Overview

睡眠不足是指睡眠时间未达到维持最佳机能所需的建议量,即使只是略少于实际需要的时间的时间。睡眠不足可能是源于生活方式的选择,例如熬夜参加社交活动或处理工作,导致持续获得的睡眠时间少于实际所需量。例如,当身体需要 7-9 小时的睡眠时,长期每晚只睡 6 小时会对健康和整体幸福感产生累积的负面影响。

睡眠剥夺则是一种更严重的睡眠缺失形式,包括整晚不睡觉或睡眠时间大幅减少。它通常是由紧急情况引起的,例如为了准备考试或完成工作项目而"通宵熬夜"。睡眠剥夺会导致认知和身体机能的立即严重损害。

睡眠不足和睡眠剥夺都会严重影响身心健康,从认知能力到情绪稳定性等多个方面。成年人每晚需要 7 到 9 小时的睡眠才能正常运作,但许多成年人仍然无法满足这一基本需求。导致睡眠不足的各种因素,包括工作压力、社会义务以及长时间使用手机、电视和电脑等电子设备,都会因素会干扰自然的睡眠模式。

长期睡眠不足会导致一种被称为"睡眠债"的状态,即随着时间推移,睡眠不足的影响逐渐积累,降低警觉性和思维效率。仅仅一晚的睡眠不足可能会带来微妙的后果,如易怒和注意力难以集中。然而,连续几晚的睡眠不足会导致更严重的影响,包括严重的认知功能障碍,如记忆力下降、决策困难和反应时间变慢。

从生理角度来看,睡眠不足与多种严重的健康问题有关。如肥胖、糖尿病和心血管疾病的风险增加。研究表明,睡眠不足会导致应激激素和血压升高、血糖水平紊乱、以及免疫系统减弱,使人更容易感染疾病。

在心理健康领域,睡眠不足可能表现出类似抑郁的症状,并显著降低人们的整体生活满意度。认知功能(尤其是那些涉及复杂决策和道德判断的认知功能)会受到严重损害,类似于酒精中毒的影响。

为了降低这些风险,优先考虑睡眠并保持规律的作息时间至关重要。调整生活方式以提高睡眠质量,例如减少咖啡因的摄入量,并在睡前尽量避免接触电子屏幕的蓝光,也有助于改善睡眠。随着研究不断强调睡眠的重要性,越来越清楚的是,睡眠不仅仅是一个安静的夜晚,更是健康和幸福的基石。

Transcript

睡眠不足是指一个人经常睡眠不足,逐渐损害警觉性、降低注意力、增加压力水平并对健康产生负面影响。

长期睡眠不足会导致一种称为睡眠债务的状态。

例如,一个每晚持续只睡 6 小时的人可能会注意到他们的注意力逐渐下降,日常疲劳增加。

睡眠剥夺是由于在一个或几个晚上错过大量睡眠引起的,会导致直接的认知问题和健康风险,例如记忆力减退、注意力不集中以及潜在的高血压或低血压或胃酸反流,就像在通宵达旦地参加考试的人身上所看到的那样。

睡眠不足和睡眠剥夺会破坏情绪稳定,通常会增加烦躁或导致异常的沉闷。

此外,睡眠不足和睡眠剥夺会影响身体健康,例如肥胖、糖尿病和心脏病的风险。
