Daily associations between the physical environment and sleep among a diverse, national sample of young adults.
Article in Sleep health, 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
objectivesWe examined daily between- and within-person associations of the physical sleep environment with actigraphic and self-reported sleep.
methodsYoung adults in the Future of Families "Young Adult Sleep Study" (n=372; 60% F) self-reported daily for 2 weeks whether 3 sleep environment factors (i.e., temperature, light, and noise) disrupted the previous night's sleep while wearing wrist-actigraphs. Multilevel models examined between- and within-person associations between environmental factors and actigraphic sleep timing, duration, wake after sleep onset, sleep maintenance efficiency, and self-reported sleep quality.
resultsEnvironmental factors were associated with sleep health in between-person and/or within-person findings. Between-person: A "too hot" environment was associated with greater wake after sleep onset (b = 9.93 minutes, 95% CI [3.64,16.21], P = .006) and lower sleep maintenance efficiency (b = -1.78%, 95% CI [-3.01, -0.54], P = .010). "Too noisy inside" was associated with lower sleep maintenance efficiency (b = -2.97%, 95% CI [-5.24, -0.70], P = .03) and 88% decreased odds of good sleep quality (OR = 0.12, 95% CI [0.02, 0.54], P = .006). A "too bright" environment was associated with 90% decreased odds of good sleep quality (OR = 0.10, 95% CI [0.01, 0.61], P = .010) and later sleep onset (b = 111.05 minutes, 95% CI [26.67, 195.42], P = .010), midpoint (b = 122.95 minutes, 95% CI [41.22, 204.69], P = .010), and offset (b = 131.54 minutes, 95% CI [39.7, 223.40], P = .010). Within-person: A "too hot" environment was associated with lower sleep maintenance efficiency (b = -0.79%, 95% CI [-1.13, -0.45], P<.001) and 45% decreased odds of good sleep quality (OR = 0.55, 95% CI [0.39, 0.79], P = .001) that same night.
conclusionsCharacteristics of the physical sleeping environment (temperature, brightness, and noisiness) were associated with later sleep timing and worse sleep quality but not sleep duration. Future research should examine mechanisms by which environmental factors may affect sleep health.
