|
| Baking Soda | Very low | Very easy | Instant | Yes | Fastest method, but adds sodium; test with a pH strip. |
| Lemon Infusion | Low | Easy | 8-12 hours | No (unless salt is added) | Pleasant taste, metabolic alkalizing effect; minimal direct pH change in water. |
| pH Drops | High | Very easy | Instant | Low/None | Consistent results, portable, but can be expensive. |
| Mineral Pot | Low | Medium | 12+ hours | No | Infuses water with minerals over time; results can vary. |
Testing the pH of Your Homemade Water
To ensure your homemade alkaline water is within a safe and effective range, it is important to test its pH. There are several accessible methods:
- pH Test Strips: Inexpensive and widely available, these strips change color when dipped in water. Compare the color to the included chart for an approximate reading.
- Digital pH Meter: For more precise and reliable results, a digital pH meter is recommended. These are available online and offer an exact numerical reading.
- DIY Red Cabbage Indicator: For a fun and educational home experiment, you can create a pH indicator using red cabbage juice. It will turn bluish-green in alkaline water.
Risks and Considerations for Consumption
While generally considered safe, consuming large amounts of homemade alkaline water can have potential risks:
- Digestive Disruption: Excessive alkalinity may interfere with your stomach's natural acidic environment, which is crucial for digestion and killing bacteria.
- Mineral Imbalance: Adding alkaline substances can affect the balance of minerals, potentially hindering the absorption of others like iron or zinc.
- Alkalosis: In rare cases, overconsumption could lead to metabolic alkalosis, causing symptoms like nausea, muscle twitching, or confusion.
- Medication Interference: For individuals on medication, especially those affecting stomach acid, alkaline water could interfere with proper absorption. Always consult a healthcare provider.
It is always wise to consult with a medical professional before making significant changes to your hydration habits, especially if you have underlying health conditions like kidney disease.
Conclusion
Making your own alkaline water at home is a simple and affordable way to explore this popular health trend. Whether you choose the quick baking soda method, the naturally flavored lemon infusion, or the controlled pH drops, remember to start slowly and monitor your body's response. Testing your water with pH strips or a digital meter is an important step to ensure the alkalinity is within a safe range. For most people, consuming homemade alkaline water in moderation is safe. However, always prioritize your well-being, listen to your body, and consult a doctor if you have concerns or existing health issues.
