RO water of low TDS is harmful for Health

A few days ago i was watching a video claiming that RO water, which is now common in most households, is decreasing the immunity. Immunity power is that power that makes us capable to resist from different types of virus and bacteria and keep our body healthy. That video claimed that the purity of RO water makes our body loose its resistance power and we become prone to more diseases. In this article we will try to figure out if there is some truth in such claims or not.

When we researched on internet and the official website of WHO (World Health Organisation), we came to know that the claims about low TDS and its effect in decreasing immunity were correct. If you want to know how then read further.

How do water of low TDS impact negatively ?

• It is a tendency of water to extract the minerals from nearby substances to increase its TDS and become less reactive. When a RO decreases the TDS value of water, it become highly reactive. If that water is stored in plastic container of a bottle then it can become severely harmful. Even if it is not stored and just used for drinking purpose, then it will try to add minerals into it from the mineral reserves in our body and drain them out through urine. 
• TDS is Total Dissolved Solids. TDS measures the amount of solids, both organic and inorganic, dissolved in the water. It also contains soe essential minerals for human body. When a RO purifier reduces the TDS value of water, several essential minerals are also lost along with the micro-organisms that are harmful for us. Water with low mineral content is harmful for our body. 
• According to a research published on WHO website when some rats are given water of TDS less than 75mg/L then it increased the water intake, diuresis, extracellular fluid volume and serum concentration of sodium and chloride ions and their increased elimination from body. Overall it is a very negative effect on rats. The reduced amount of minerals in water can't be compensated by balanced diet which is adequate in caloric value, nutrients and salt.
• A similar experiment was done on human volunteers as they were given water of TDS value less than 100mg/L. They reported the same results as rats and increased the elimination of sodium, potassium, chloride, calcium and magnesium ions from the body. It confirmed that water of low TDS is severely harmful for human body.
• Some symptoms that are often seen in people consuming low TDS water for short duration are tiredness, weakness and headache. If it is done for prolonged duration then more severe symptoms are muscular cramps and impaired heart rate. Low TDS water leaches the essential minerals from body and function of some of the vital organs of human body is affected.
• Those who are familiar with Water Poisoning, know that if very high amount of water is consumed in a short time then it can be poisonous sometimes. Chances of water poisoning is quite high with RO water due to it low TDS value.
• Minerals such as sodium and potassium are very important for nervous system to work properly and their deficiency can result in problems in brain functioning.
• Deficiency of these minerals not only make us sick but also unable to fight diseases due to weaker immune system.
• Lack of minerals can also create hormonal imbalance in body.
