Association between sleep duration and thirst in a nationally representative cross-sectional survey.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We aimed to examine the association between sleep duration and thirst level, indicator of altered hydration status. We performed a secondary analysis of the 2018 Korean Sleep-Headache Study, a nationally representative cross-sectional survey conducted in the Republic of Korea. Of 2,501 participants who completed the survey, 2,468 were included in the final analysis (age, 47.9 ± 16.4 years; 49.8% male). Participants were categorized into the high- or low-thirst group based on self-reported thirst frequency. Sleep duration was grouped as ≤ 6, > 6-7, > 7-8, and > 8 h. Logistic regression assessed the relationship between sleep duration and high thirst, adjusting for multiple lifestyle and health variables. Short sleep duration (≤ 6 h) was significantly associated with high thirst (adjusted OR 1.69; 95% CI, 1.00-2.86; p = 0.049), compared to the reference group (> 7-8 h). Age-stratified analyses revealed that adults ≥ 50 years showed a significant association between sleep duration of > 6-7 h and high thirst (OR 2.26; 95% CI, 1.23-4.12; p = 0.01). Sensitivity analyses indicated diabetes and habitual snoring as key contributors, and depressive mood consistently predicted high thirst. These findings suggest a complex interplay between sleep, thirst perception, and hydration, potentially mediated by metabolic and sleep-related disorders.
