Development of fatigue management solutions is critical to U.S. Navy populations. This study explored the operational feasibility and acceptability of commercial wearable devices (Oura Ring and ReadiBand) in a warship environment with 845 Sailors across five ship cohorts during at-sea operations ranging from 10 to 31 days. Participants were required to wear both devices and check-in daily with research staff. Both devices functioned as designed in the environment and reliably collected sleep-wake data. Over 10,000 person-days at-sea, overall prevalence of Oura and ReadiBand use was 69% and 71%, respectively. Individual use rates were 71 ± 38% of days underway for Oura and 59 ± 34% for ReadiBand. Analysis of individual factors showed increasing device use and less device interference with age, and more men than women found the devices comfortable. This study provides initial support that commercial wearables can contribute to infrastructures for operational fatigue management in naval environments.

疲劳管理解决方案的开发对美国海军人员至关重要。本研究探讨了商业可穿戴设备（Oura Ring 和 ReadiBand）在军舰环境中的操作可行性和可接受性，该环境中有 5 个舰艇编队的 845 名水手，在海上作业期间持续 10 至 31 天。参与者被要求佩戴这两种设备并每天向研究人员报到。这两款设备均按照环境中的设计运行，并可靠地收集睡眠-觉醒数据。在海上超过 10,000 人日的情况下，Oura 和 ReadiBand 的总体使用率分别为 69% 和 71%。Oura 的个人使用率为 71 ± 38%，ReadiBand 的个人使用率为 59 ± 34%。对个人因素的分析表明，随着年龄的增长，设备的使用量不断增加，设备干扰减少，并且男性多于女性，认为设备舒适。这项研究提供了初步支持，证明商业可穿戴设备可以为海军环境中的操作疲劳管理基础设施做出贡献。
