In a Sham-Controlled At-Home Study, Sleeping on a Temperature-Controlled Mattress Topper Improved Sleep Quality, Mood, and Mental Acuity
Abstract
Abstract Sleep onset depends on a decline in core body temperature, and sleep quality degrades when the thermal environment falls outside an optimal window, making active regulation of sleep surface temperature a well-supported target for intervention. Thermoregulating mattress covers are now a rapidly growing consumer category. Across published evaluations of this device class, the significant findings are concentrated in subjective measures of perceived sleep quality and daytime functioning. These devices are conspicuous in use, which leaves such measures critically exposed to expectancy bias. To date, no study of this device class has attempted to decouple the reported benefits from expectancy by means of an effective sham control. We studied 14 healthy adults over two consecutive 7-night periods on a programmable thermoregulating mattress topper: in the first the device reproduced the sounds, displays, and timing of active operation without altering surface temperature; in the second it was fully operational. Participants completed a morning self-report survey, and sleep was recorded nightly by a continuous physiological monitoring device. Against sham, active regulation improved perceived sleep quality by 8.9% (p = 0.019), restedness by 9.3% (p = 0.046), mood by 11.4% (p = 0.049), and mental sharpness by 14.0% (p = 0.007). Objective measures moved favorably on sleep continuity without reaching significance; the largest was a 20.1% reduction in sleep onset latency (− 4.6…
