Is it safe to drink distilled water?

An essential element of staying in good health is keeping your body hydrated with safe drinking water. But is it safe to drink distilled water instead of any other water options?

Together we will go through the features of distilled water as we decide on whether it is safe for drinking.  

What Is Distilled Water?

Distilled water is one of the four different types of water that is available for drinking. Its alternatives include spring water, plain tap water, and well water. 

All these alternatives have their risks, particularly from impurities that can be found in them. Minerals, contaminants, and nutrients are a few of these impurities that exist in almost all water. 

Distilled water is the product of a boiling and evaporation process that rids the water of these impurities. As a result, water that has been distilled lacks metals, inorganic compounds, and minerals. The absence of these substances in water gives distilled a distinct, flat taste that is not loved by all. 

Distilled water shares similarities with other purified water types. The only distinction is in the way the purification process is implemented. This ancient water purification method is relatively complex and hard to achieve without the aid of a water distillation machine. 

Is distilled water safe to drink? 

Absolutely. Distilled water compliments a balanced diet. Healthy adults who eat a balanced diet can drink distilled water. It helps cleanse the body, reduce the risk of disease, and minimize exposure to harmful chemicals. 

However, it is crucial that before adopting distilled water as your preferred choice, you eat a varied diet that provides you with needed nutrients. This is because distilled water does not contain minerals found in other drinking water sources. 

Magnesium and calcium are essential nutrients the body needs. These nutrients are flushed from water during the distillation process. It is therefore important to have alternative sources of these nutrients when drinking distilled water. 

The World Health Organisation (WHO) outlines three adverse effects of drinking distilled water which are:

  • A flat taste that is largely unappealing, leading to a reduction in the consumption of the required water intake.
  • Increased urine output with the possibility of electrolyte imbalance as a result. 
  • A reduction in the body’s metabolic function.  

The demineralization of water through distillation can alter the delicate balance of sodium, phosphorus, zinc, magnesium, calcium, and fluid in the body. Therefore, minerals discharged through sweat or urine will not be replaced if a person drinks distilled water.

However, as most developed world population eat a rich, varied diet of beverages and foods, there is no danger of drinking distilled water. 

Distilled water vs. the purified water 

Although all distilled water is purified water, not all purified water is distilled water. Distilled water is a purified water type that has undergone a process to remove all minerals and contaminants. 

On the other hand, purified water is without contaminants and chemicals but may still contain some minerals. There are three ways in which water can be purified:

  • Deionization: This process gets rid of the mineral ions and salts in water. 
  • Reverse osmosis: This method involves water filtration through a unique material known as a semipermeable membrane. Salt and contaminants are removed from the fluid when it passes through this material.
  • Distillation: This process involves boiling water and condensing the steam back into liquid to rid the water of all impurities and minerals.

Common uses for distilled water 

Distilled water has many uses and benefits. A person who consumes distilled water is drinking water without additives. It also helps the body get rid of waterborne pathogens. Disease-causing bacteria cannot survive distillation. Tap water contains low levels of harmful chemicals allowed by the Environmental Protection Agency (EPA). Distilled water gets rid of all these elements. 

Distilled water is commonly used in automobiles and household appliances because it is devoid of chemicals. Popular uses for distilled water include:

  1. Inverter batteries
  2. Steam irons
  3. Car cooling systems
  4. Laboratory equipment and experiments
  5. Watering plants
  6. Aquariums (In such circumstances, mineral supplements should be added to fish food)
  7. Medical devices such as the Continuous Positive Airway Pressure (CPAP) device that helps combat sleep apnea. 


Distilled water is unlikely to improve your health dramatically. It will not hurt you either, provided you consume a balanced diet that provides you with alternative sources of the minerals you need. 

Besides drinking water, a water distiller is needed in every home for other purposes. A guide to the best water distiller will ensure you make the best buying decision.
