Is Distilled Water Safe to Drink? Facts & Benefits

  • Surya 

Is distilled water safe to drink? Have you ever wondered about this? It’s a common question for many people. I was also one of them. To answer the question, yes, it is safe. Just that you don’t get minerals that you can get from tap or purified water.

Let’s explore the pros and cons of drinking distilled water, addressing misconceptions along the way. We’ll also discuss how it may impact your overall diet and health.

Is Distilled Water Safe to Drink?

Distilled Water: Generally Safe for Consumption

Distilled water is generally considered safe for consumption. It goes through a process called distillation, where impurities and contaminants are removed by boiling the water and then collecting the steam, which is later condensed back into liquid form. This process effectively removes most minerals, bacteria, viruses, and other substances from the water.

What Is The Catch In Drinking Distilled Water?

One concern often raised about distilled water is that it lacks essential minerals that are found in other types of drinking water.

However, the absence of minerals does not pose any significant health risks for most people. While minerals like calcium and magnesium are important for overall health, they can easily be obtained from a balanced diet that includes fruits, vegetables, dairy products, and other sources.

Benefits for Certain Individuals

Drinking distilled water can actually be beneficial for certain individuals with specific medical conditions or circumstances:

  1. Kidney Stones: People who have a history of kidney stones may benefit from drinking distilled water. Since it has no mineral content, it reduces the risk of stone formation.
  2. Heavy Metal Detoxification: Distilled water can also aid in heavy metal detoxification as it does not contain heavy metals commonly found in tap water.
  3. Medical Procedures: Distilled water is often used during medical procedures where sterility is crucial because its purity helps prevent infections.
  4. Formula Preparation: Parents preparing infant formula may choose to use distilled water to minimize exposure to contaminants that could potentially harm their baby’s delicate immune system.

Considerations When Drinking Distilled Water

While distilled water is generally safe to drink, there are a few considerations to keep in mind:

  • Electrolytes: Since distilled water lacks minerals like sodium and potassium electrolytes, it should not be relied upon as the sole source of hydration during intense physical activity or prolonged periods of sweating. In such cases, sports drinks or electrolyte-rich beverages can help replenish these essential nutrients.
  • Mineral Intake: If you primarily consume distilled water, it’s important to ensure that you are obtaining the necessary minerals from other sources in your diet.
  • Variety: Drinking only distilled water for an extended period may lead to a monotonous taste experience. It might be enjoyable to switch things up occasionally by consuming other types of drinking water like bottled water or tap water.

Risks of Drinking Distilled Water

Long-Term Consumption and Mineral Deficiencies

Long-term consumption of only distilled water can potentially lead to mineral deficiencies in the body. Unlike tap water or natural spring water, which contains essential minerals like calcium, magnesium, and potassium, distilled water is stripped of these minerals during the distillation process.

Without an adequate intake of minerals through other sources such as food or supplements, relying solely on distilled water for hydration may result in a deficiency over time. These minerals play crucial roles in maintaining healthy bones, supporting nerve function, regulating muscle contractions, and promoting overall well-being.

Electrolyte Imbalances from Excessive Consumption

Electrolytes are essential for maintaining proper fluid balance in our bodies. They help regulate nerve function, and muscle contractions and keep us hydrated. However, excessive consumption of distilled water can disrupt this delicate balance by diluting electrolyte levels.

While it’s important to stay hydrated, drinking excessive amounts of any type of water can lead to electrolyte imbalances. This is especially true with distilled water since it lacks the natural minerals that help maintain electrolyte levels within a healthy range.

To avoid electrolyte imbalances when consuming distilled water, it’s crucial to ensure a balanced diet that includes foods rich in electrolytes or consider adding electrolyte-enhancing supplements to your routine.

Caution for Infants and Athletes


Infants have unique hydration needs due to their small size and developing bodies. While distilled water may be suitable for mixing formula or baby food preparation due to its purity, using solely distilled water for infants’ daily hydration needs may not be ideal.

Similarly, athletes who engage in intense physical activities require more than just plain distilled water for optimal hydration. During exercise or prolonged periods of sweating, the body loses not only fluids but also vital electrolytes like sodium and potassium. It’s really important to make sure your muscles work properly and you don’t get dehydrated by keeping your electrolytes topped up.

Comparing Distilled Water and Filtered Water

distilled vs purified water

Distilled water and filtered water are two popular options for drinking water. While they both undergo different purification processes, each has its own advantages and considerations. Let’s take a closer look at the differences between distilled water and filtered water to help you make an informed decision about which one is right for you.

Distilled Water Purification Process

Distilled water is produced through a process called distillation. During distillation, impure water is heated to create steam, which is then condensed back into liquid form. This process effectively removes impurities such as chemicals, minerals, bacteria, and other contaminants from the original water source.

Filtered Water Retains Essential Minerals

On the other hand, filtered water goes through a filtration process that uses various types of filters to remove impurities. Unlike distillation, filtering does not involve heating or evaporating the water. Instead, it passes through different layers of filters that can include activated charcoal or carbon filters.

One key difference between distilled and filtered water is that while distillation removes almost all minerals from the water, filtering retains essential minerals like calcium and magnesium that are beneficial for our bodies.

Advantages of Distilled Water

Distilled water offers several advantages depending on personal preferences and needs:

  • Purity: The distillation process effectively eliminates most contaminants from the original source.
  • Safety: Distilled water can be a good option if your primary concern is removing potentially harmful substances from your drinking water.
  • Versatility: Distilled water can also be used in various household appliances such as humidifiers or irons since it lacks mineral buildup that could affect their performance.

Advantages of Filtered Water

Filtered water also has its own set of advantages:

  • Retained Minerals: Unlike distilled water, filtered options retain essential minerals that are beneficial for our overall health.
  • Improved Taste: Filtering helps improve the taste and odor of water by removing chlorine and other unwanted substances.
  • Convenience: Many filtration systems are available, including faucet-mounted filters or pitcher filters, making it easy to access clean and filtered water at home.

Is Purified Water The Same As Distilled Water?

In conclusion, while both purified and distilled water undergo processes to remove impurities, they are not the same. Purified water refers to any water that has been treated to remove contaminants, which can include various methods such as filtration, reverse osmosis, or distillation. On the other hand, distilled water specifically goes through a process of boiling and condensation to separate impurities from the water molecules.

It ultimately depends on your specific needs and preferences. If you are concerned about potential contaminants in your tap water and want a reliable option for safe consumption, both purified and distilled water can be suitable choices. However, if you prefer a more thorough purification process that removes even volatile compounds like certain chemicals or minerals, then distilled water might be the better option for you.


Can I use distilled water for cooking?

Absolutely! Distilled water is safe to use in cooking. It can be used for making tea or coffee, preparing soups or sauces, boiling vegetables, and baking. Its purity ensures that no unwanted flavors or impurities will affect the taste of your food.

Is it necessary to drink only distilled water?

No, it is not necessary to drink only distilled water. While some people choose to consume only distilled water due to its purity, others prefer the taste of mineral-rich spring waters or opt for filtered tap water. It ultimately depends on personal preference and individual circumstances.

Can I give my pets distilled water?

Yes! Just like humans, pets can also benefit from drinking clean and safe water. Distilled water can be an excellent choice for providing them with hydration but you should not restrict your pets to just distilled water. Because, just like you, your pet would also need minerals present in water, and restricting them to drink distilled for the long term is not at all ideal.

Can I use distilled water in my humidifier?

Yes! Using distilled water in your humidifier is recommended as it helps prevent the buildup of mineral deposits in the device. This ensures that you are releasing clean and pure moisture into the air, which can be especially beneficial for individuals with respiratory issues.

Is distilled water good for plants?

While distilled water is safe for plants, it may not always be the best choice. Since distilled water lacks minerals that are naturally present in many water sources, using it exclusively for watering your plants may lead to nutrient deficiencies over time. It’s generally recommended to provide a balance by alternating between distilled and tap water or using a fertilizer to ensure your plants receive adequate nutrients.
