Based on expert information, the premise that saliva is a good lubricant for general use is not supported. In fact, experts indicate it lacks the necessary qualities and can even be counterproductive.
Expert Opinion on Saliva as a Lubricant
According to Dr. Gersh, saliva "has no innate qualities that would make it a good lubricant." This expert assessment directly challenges the idea that saliva is effective for lubrication purposes, highlighting specific characteristics that make it unsuitable.
Why Saliva is Not an Ideal Lubricant
Dr. Gersh identifies several reasons why saliva falls short when compared to effective lubricants:
- Lack of Slippery Consistency: Saliva does not possess the consistently slippery texture required to significantly reduce friction over time.
- Rapid Evaporation and Drying: Primarily water-based, saliva evaporates quickly when exposed to air or friction, leading to dryness rather than sustained lubrication.
- Potential for Irritation: For some individuals or types of skin/tissue, saliva can cause irritation, which is undesirable in a lubricant.
These points underscore why, despite being a natural bodily fluid, saliva does not function effectively as a lubricant when compared to substances specifically designed for this purpose.
