RO Water or Reverse osmosis water is a fancy scientific term used by many these days. RO water will be produced through reverse osmosis (RO) process associated with purifying water. But most people don’t know what an RO system is.
Reverse Osmosis or RO is a method of removing contaminants from the source water by applying pressure. The machine lets the water flow through a series of artificial, semi-permeable membranes to further remove impurities. Part of the definition of reverse osmosis water is it is “purified water.” It means all the sediment, heavy metals, hard minerals, nutrients, viruses, and bacteria (both the good and bad) are no longer present. Drinking water should contain minimum levels of certain essential minerals.
Sufficient evidence is now available to confirm the health consequences from drinking water deficient in calcium or magnesium. According to Frantisek Kozisek, National Institute of Public Health, Czech Republic, zero electrolytes and no antioxidants water is equal less hydrating water. Of course, alkaline water is rich in antioxidants and electrolytes. This helps hydrate the body and neutralize harmful free radicals. Potential consequences of drinking demineralized water on vital body functions.
Drinking water with a low mineral content i.e. water with low TDS (Total Dissolved Salts) has a negative effect on our body’s homeostasis. Consuming RO demineralized water causes debilitating symptoms such as headache, tiredness, and weakness, muscular cramps, and impaired heart rate along with a negative impact on hormone secretion, kidney functions, and bone mineral density.
Consuming water that is low in calcium and magnesium is associated with an increased risk of cardiovascular diseases, fractures in children, preterm birth or low birth weight, certain neurodegenerative diseases, etc., when compared to natural water consumption
Waste of water
A 2013 study by researchers at North Dakota State University revealed: “An RO unit delivering 2 gallons of treated water per day may discharge 8 to 15 gallons of waste water per day to the septic system”. – Tom Scherer, Ph.D., and Roxanne Johnson
What we should do
Drinking water should contain minimum levels of certain essential minerals (and other components such as carbonates).
How to re-mineralize RO water:
– Add a mineral-rich salt (Example – Himalayan sea-salt)
– Mineral drops for water
– Alter the RO water pH level with a filter
– Use an alkaline pitcher.
