What is alkaline water?
‘Alkaline’ refers to pH level, a number that ranges from 0 to 14. Something with a pH less than 7 is acidic and that with greater than 7 is alkaline. The pH of regular drinking water is around 7. Chemicals and gases can mix and react with water to change its ph level to make it acidic or alkaline.
Because of higher pH level of Alkaline water, it can neutralize acids in the body.
However, pH alone doesn’t give the water all the alkaline properties. Alkaline water must also contain negative oxidation reduction potential (ORP).
What Is the ORP Level of Water?
ORP stands for Oxidation Reduction Potential and is a popular water quality parameter. It is measured in “mV” (millivolts) using an ORP meter, and the value can be either positive or negative. Water with a negative ORP is considered a good antioxidant and is more hydrating. Antioxidants counteract free radicals that create aging and disease in the body.
To understand antioxidant and ORP better, basic understanding of what ion/electron exchange is needed.
In the world around us there is a continuous exchange of electrons between substance everywhere, even in our bodies, to reach a state of stability.
- oxidizing agents are substances that lack electrons and seek them
- anti-oxidizing (reducing) agents are substances that have surplus electrons and can donate them
Oxidation-reduction potential (ORP) is a measurement of this capability of oxidizing (take electrons) or reducing (give electrons) another substance.
- positive ORP value is an indicator of an oxidizing agent. The higher the reading, the more oxidizing it is.
- negative ORP value is an indicator of a reducing agent. The lower the reading, the more anti-oxidizing it is.
Most types of water, including tap and bottled water, have positive ORP value and hence are oxidizing agents.
Alkaline ionized water has negative ORP value and hence is an anti-oxidizing agent. It donates extra electrons to free radicals (these seek electrons) and neutralize their harmful effects in the body.
Make Your Water Healthier
You can gain the benefits of anti-oxidizing water at home by putting your tap water through a water filter that makes the water alkaline ionized. In addition to changing the pH level of your tap water, these machines change the ORP to offer the benefits of antioxidants.
