I used to brag about running on five hours of sleep. Engineering hustle culture trained me to. Sleep was the thing I cut when there wasn't enough day. I wore the bags under my eyes like a badge.
That bill came due in my late forties. Brain fog. A1c creeping. Mood shorter than it should be. Belly fat that wouldn't budge no matter how clean I ate or how many steps I logged. Turns out you can out-train a bad diet for a while. You cannot out-train bad sleep. Not at 51.
So I started treating sleep the way I treat any production system at work: measurable, monitored, and protected.
What I had to unlearn
Sleep is not a luxury. It's where 80% of the actual repair work happens. Your liver clears glucose, your brain takes out the trash (literally — the glymphatic system flushes metabolic waste), your hormones rebalance, your muscles rebuild. Skip sleep, and none of the other Wellness Threads work as well. Nutrition, exercise, mood — all downstream of sleep.
Six hours is not the new eight. That study you remember reading? Cherry-picked. The data is brutal: consistent sleep under 7 hours raises insulin resistance, blood pressure, and all-cause mortality. I needed to stop arguing with the data.
Quality > quantity, but quantity is the floor. You can't be a four-hours-of-deep-sleep ninja. The body needs the full cycle — light, deep, REM, repeat — and that takes time.
What I changed
A hard wind-down at 09:00pm. Phone goes face-down. Laptop closed. Lights dim. This is the single biggest lever I pulled. Without a wind-down, midnight just happens to me.
Same wake time, every day. Including weekends. 5:00am. Yes, weekends too. Your circadian rhythm doesn't know it's Saturday. The two-hour weekend sleep-in I used to "earn" was wrecking my Monday.
No food after 6pm. Late eating wrecks sleep architecture and parks glucose right where I don't want it parked. This one was hard — Indian dinner culture is late. I shifted my dinner to 5pm and it changed everything.
Cool, dark, boring bedroom. 65–67°F. Blackout curtains. No TV. No work. The bedroom is for sleep and intimacy, not for the second monitor.
Caffeine cutoff at noon. Caffeine has a 6-hour half-life. The 4pm chai I used to love was still in my system at 10pm pretending I wasn't tired. Lying machine.
What it's done
I now sleep 7.5 hours most nights. Not perfect. Way better than where I was.
The downstream effects surprised me. Less hunger. Less sugar craving in the afternoon. Better focus in 1:1s. Less reactive in tense meetings. My A1c dropped a tick within a month of fixing my sleep, and I hadn't changed anything else yet.
The honest part
I still mess this up. Travel breaks me. A late call with the West Coast breaks me. A Sunday-night anxiety spiral breaks me. I'm not preaching from the mountain — I'm reporting from the climb.
But the climb has a clear direction now. Protect the sleep. Everything else gets easier.
This is one of four Wellness Threads I'm building my health around. The others: Cellular Nutrition, Adequate Exercise, Emotional Wellness. The full framework is on the blog.
