概括
连贯感 (SOC) 保护工人免受长时间工作导致的睡眠损失. 与延长工作时间相关的总睡眠时间 (TST) 的较高SOC缓冲,特别是对于那些无法减少工作时间的人来说.
科学领域:
- 职业健康问题
- 睡眠医学
- 心理学
背景情况:
- 长时间工作是睡眠时间缩短的已知风险.
- 一致感 (SOC) 可以缓冲与工作有关的压力影响睡眠.
- 之前关于SOC和睡眠时间的研究使用了主观措施,缺乏客观数据.
研究的目的:
- 调查SOC和长时间工作时间在客观测量的总睡眠时间 (TST) 之间的相互作用.
- 测试假设较高的SOC降低了长时间工作导致睡眠减少的易感性.
主要方法:
- 对日本工人的横截面调查 (2016-2017).
- 通过SOC-13尺度和自报告的每周工作时间来评估SOC.
- 客观测量TST使用动图一周;长时间工作时间定义为≥50小时/周.
- 使用多重回归分析来检查长时间工作时间和TST上的SOC之间的相互作用.
主要成果:
- 分析了540名工人 (平均年龄为43.2岁,女性为41.1%).
- 长时间工作 (≥50小时/周) 报告了56.3%的参与者.
- 长时间的工作时间显著减少了TST13.5分钟/晚 (P=.023).
- 在TST上,长时间工作和SOC之间发现了显著的相互作用 (P=.026).
- 由于长时间工作而增加的低SOC睡眠减少 (β=-24.7,P=.0015).
结论:
- 较高的SOC减轻了与长时间工作相关的睡眠损失.
- 有较低SOC的个人在苛刻的工作时间表下经历了更大的TST减少.
- 加强SOC的干预措施可以保护工人的睡眠健康,尤其是在减少工作时间是不可行的情况下.

01:24Substance Use Disorders Affecting Sleep
216
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:13Insufficient Sleep and Sleep Deprivation
210
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:19Management of Insomnia
320
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:11Understanding Sleep
502
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.

02:20Longitudinal Research
12.4K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
