Importance of pH in our lives
Understanding pH: An Essential Water Measurement
You might not hear your local news broadcaster mention the daily pH levels of Kuala Lumpur, but pH is a crucial measurement in assessing water quality. Perhaps you remember testing pH in a school science project; it’s an often-overlooked aspect of our environment. The pH of water bodies is significant not only for the organisms that inhabit them but also as an indicator of environmental changes, such as pollution levels.
What is pH?
pH, which stands for "potential Hydrogen," measures how acidic or alkaline water is, ranging from 0 to 14. A pH of 7 is considered neutral, values below 7 indicate acidity, and values above 7 indicate alkalinity.
The pH scale operates on a logarithmic basis, meaning each whole number change represents a tenfold difference in acidity. For instance, water with a pH of 5 is ten times more acidic than water with a pH of 6.
pH in Our Bodies
The importance of pH extends beyond environmental factors; it plays a vital role in our bodily functions as well. Different organs have varying pH levels, crucial for their respective processes. Here’s a brief overview:
Gastric Acid: 1.5 - 3.5 (highly acidic for digestion)
Human Skin: 5.5 (slightly acidic, protecting against pathogens)
Blood: 7.34 – 7.45 (essential for transporting oxygen)
Cerebrospinal Fluid: 7.5 (protects the brain and spinal cord)
A deviation from the normal blood pH can lead to symptoms like dizziness or fatigue. Drinking water can be an effective and convenient way to help maintain appropriate pH levels in your body.
pH in Drinking Water
Different types of water have varying pH levels, which can be influenced by the filtration method. Here are some examples:
Reverse Osmosis (R.O.) Water: 6.6 - 6.8 (will drop to 5.5 in time)
Distilled Water: 7.0
Bottled Mineral Water: 7.3 - 7.6
Ionized Water (Alkaline): 7.5 - 10.5
Ionized Water (Acidic): 3.5 - 6.5
It’s vital to ensure your water filters are replaced regularly. Expired filters can harbor bacteria and substances that lower the pH of your drinking water, negatively impacting your health.
Conclusion
Understanding and monitoring pH is crucial for both environmental health and personal well-being. By being mindful of the pH levels in the water you consume, you can contribute to your health and ensure the quality of your drinking water.
