The awareness of the importance of healthy sleep is increasing in the community, hence many devices were developed in the last decade to help recognize sleep architecture. Studies that assessed the matching between sleep rings and iOS systems in apple watches are limited. We aimed to show that the Apple watch can be a useful tool in evaluating sleep architecture for many sleep disorders by comparing it with sleepimage rings. We conducted home sleep studies on 1 participant for 7 nights using SleepImage rings and Apple Watch Series 7 with sleep health simultaneously. The participant is a healthy 32 year old male. N1, N2 and N3 stages of sleep were clumped together as NREM in the apple watch for comparative data. Data collected included total sleep time (TST), time in bed (TIB), time in REM, and time in NREM. Data was analyzed with IBM SPSS v. 29.0.0 using descriptive statistics. Mann Whitney test for comparison with p< 0.05 considered significant. Data in minutes included mean TST with watch 408.7, standard deviation (SD) 44.3 and with ring 404.57, SD 47.1 (p=0.902). Total NREM sleep with watch 330.1, SD 32.8 and with ring 337.8, SD 42.3 (p=0.620). Total REM with watch 72.7 SD 19.5 and with ring 66.7 SD 13.1 (p=0.535). Total TIB with watch 475.3 SD 20.8 and with ring 421.4 SD 52.8 (p= 0.017). We found no statistically significant difference between the sleep ring and apple watch in estimating TST, REM-sleep and non-REM sleep. The only measurement that was significantly different is the time in bed. This report suggests that Apple Watch can be used as an adjunctive tool for sleep architecture for treating sleep disorders.
