Insufficient Hydration Leads to Poorer Sleep Quality in Young Adults

Dehydration from insufficient fluid intake, particularly less than 1500 mL daily, is associated with poorer sleep quality, more sleep disturbances, and reduced sleep efficiency in college students.

  • Daily intake below 1500 mL correlates with elevated PSQI scores indicating poor sleep.
  • Dehydrated college students report more frequent interruptions during nightly rest.
