Whether a high pH is "good" depends on the context.
For drinking water:
- A pH between 7 and 8.5 is generally considered safe for drinking.
- While high pH in drinking water (above 8.5) isn't inherently harmful, it can lead to a bitter taste and may potentially affect the absorption of certain minerals.
- There is no evidence to support the claims of improved health benefits from drinking alkaline water.
For skin:
- The skin's natural pH is slightly acidic.
- High pH water can disrupt this natural balance, leading to dryness, itchiness, and irritation.
For vaginal health:
- A high vaginal pH can create an environment favorable for bacterial and yeast infections.
For soil:
- A high soil pH can limit the availability of essential nutrients for plants, such as iron, boron, zinc, and copper.
For food preservation:
- A very high pH can prevent microbial growth, which is beneficial in food preservation processes.
Overall, whether a high pH is "good" depends on the specific application and the desired outcome.
