Is it safe to regularly drink distilled water?
Hello, doctor.
I would like to ask if drinking more than 1500cc of distilled water made from tap water every day at the workplace has any adverse effects on the human body, especially the kidneys? Is it safe to consume this type of water regularly? If not, are there any methods to minimize the negative effects of drinking this water? Thank you!

1.
Water contains trace elements necessary for the human body, such as magnesium, calcium, and phosphorus found in minerals.
Distilled water, while effective in eliminating bacteria, raises concerns about the potential reduction of trace elements in the water.
2.
To reduce bacteria in water while preserving trace elements, I believe a better method is to bring the water to a boil and then continue boiling for an additional 3-5 minutes.

More Info
Drinking distilled water daily is generally considered safe for most individuals, including those with healthy kidney function. Distilled water is created through the process of distillation, which involves boiling water to produce steam and then condensing that steam back into liquid form. This process removes impurities, minerals, and contaminants, resulting in very pure water. However, there are some considerations to keep in mind, especially regarding kidney health and overall hydration.
Kidney Function and Water Intake
The kidneys play a crucial role in regulating the body's fluid balance and electrolyte levels. They filter waste products from the blood, regulate blood pressure, and maintain the balance of electrolytes such as sodium, potassium, and calcium. When it comes to hydration, the kidneys are adept at adjusting urine concentration based on the amount of water consumed. If you drink a lot of water, your kidneys will produce more dilute urine to excrete the excess fluid.
For most healthy adults, a daily water intake of around 2 to 4 liters is considered normal, depending on factors such as activity level, climate, and individual health conditions. Drinking distilled water in moderation—such as 1500cc (1.5 liters) per day—should not pose any significant risks to kidney health for most individuals. However, there are a few points to consider:
Potential Concerns with Distilled Water
1. Lack of Minerals: One of the primary concerns with drinking distilled water regularly is that it lacks essential minerals that are typically found in natural water sources, such as calcium and magnesium. While the body can obtain these minerals from food, relying solely on distilled water may lead to a deficiency over time, especially if dietary intake is inadequate.
2. Electrolyte Balance: Drinking large amounts of distilled water could potentially dilute the electrolytes in your body, particularly if you are not consuming enough minerals through your diet. This is particularly important for individuals with certain health conditions, such as kidney disease, where electrolyte balance is critical.
3. Taste and Preference: Some people find distilled water to have a flat taste compared to mineral or spring water. This may affect your overall hydration if you find it less palatable.
Recommendations for Safe Consumption
If you choose to drink distilled water daily, here are some recommendations to minimize any potential negative effects:
- Balanced Diet: Ensure that your diet is rich in essential minerals and electrolytes. Foods such as leafy greens, nuts, seeds, dairy products, and whole grains can help provide the necessary nutrients that may be lacking in distilled water.
- Monitor Hydration: Pay attention to your body's hydration signals. If you notice symptoms of dehydration, such as dry mouth, fatigue, or dark urine, consider adjusting your water intake or incorporating other types of water that contain minerals.
- Consult a Healthcare Professional: If you have pre-existing health conditions, particularly related to kidney function, it’s advisable to consult a healthcare professional or a registered dietitian. They can provide personalized recommendations based on your health status and dietary needs.
Conclusion
In summary, drinking distilled water daily in moderation is generally safe for healthy individuals, including those with normal kidney function. However, it is essential to maintain a balanced diet to ensure adequate mineral intake and to be mindful of your body's hydration needs. If you have specific health concerns or conditions, consulting with a healthcare provider is always a prudent approach.
