Reboiling Water - Harmful Effects
Boiling water is one of the best methods of removing impurities present and making it fit for consumption.
But have you ever thought about the leftover boiled water? What do you do with it? Do you just throw it away or can you re-boil it and use it for making tea or soups?
Why to avoid using re-boiled water. As with all liquids when you keep boiling it the liquid gets more concentrated. Therefore re-boiling the same amount of water can make it more concentrated or increase the amount of dissolved salts in it.
The harmful effects of re-boiling water are listed below:
Due to the above listed harmful effects of re-boiled water, it is recommended that re-boiled water should not be used to make formula for babies. Studies have also shown that using re-boiled water to make a cup of tea can affect its taste. This is because the amount of oxygen dissolved in the water reduces when you boil it. Filling your vessel or kettle with just the right amount of water as required will not only be beneficial for your health in the long run but would help in preventing and conserving this precious resource.

The harmful effects of re-boiling water are listed below:
- Nitrates: Nitrate salts dissolved in water are usually not harmful but over boiling or re-boiling the same amount of water can cause the nitrates to become a toxin, nitrosamine which is known to cause diseases such as cancer, leukaemia and non-Hodgkin -.
- Arsenic: Re-boiling water can increase the amount of dissolved arsenic in the water. Arsenic in small amounts in water is not harmful and in increased amounts can cause conditions such as cancer, infertility, heart attacks and mental disorder. Prolonged consumption of water with the high amount of arsenic can cause damage to the circulatory system and skin damage.
- Fluoride: The consumption of increased amounts of fluoride dissolved in water can increase your risk of bone disorders such as fractures, tenderness, and pain. In children below 8 years of age excess fluoride can cause damage to teeth and tooth enamel.
- Calcium: Calcium is good for our teeth and bones but re-boiling water increases the dissolved amount of calcium which can cause kidney stones and gall stones.
- Change in water chemistry: Boiling water will get rid or reduce the amount of dissolved gases and volatile compounds in it. This would not only affect the taste but could also increase the concentration of unwanted chemicals and impurities in the water.
