Quality of sleep can be as important as quantity in reducing fatigue and sleep quality can be affected by sleep disorders. Should owners and crew managers be taking a closer look at the sleep apnea diagnosis and available treatment responses? The answer appears to be a resounding yes!
As is well documented, “fatigue degrades a person’s cognitive skills by slowing reaction time, reducing vigilance, and adversely affecting decision making, all skills necessary for effective navigation and vessel system diagnosis. Research has shown that people need about eight hours of sleep a day and receiving less than that can lead to fatigue-degraded performance. Accident investigations have linked mariner errors to their fatigue.”

疲劳和现代海员
对于减少疲劳而言，睡眠质量和睡眠时间一样重要，而睡眠质量可能受到睡眠障碍的影响。船东和船员管理人是否应该提高对睡眠窒息症诊断及现有治疗反应的关注呢？答案看来是个响亮的“是”字！
正如文献中记载的，“疲劳会延长人的反应时间，降低警惕性，影响决策力，从而降低人的认知能力，而这些都是有效导航以及诊断船舶系统故障所必需的能力。研究表明，人每天需要八小时左右的睡眠，睡眠时间少于八小时可能导致疲劳性的工作能力下降。许多事故调查结果显示，船员过失与其疲劳息息相关。”
