First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed study looked at 1,740 newly married couples to see if the bacteria in their mouth, eyes, and gut are linked to sleep problems, vision issues, and mood. Participants provided samples and completed surveys about sleep, anxiety, depression, and dry eye symptoms. The goal is to understand how these bacteria might influence health, but it does not test any treatment.
