PMID 40827379WHAT IT FOUND
In adults with hypertension and diabetes, poorer sleep hygiene was associated with higher stress.
Unsafe at night, uncomfortable physical environment, uncomfortable temperature, and eating at bedtime were linked to stress. This is an association, not proof that changing habits lowers stress.
Key findings
01Poorer sleep hygiene was associated with higher psychological stress (Model 3 β = 0.61, 95% CI 0.22–1.01).
02Poor sleep quality was associated with higher stress, but sleep quality did not moderate the association between sleep hygiene and stress.
03Unsafe at night, uncomfortable physical environment, uncomfortable temperature, and eating at bedtime were each positively associated with stress; unsafe at night was the strongest.

What it does not show
This was a one-time survey, so it cannot show that poor sleep hygiene caused higher stress or that fixing it would reduce stress. Participants were adults from a single healthcare system in Maryland, so the results may not apply to other populations. Sleep quality was self-reported, not measured objectively. The sleep hygiene measure was adapted and lacked detailed psychometric validation, and it did not specify a recall period. The measure did not include other sleep hygiene factors such as consistent sleep schedules, limiting alcohol or caffeine, regular exercise, or avoiding late naps. Comorbid conditions, obstructive sleep apnea, or psychological disorders may have affected the results.
Declared interests
The authors declared no conflicts of interest. The work was supported by the National Institute on Minority Health and Health Disparities Mid-Atlantic Center for Cardiometabolic Health Equity Pilot Grant (5P50MD017348).
The easy way to misread this
Do not conclude that improving sleep hygiene reduces stress. This was a cross-sectional survey, not a treatment trial, and the association could be explained by stress influencing habits or by other factors.
