Effects of different bed sheets on bed climate and thermal response

Abstract

Aim: The aim of this study was to investigate how bed climate changes when disposable waterproof sheets are used in addition to usual ones. Methods: Thirty healthy female students (20.1 ± 1.1 years) consented to participate in the study, and were divided into three groups (cotton sheet only, additional disposable rayon sheet, additional polyester sheet). The skin temperatures of the subjects, bed climates (bed temperatures and relative humidity) and subjective sensations were measured for 45 min. Results: Both skin and bed climate temperatures showed significant increases as time passed (P < 0.05). The humidity on disposable waterproof sheets was the highest among the three groups (P < 0.05). All subjects gradually began to feel warmer and wetter. Conclusion: These results suggest nurses should consider not only cost and convenience when they use waterproof sheets, but also bed climate. This will also help to prevent pressure ulcers.

Functional links between thermoregulation and sleep in children with neurodevelopmental and chronic health conditions

“…In their review of thermal environment and sleep quality, Lan et al (70) found that an in-bed microclimate of around 30 • C was most consistently associated with thermoneutrality for the sleeping human body, with relatively small variation across seasons and change in ambient temperatures. Various studies in adults have shown that the microclimate can be determined and indeed manipulated by types of mattresses (60,61,(73)(74)(75), bed sheets (76), personal heating or cooling devices such as electric blankets or airflow devices (77)(78)(79)(80) and clothing worn during sleep (46,81). While environment conditions, bedding and the microclimate clearly influence body temperature and perspiration, there is limited research examining the thermal comfort of children within their normal sleeping environments.…”

“…More specifically, the creation of an approximately thermoneutral microclimate of the bed is increasingly recognized as particularly important for thermoregulation and sleep, for sleep onset and protection of sleep stage structure, as described above. With the interactive effect of the ambient room environment, the microclimate of the bed is affected by materials used in the mattress, pillows, bed linen and clothing, and by presence or absence of other bodies (people or pets) in the bed ( 54 , 76 , 119 , 120 ). The increasingly diverse and sophisticated range of types and materials used for bedding and clothing, such as blankets or throws with timers and varied heating zones, and the development of “smart” materials such as phase change materials, reflects the prevailing knowledge about the importance of thermal comfort for sleep ( 121 ).…”

Objective and subjective evaluations of quilted mattress ticking fabrics for their thermal comfort performances

“…Besides main mattress structure, the upper textile components such as ticking layers, covers and bedsheets were also investigated that although features are season specific (cooler and warmer touch sensations for summer and winter in turn), common necessities of all seasons were stated as; dry contact feeling with quick liquid transfer and drying features, breathability with sufficient water vapour and air permeabilities. Effects of material (cotton, cotton/PU, cotton/PES) and structures (woven and knitted) of bed sheet fabrics on thermal conductivity and breathability in dry and wet states were investigated (Ahirwar et al ., 2020; Hes et al ., 2014; Ikeda and Fukai, 2005).…”
