这项工作评估的重要性，睡眠对情绪和认知后24？h暴露于缺氧。10名男性，年龄2330岁，被放置在常压室模拟海拔4,500？M.睡眠评估从22：006：00进行，所有的情绪和认知评估进行20？醒来后的一分钟评估进行了常氧条件下，24？h缺氧。睡眠被重新评估14？h后开始暴露于缺氧条件下，情绪状态和认知功能进行了重新评估24？h后开始暴露于缺氧条件。缺氧减少了总睡眠时间、睡眠效率、慢波睡眠和快速眼动。抑郁情绪，愤怒和疲劳增加缺氧条件下。活力、注意力、视觉和工作记忆、注意力、执行功能、抑制控制和心理处理速度都恶化了。睡眠模式的变化可以调节24岁以后的情绪和认知能力？H.
This work evaluated the importance of sleep on mood and cognition after 24?h of exposure to hypoxia. Ten males, aged 2330 years, were placed in a normobaric chamber simulating an altitude of 4,500?m. Sleep assessments were conducted from 22:006:00; all mood and cognitive assessments were performed 20?min after awakening. The assessments were conducted in normoxic conditions and after 24?h of hypoxia. Sleep was reevaluated 14?h after the start of exposure to hypoxic conditions, and mood state and cognitive functions were reevaluated 24?h after the start of exposure to hypoxic conditions. Hypoxia reduced total sleep time, sleep efficiency, slow-wave sleep, and rapid eye movement. Depressive mood, anger, and fatigue increased under hypoxic conditions. Vigor, attention, visual and working memory, concentration, executive functions, inhibitory control, and speed of mental processing worsened. Changes in sleep patterns can modulate mood and cognition after 24?h.
