What Is the Optimum pH for Drinking Water?
Human beings cannot live without water, and the quality of drinking water directly affects our health. In recent years, people have paid more and more attention to the pH value of drinking water. Many media have claimed that drinking highly alkaline water is good for health. At present, there is a lack of scientific research to support it, and many people question this statement. Next, let's take a look at whether the pH value of water will affect health.
What is pH?
The pH value is a numerical value used to describe the acidity and alkalinity of a substance, represented by 0~14, 0 is a strong acid, 14 is a strong base, and when the pH value is 7, the substance is neutral.
What is the pH of the water?
Pure water has a pH of 7, which means the water is neutral. But usually the water in nature is not neutral, because the water in nature is usually mixed with other substances, and it is these substances that change the pH value of the water. Usually, the pH value of rainwater is 5.6, showing Acidity, this is because carbon dioxide (CO2) in the atmosphere reacts with water (H2O) to form carbonic acid (H2CO3), and carbonic acid is weakly acidic, which causes rainwater to be weakly acidic. Here, when the rainwater If the pH value is less than 5.6, it is what we usually call acid rain.
So, why is the water on the surface usually slightly alkaline? This is because when the rain falls to the surface, it reacts chemically with various minerals in the surface rock formation, and the carbonic acid (H2CO3) in it reacts with various metal minerals to form bicarbonate, which is weakly alkaline. Therefore, Surface water is usually slightly alkaline and has a high mineral content.
What are the health benefits of alkaline water?
1. Promote metabolism
The acidity and alkalinity of weakly alkaline water is very close to the body fluids of healthy people, so the alkaline ions in it can be directly and quickly absorbed by the human body, neutralize the acidic substances produced in the body, and at the same time promote the metabolism of the human body and help the transportation of nutrients in the body. Digestion, absorption, excretion of metabolic waste, effectively avoiding the generation of acidic body and improving immunity.
2. Regulate gastric acid secretion
Weak alkaline water can help neutralize gastric acid, so if there is too much gastric acid secretion, drinking some weak alkaline water can help regulate the body, but it is not suitable for long-term consumption, and it will also stimulate gastric acid secretion.
3. Improve cardiovascular disease
Drinking some weak alkaline water in moderation can also improve cardiovascular and cerebrovascular diseases, soften blood vessels, dissolve excess cholesterol on blood vessel walls, and lower blood pressure and lipids.
How to check the pH of water?
1. Put a piece of pH test paper into the water to be tested and keep it for 1 second.
2. Immediately after the test paper changes color, compare it with the pH control table.
3. The value corresponding to the color closest to it is the pH value of the water.
How to get weak alkaline water?
Generally, water with a pH value greater than 8 can be called alkaline water, but the pH value of the weak alkaline water declared on the market is usually between 7 and 8, so how can we correctly choose weak alkaline water? Well, an easy way is to check the label on the bottle of drinking water. Usually, weakly alkaline water will have its pH value marked on the bottle, so we can easily get the information about the bottled water you want to buy by checking the label.
