I was so obsessed with building apps I forgot how to sleep — a 2,000-year-old clock fixed it
Burnout, insomnia, surfing, and the ancient meridian clock that became a habit.
As a developer, I have a confession: I used to forget time entirely. When I was deep in code, hours vanished. Dinner at midnight. Bed at 3am. I'd look up and realize I'd been sitting for eight hours straight.
I told myself it was necessary — "just push through, ship it, then rest." I wanted everything: to keep building, to keep surfing, to read the business books I never had time for. So I extended my working hours. And the result wasn't more output. It was burnout and insomnia.
The insomnia was the worst part. I'd lie awake at 3am, wired, unable to sleep. I know I'm not alone — so many people struggle with sleep that they turn to medication, and it still doesn't fix the root cause.
The insight
Then I started reading the Huangdi Neijing (the Yellow Emperor's Classic of Medicine) — an ancient Chinese text most of my friends have never heard of (worth a quick Wikipedia read if you're curious). And I found the 子午流注 — the meridian clock.
It divides the day into twelve two-hour windows, each tied to a different organ system, each with clear "do / don't" guidance. And it explained, with uncomfortable precision, everything I'd been doing wrong:
- Modern office life crams eight hours of intense work into one block, with no regard for when the body actually peaks.
- People exercise hard at the wrong times — strenuous exertion right when the body needs to rest.
- Bedtime and wake time are off, so sleep quality quietly collapses.
The ancient wisdom is simple: if you live in tune with your body's natural clock, a lot of health problems resolve themselves — and your work output improves, not despite the balance, but because of it.
Trying it myself
So I rebuilt my day around the meridian clock:
- 卯时 (5–7am) — rise, warm water, gentle Tai Chi / Ba Duan Jin.
- 巳时 (9–11am) — surf when there are waves, train when there aren't; otherwise, focused coding.
- 未时 (1–3pm) — my best deep-work window for coding.
- 申时 (3–5pm) — the second exercise window: surf or strength training.
- 酉时 (5–7pm) — light dinner, then sit quietly to settle the mind.
- 戌时 (7–9pm) — read. Finally, the books I never had time for.
- 亥时 (9–11pm) — wind down for real sleep.
It worked. Genuinely. Better sleep, clearer focus, more balanced days — and I still get to code and surf.
Why Meridian speaks to you
The voice reminders are what make it stick. Meridian doesn't just ping — it speaks. At each hour it gently tells you what your body is best at and what to avoid, like a quiet teacher. It's not nagging you to check a box. It repeats the rhythm, hour by hour, until you know it by heart — until you don't need the app anymore.
So I built Meridian — an app that puts this 2,000-year-old clock on your phone. One-time purchase. No subscription, no account, no ads. Everything stays on your device.
Your body already has a schedule. I just made an app that shows it to you.
痴迷开发到忘了睡觉 —— 一个 2000 年前的时钟治好了我
过劳、失眠、冲浪，以及那个古老经络时钟如何变成我的习惯。
作为一个开发者，我必须坦白：我曾经完全忘记时间。沉浸在代码里时，几个小时转瞬即逝。凌晨才吃晚饭，三点才上床。一抬头才发现，自己已经连续坐了八个小时。
我告诉自己这是必要的——「再撑一下，发布完就休息」。我什么都想要：继续开发、继续冲浪、读那些一直没时间读的商学院书籍。于是我延长了工作时间。结果不是更多产出，而是过劳和失眠。
失眠最折磨人。凌晨三点，我清醒地躺着，大脑高速运转，无法入睡。我知道自己不是一个人——太多人被睡眠困扰，甚至依赖药物，却始终解决不了根本问题。
那个洞察
后来我开始读《黄帝内经》——很多朋友没听过这部古老的经典（感兴趣可以先从维基百科了解）。我在里面找到了子午流注——经络时钟。
它把一天分成十二个时辰，每个时辰对应一个脏腑系统，各有清晰的「宜 / 忌」。它用令人不安的精准，解释了我做错的一切：
- 现代上班族把八小时高强度工作塞进一个大块，从不考虑身体什么时候才是巅峰。
- 人们在错误的时间剧烈运动——身体需要休息时却在拼命锻炼。
- 起床和入睡的时间不对，睡眠质量悄悄崩塌。
古老的智慧很简单：顺应人体的自然生物钟，很多健康问题会自然解决——工作产出反而更好，不是牺牲平衡，而是因为平衡。
亲身实践
于是我把自己的一天，重建在经络时钟上：
- 卯时（5–7点）——起床、喝温水、练太极/八段锦。
- 巳时（9–11点）——有浪冲浪、无浪健身；否则专注编程。
- 未时（13–15点）——我最适合深度编程的时段。
- 申时（15–17点）——第二个运动窗口：冲浪或力量训练。
- 酉时（17–19点）——清淡晚餐，然后静坐收神。
- 戌时（19–21点）——阅读。终于，那些没时间读的书。
- 亥时（21–23点）——真正放松，准备入睡。
真的有效。睡眠更好、专注更清晰、日子更平衡——而我依然能写代码、能冲浪。
为什么 Meridian 会「开口」
语音提醒是让它真正起作用的钥匙。Meridian 不只是弹通知——它会开口说话。每个时辰，它轻声告诉你身体此刻最适合做什么、最好避开什么，像一位温和的老师。它不是强迫你打卡，而是通过反复科普，让你逐渐记住身体自己的节律——直到你不再需要这个 App。
于是我把这个 2000 年前的时钟，做成了 Meridian。一次性买断。无订阅、无账号、无广告。所有数据都留在你的手机上。
你的身体早已有自己的作息表。我只是做了一个 App，把它呈现给你。
Your body already has a schedule. Meridian shows it to you.
