Water as Tampon Lubricant: Risks and Safe Alternatives

Do not use plain water as a tampon lubricant.

• pH disruption: Vaginal pH (3.8–4.5) is acidic; water (pH 7) dilutes protective lactobacilli, increasing infection risk (BV, yeast).
• Reduced absorbency: Water pre-wets tampon fibers, decreasing menstrual fluid capacity → leakage.
• No lubricity: Water evaporates; does not reduce insertion friction.

Safe alternatives: FDA-cleared, water-based personal lubricants (e.g., Astroglide, K-Y Jelly, Good Clean Love) labeled for vaginal use. Avoid oils, petroleum jelly, saliva, or homemade solutions.
