What is the Best pH Water to Drink? Understanding Water pH
This article examines the question, "what is the best pH water to drink," by delving into the meaning of pH, its measurement, and its impacts on our health and taste.
What does the pH of Water Mean?
pH is a measure of how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is considered neutral, which is the pH of pure water at 25°C.
Any pH below 7 is acidic, and any pH above 7 is basic or alkaline. The lower the pH, the higher the acidity; conversely, the higher the pH, the higher the alkalinity.
When it comes to water, the pH can be influenced by several factors, including the presence of dissolved minerals and gases.
For instance, rainwater's pH can be affected by carbon dioxide in the atmosphere, and groundwater can become more alkaline due to minerals such as calcium and magnesium.

How to Check the pH of Water?
Checking the pH of water is a straightforward process. You can use pH test strips, digital pH meters, or pH indicator solutions.
The test strips change color when dipped into the water, and the color can be compared to a reference chart to determine the pH.
Digital pH meters are more accurate and provide a direct digital reading of the pH.
pH indicator solutions work similarly to test strips but are typically used in a lab setting.
What is the Standard pH for Drinking Water According to the FDA and WHO?
The U.S. Food and Drug Administration (FDA) does not specifically regulate the pH levels of bottled water. However, it does consider low pH levels (highly acidic) as potentially corrosive and a risk to public health.
On the other hand, the World Health Organization (WHO) suggests that the pH of drinking water should ideally be between 6.5 and 8.5.
This recommendation is based on taste preferences, corrosion prevention, and potential health impacts.

Is High pH Water Better for You?
High pH or alkaline water has gained popularity due to its purported health benefits, including balancing the body's pH level, improving hydration, and neutralizing acid in the bloodstream.
However, the scientific evidence supporting these claims is not robust.
The human body is well-equipped to maintain its pH balance regardless of diet, and while alkaline water is generally safe to drink, it's unlikely to significantly affect blood pH.
Moreover, excessively high pH levels (over 11) can lead to skin irritation and eye problems.
Does Drinking Water pH Make a Difference?
Drinking water pH can make a difference in terms of taste and potential health impacts.
Water with a low pH (acidic) can taste sour, while high pH (alkaline) water can taste bitter or soda-like.
Extremely low or high pH water can also be corrosive, potentially leaching metals from pipes into the water.
In terms of health, it's still under debate whether the pH of drinking water can have significant impacts.
Some research suggests that alkaline water might help with certain health conditions, such as acid reflux, but more comprehensive studies are needed.

Is Alkaline Water Good for the Kidneys?
Alkaline water may be beneficial for kidney health by neutralizing excess acid in the blood, which could potentially reduce kidney stress.
Some research has also suggested that alkaline water might help patients with chronic kidney disease by slowing the progression of the disease.
However, these claims require more extensive scientific research to be validated.
What does Acidic Water do to your Body?
In general, mildly acidic water (pH slightly less than 7) isn't harmful to your health. However, drinking water that is highly acidic (significantly lower than pH 7) can potentially cause problems over time.
The acid in the water might irritate the digestive system, leading to symptoms like heartburn or upset stomach.
Furthermore, acid can leach metals from the plumbing system into the water, leading to elevated levels of metals like copper or lead, which can have various health effects when ingested over time.
There's also some research suggesting that a lower pH in drinking water might be linked to an increased risk of heart disease, but these findings are still preliminary and more research is needed.
In conclusion, while the pH of water can have some influence on taste and possibly health, it's just one of many factors to consider in assessing water quality.
The presence of contaminants like bacteria, heavy metals, or harmful chemicals is a much more significant health concern than pH alone. Therefore, it's always a good idea to ensure your water source is safe and meets the recommended guidelines, regardless of its pH level.
As for the alkaline water trend, it's generally safe to drink but unlikely to bring substantial health benefits.
The human body is remarkably efficient at maintaining its own pH balance, regardless of what we consume.
If you enjoy the taste of alkaline water or find it helps with issues like acid reflux, it's fine to drink, but it's not a necessity for most people.
The most important thing is to stay hydrated, so find a source of water that you enjoy and drink up. Your body will thank you.
