入门 · 约 25 分钟读完前置知识：实验设计基础、认知心理学常识
导读
这篇 2018 年的论文研究了通宵睡眠剥夺对新手开发者编程表现的影响，通过实验对比睡眠剥夺与正常睡眠开发者在完成任务时的表现差异。结论与已有认知一致：睡眠不足会显著损害认知能力和开发效率。
HN 关注点：HN 读者长期讨论加班与通宵文化，这篇论文用实证数据印证了睡眠对程序员生产力的直接影响，引发了对行业熬夜文化的反思。

亲历睡眠不足是高息健康债，实际睡眠时间比躺床时间少约一小时
年轻时我和很多人一样，把通宵当作用来炫耀的事。现在我把睡眠不足视为一种以'鼻血级复利'偿还的严重健康债。睡眠不足时，日常生活会变复杂，简单任务也可能变得危险——累的时候下楼梯一定要扶扶手！另外我的睡眠追踪器显示，要在床上多待约一小时才能获得 X 小时实际睡眠：需要 8 小时睡眠就得躺 9 小时左右。我目标是 7 小时睡眠（在床上 8 小时）。

When I was younger, like many people, I thought of all-nighters as a thing to brag about. Now, I see sleep deprivation as a serious health debt that you pay nosebleed compound interest rates on. If you get less than your preferred amount of sleep, everyday living can become more complicated. Simple tasks can become dangerous. Do not walk down stairs without holding the hand rail if you are tired! Also, my sleep tracker confirms that, on average, it takes about one hour more of being in bed to get X hours of sleep. So if you need 8 hours of sleep, you need to be in bed around 9 hours! I aim for 7 hours (8 hours in bed).
亲历用手环追踪深睡，发现深夜处理工作邮件最伤睡眠质量
最近买了个便宜手环，主要看'每日深睡时长'。几个月下来我总结出影响睡眠质量的因素：吃得太晚——不好；喝东西太晚——一杯啤酒其实没那么糟；半夜还在回工作邮件——非常糟糕（哪怕喝着洋甘菊茶、听着细雨）。深睡 30 分钟和 3 小时以上的差别巨大，白天状态好、效率高、耐心也长。这可能是花得最值的 30 美元。

I've bought recently one of those cheap wrist bands. One of the most important features for me was ability to measure sleep quality in terms of "daily hours of deep sleep," whatever that scientifically means. Over the course of several months, I've been able to identify things which affect my sleep quality: * eating late: bad * drinking late: one beer... not really that bad * answering work emails until midnight: REALLY BAD (even while drinking soothing chamomile tea during soft rain) etc. I'm trying as reduce as many "bad" things as possible as I can feel a huge difference between 30 mins and 3+ hrs of deep sleep, as measured by the device. I feel much better during the day, can work more productively and, most importantly, my "fuse" seems to be much longer. Probably best $30 ever spent. (still missing weekend code binges of early 20s, though :/ )
补充除了睡眠还需要主动休息，应推动行业重视这一议题
我是创业公司的程序员。请像我一样和身边的工作狂同事聊聊这个话题，我们需要建立行业标准。睡眠对成功和幸福至关重要，而我最近发现光睡够还不够，还需要休息——如果缺乏放松，不管睡多久我都会连续疲惫好几天。

Programmer in a start-up here. Please do talk about this with your workaholic colleagues as I did! We need to create an industry standard here. Sleep is super important to success and happiness, and I just recently found that sleep is not enough. I need also rest. If I don't have rest and relaxation often I get tired for several days regardless of sleep time. Writing this after deliberate 5 minutes downtime.
支持睡眠不足损害认知早有定论，关键是通过设定工作边界来保护睡眠
这个结果并不意外：已有大量研究表明睡眠剥夺会降低认知能力。那程序员为什么还是睡不够？往往是因为工作时间太长，为了给生活留出时间只能压缩睡眠。如果你是这样，其实不必如此：你可以在工作中设定边界、学会对老板说不——而且这其实是在帮雇主，因为你的产出会提高。

This isn't a very surprising result: there's a whole body of research showing sleep deprivation reduces cognitive abilities. So why do programmers still sleep less than they need to? Often it's because they're working long hours, and to get time for the rest of their life they cut back on sleep. If that's you—it doesn't have to be that way. You can set boundaries at work (https://codewithoutrules.com/2019/04/03/setting-boundaries-at-work/), you can say no to your boss (https://codewithoutrules.com/2018/08/16/how-to-say-no/)... and you'll be doing your employer a favor because your output will go up.
