Introduction Bedding can aid in maintaining a comfortable thermal state in the sleep environment. Research is needed to bring scientific rigor to document these benefits and their potential for promoting better sleep. This study examined effects of a comforter designed for warm sleepers used at home. Methods Healthy adults (96% female, ages 23-74) who reported sleeping hot, experiencing night sweats, or having hot flashes during the night participated in a 6-week field study, using a pre-post intervention design. Intervention consisted of using a comforter designed for warm sleepers, made of 300 thread count viscose from bamboo fiber with Tencel/polyester fill. During the 3-week baseline period, participants used their regular bedding. During the 3-week intervention period, they used the comforter without a top sheet to have direct contact with the comforter. Sleep was measured objectively using SleepScore Max every night and by daily and pre-post self-report. Multilevel regression and paired t-tests were used to test for statistical significance. Results There were over 1,000 nights of tracked sleep across all participants. In the full sample (n=31), self-reported sleep (e.g., perceived sleep quality, feeling well-rested) but not objectively-measured sleep showed improvements. Therefore, and given that this type of product may provide the most benefit for sleepers in midlife or older, additional analyses were conducted for the subgroup of participants who were 45 years old and above (n=15). Results indicated increased time in bed (+11 minutes, p=.017), total sleep time (+12 minutes, p=.010), and deep sleep (+6 minutes, p=.005) during the intervention compared to baseline. Improvements also were observed in SleepScore, a measure of overall sleep quality (p=.002), and BodyScore, a measure of deep sleep (p=.002). Conclusion Self-reported but not objectively-measured sleep improved among healthy adults using a comforter designed for warm sleepers. However, looking specifically at those aged 45 and older, objectively-measured time in bed, total sleep time, deep sleep, and overall sleep quality all increased significantly when using the comforter compared to baseline.

Introduction The myriad of anecdotal claims about the benefits of different pillow types may complicate consumers’ ability to find a pillow that can support better sleep. Services that provide consumers with personalized recommendations may address this problem. This study examined the sleep of research participants using pillows selected during an in-store pillow fitting process compared to using their original pillows. Methods Healthy adults (71% female, ages 21-59) who reported interest in a new pillow participated in a 9-week field study using a pre-post intervention design. The intervention consisted of being guided through the Mattress Firm in-store pillow fitting process to be paired with a pillow that provided the best fit and support based on body type and sleeping position preferences. During the 4-week baseline period, participants used their regular pillow. Once they were fit for their new pillow, participants slept with that pillow for 5 weeks, including a 1-week adjustment period. Sleep was measured objectively using SleepScore Max every night and by daily and pre-post self-report. Multilevel regression and paired t-tests and were used to test for statistical significance. Results There were 722 nights of tracked sleep across participants (n=17). Objective sleep measurements showed nightly improvement in SleepScore, a measure of objective sleep quality (p=.003), longer time in bed (+13 minutes, p=.034),longer sleep duration (+16 minutes, p=.010), a lower proportion of the night awake after falling asleep (p=.009), and better sleep maintenance (p=.009). In addition, participants got more deep sleep (+5.6 minutes, p=.017) and showed improved BodyScore, a measure of deep sleep (p=.031). Self-reported measures showed improvements in pillow comfort and overall comfort in bed; perceived ability to sleep through the night; perceived reduction in number of awakenings and amount of time awake at night; better overall sleep quality; and feeling more well-rested in the morning when using the fitted pillows compared to baseline (all ps Conclusion Objective and self-reported sleep improved among healthy adults using a pillow selected by an expert, in-person pillow fitting process. The results suggest that a pillow fitting process can improve sleep by helping individuals find a pillow that provides a personalized fit and optimal comfort. Support (If Any) Mattress Firm INC

Introduction This study examined if a diffused fragrance used at home before bedtime would contribute to sleep improvement in a sample of healthy females. Existing evidence regarding the sleep-promoting properties of fragrances often has been anecdotal or based on clinical research, thereby limiting the generalizability and ecological validity of results. Methods 26 women with self-reported interest in air care to support healthy sleep participated in a 9-week field study. A within-subjects, counterbalanced intervention design was implemented, comparing 3 weeks of nightly product use to 3 weeks without using the product after a baseline period. Intervention consisted of the use of a fragrance diffuser and fragrance by Reckitt’s Scientific Platform Fragrance Research for at least an hour at the participants’ preferred settings in the room where they spent the most time before going to bed. Sleep was measured objectively with SleepScore Max every night. Self-report data were collected at bedtime, in the morning, and after each measurement period. Multilevel regression and paired t-tests were used to test for statistical significance. Results Across all participants there were 835 nights of tracked sleep. Participants (100% female, age 21 to 55, average 36 years old) showed improvement in both objective and perceived sleep during the intervention. Participants got more deep sleep, spent a greater proportion of the night in deep sleep, and had an improved BodyScore, a measure of deep sleep (ps Conclusion Using the fragrance diffuser before bed may contribute to improvement of many aspects of sleep within this study population of females without underlying sleep conditions. Objectively improved sleep outcomes were supported by self-report, showing multifaceted benefits of the diffused fragrance on sleep. Support (If Any) Reckitt
