higher indoor humidity tracks greater insomnia severity in older adults
Exact: r = 0.64
Higher indoor humidity linked to greater insomnia severity in older adults
Among 39 community-dwelling older adults without dementia, continuous sensor measurements of indoor humidity showed a significant positive correlation with insomnia severity (r = 0.64). This indicates that higher humidity in the home environment may disrupt sleep in older adults, suggesting humidity control as a potential target for sleep health interventions.
Additionally, increased evening light exposure correlated with higher stress (r = 0.75), higher CO2 levels were associated with poorer delayed recall (r=-0.64), and higher humidity was linked to increased insomnia severity (r = 0.64).
