Jonathan Wolfe:本期节目探讨了良好睡眠的重要性及其对健康的影响,并采访了睡眠专家Matthew Walker教授,了解如何改善睡眠,以及睡眠如何影响身体对食物的反应。 Matthew Walker教授:睡眠分为非快速眼动睡眠(NREM)和快速眼动睡眠(REM)两种类型,不同阶段对大脑和身体有不同的作用。睡眠不足会对心血管系统、免疫系统等造成负面影响,并增加患阿尔茨海默病的风险。 睡眠不足会降低免疫力,影响抗癌细胞的生成,降低疫苗接种的有效性。睡眠不足还会导致大脑中与阿尔茨海默病相关的毒性蛋白积聚,而睡眠有助于清除大脑中的代谢废物。 睡眠、饮食和基因共同决定了人们第二天醒来后的感觉和清醒程度。充足的睡眠和富含脂肪和纤维、低糖的早餐有助于提高清醒度。基因对清醒度影响较小,而可改变的因素影响更大。 更年期会导致睡眠紊乱,随着年龄增长,深度睡眠会减少。改善睡眠的建议包括:规律的睡眠时间、保持卧室凉爽黑暗、睡前12小时避免摄入咖啡因、避免饮酒、减少屏幕使用时间等。 Matthew Walker教授:睡眠是人体最重要的生理活动之一,对学习、记忆、情绪调节、大脑可塑性以及身体各个系统都有重要作用。睡眠不足会对心血管系统、免疫系统等造成负面影响,并增加患阿尔茨海默病的风险。 REM睡眠具有情绪疗愈和学习记忆巩固的作用。深度睡眠有助于清除大脑中的代谢废物。 改善睡眠的建议包括:规律的睡眠时间,保持卧室凉爽黑暗,睡前12小时避免摄入咖啡因,避免饮酒,减少屏幕使用时间,以及根据个人生物钟类型调整睡眠时间。 咖啡因对健康的益处主要来自抗氧化剂,而非咖啡因本身。适量饮用咖啡对健康有益,但睡前应避免摄入咖啡因。酒精会干扰睡眠,应尽量避免饮酒。 更年期会导致睡眠紊乱,随着年龄增长,深度睡眠会减少。

Shownotes Transcript

We all know how good it feels to drift into deep sleep and wake up feeling refreshed. 

The positive effects of a good night’s sleep affect every aspect of our lives. We feel energetic, focused, and ready to take on the day’s challenges.  

But the long-term effects of bad sleep are less known. It turns out, they have a huge impact on our health and even how long we live.  

In this episode, Jonathan speaks with Prof. Matthew Walker to learn what the latest science says about improving our sleep — to give us more energy and better health. They also discuss whether how we sleep changes how our bodies respond to food.

- Matthew Walker) is a sleep expert, a professor of neuroscience at UC Berkeley, and founder of the Center for Human Sleep Science. He’s also the author of Why We Sleep).

Matt and his team are currently working with ZOE scientists to research the links between sleep, nutrition, and health.
