非稳态负荷(allostatic load)概念如何解释慢性压力导致疾病的路径?
How does the concept of allostatic load explain the pathway from chronic stress to disease?
McEwen 指出,机体通过交感神经与 HPA 轴的反复激活来适应压力,但应激反应若过于频繁或迟迟不能关闭,就会累积为生理损耗,即非稳态负荷。其表现包括血压、皮质醇与炎症标志物持续偏高以及调节弹性下降。纵向研究发现它能预测心血管疾病和认知衰退,已成为生物行为医学的核心测量指标之一。
McEwen argued that the body adapts to stress through repeated activation of the sympathetic nervous system and the HPA axis, but responses that fire too often or fail to shut off accumulate as physiological wear and tear — allostatic load. It shows up as chronically elevated blood pressure, cortisol, and inflammatory markers alongside declining regulatory flexibility. Longitudinal studies link it to cardiovascular disease and cognitive decline, making it a core measure in biobehavioral medicine.

面对压力，人们常用的应对方式有哪些？
What coping styles do people commonly use under stress?
拉扎勒斯区分问题聚焦应对（直接解决压力源）与情绪聚焦应对（调节情绪反应），此外还有回避、求助等策略。不同情境下有效方式不同。
Lazarus distinguished problem-focused coping (directly tackling the stressor) from emotion-focused coping (managing emotional reactions), plus strategies like avoidance and seeking support. Different situations call for different approaches.

压力激素“皮质醇”对身体有什么影响？
How does the stress hormone cortisol affect the body?
面对压力时，肾上腺释放皮质醇以提升血糖、调动能量应对威胁。短期有益，但长期过高会损害免疫、睡眠和记忆，并增加慢性病风险。
Under stress, the adrenal glands release cortisol to raise blood sugar and mobilize energy against threat. Short-term it helps, but chronically high levels harm immunity, sleep, and memory and raise chronic-disease risk.

睡眠中的REM（快速眼动）阶段有什么特别？
What is special about the REM (rapid eye movement) stage of sleep?
REM睡眠时眼球快速转动、脑电接近清醒状态，绝大多数生动梦境发生在此阶段，对身体恢复和记忆巩固十分重要。每晚REM会多次出现并逐次变长。
During REM sleep the eyes dart rapidly and brain activity resembles wakefulness; most vivid dreams occur here, and it is important for physical restoration and memory consolidation. REM recurs several times nightly, lengthening each time.

慢性压力通过下丘脑—垂体—肾上腺轴(HPA轴)损害身体健康的机制是什么?
What mechanism links chronic stress to physical illness through the hypothalamic-pituitary-adrenal (HPA) axis?
持续的压力刺激使HPA轴反复激活,皮质醇水平长期偏高,从而抑制免疫细胞活性并升高血压。对照实验进一步发现,高应激志愿者在暴露于感冒病毒后的发病率显著更高,说明心理应激能够转化为可测量的躯体后果。
Sustained stress repeatedly activates the HPA axis, keeping cortisol chronically elevated, which suppresses immune-cell activity and raises blood pressure. Controlled experiments further found that highly stressed volunteers developed markedly higher infection rates after exposure to common-cold viruses, showing that psychological stress translates into measurable bodily outcomes.

健康信念模型认为哪些心理因素共同决定了一个人是否采取疫苗接种或癌症筛查这类预防性行为?
Which psychological factors does the Health Belief Model hold jointly determine whether a person adopts preventive actions such as vaccination or cancer screening?
健康信念模型的核心变量包括感知易感性、感知严重性、感知益处、感知障碍以及触发行动的线索。该模型预测,当个体估计疾病威胁较大且行动收益超过成本时,更可能去接种疫苗或参加筛查。后来补充的自我效能成分进一步解释了人们能否启动并维持这些行为改变。
The core variables of the Health Belief Model are perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action. It predicts that people are more likely to get vaccinated or attend screening when they judge the disease threat to be sizable and the benefits of acting to outweigh the costs. A later addition of self-efficacy further explains whether people can initiate and maintain such changes.

为什么人需要睡觉？
Why do people need to sleep?
睡眠帮助身体修复、巩固白天的记忆，并清理大脑代谢废物。长期缺觉会损害注意力、情绪和免疫力，儿童和青少年尤其需要更多睡眠。
Sleep helps the body repair, consolidates the day's memories, and clears metabolic waste from the brain. Chronic sleep loss harms attention, mood, and immunity; children and teens need especially more sleep.

什么是“安慰剂效应”？
What is the placebo effect?
安慰剂效应指仅因相信治疗会有效（如服用无药效的糖丸）而出现真实症状改善的现象。它说明心理期待能影响身体的感受与恢复。
The placebo effect is a real improvement in symptoms caused merely by believing a treatment works, such as taking a sugar pill. It shows that psychological expectation can influence bodily sensation and recovery.
