Eight and a half hours’ sleep. Fifth night running. Solid rest on paper. Woke up feeling like I’d barely slept at all.
Day 63 of tracking this. I’ve been chasing the magic number — seven hours, eight hours, eight and a half. Got them. Five consecutive nights. Should feel brilliant. Don’t.
Here’s what the data’s showing me: duration isn’t everything. I went to bed at 1am. Woke at 9:30am. The hours were right. The timing was completely wrong. And your body knows the difference.
The Hours Were Right, The Timing Was Off
Your body runs on rhythm, not just rest. The circadian clock doesn’t care that you logged eight hours. It cares when those hours happened.
Go to bed at 1am, and even with solid duration, your liver’s running its detox shift at the wrong time. Your cortisol curve is off. Your hormones are confused. The whole system’s out of sync.
I felt foggy all day. Not exhausted — just not sharp. A three-hour drive in the middle of my eating window didn’t help. But the late bedtime? That’s the real culprit.
The food stayed clean. Red pepper soup with nine plants. Creamy pork casserole, homemade. Rye crackers with pâté. Seventeen plants total, nearly 50 grams of fibre. Nutrition was solid. Sleep timing let me down.
What Circadian Research Actually Shows
This tracks with everything I’ve read. Professor Debra Skene’s circadian research is clear: when you sleep matters as much as how long.
A 10pm-6am eight hours beats a 1am-9am eight hours. Even though the number’s identical.
Your body has a preferred schedule. Liver function peaks at certain times. Hormone production runs on a clock. Cortisol should drop in the evening and rise in the morning. Melatonin does the opposite.
When you shift your sleep window late, you’re asking your internal systems to work overtime at the wrong shift. They do it. But they complain.
What This Means for Your Own Sleep
Lesson learned. Again. Rhythm isn’t just about eating windows. It’s sleep timing too.
Same bedtime, same wake time — that’s what the body wants. Consistency over raw duration.
Tomorrow’s a fasting day. Tonight? Bed before midnight. Non-negotiable. Because five nights of good hours mean nothing if the timing’s still off.
Track your own rhythm. Note when you go to bed, not just how long you sleep. The pattern matters more than the number.
🎯 Key Takeaways
- Sleep duration ≠ sleep quality — 8.5 hours at the wrong time still leaves you knackered
- Circadian rhythm trumps sleep hours — 10pm-6am beats 1am-9am even with identical duration
- Consistency beats perfection — same bedtime and wake time matter more than chasing “8 hours”

Eight and a half hours’ sleep. Fifth night in a row of proper rest. Woke up knackered. Day 63.
Eating-window day. Six hours — longer than planned. Three-hour drive in the middle threw the schedule sideways.
Here’s what I’m learning: duration isn’t everything.
I’ve been chasing the sleep hours — seven, eight, eight and a half. Got them. Five nights running now. Should feel brilliant.
But I went to bed at 1am. Woke at 9:30. The hours were right. The timing was off.
Your body runs on rhythm, not just rest. Circadian clock doesn’t care that you slept eight hours — it cares when those hours happened. Go to bed at 1am, and even with solid duration, your liver, your hormones, your cortisol… they’re all running their shifts at the wrong time.
Felt foggy all day. Not exhausted — just… not sharp. The drive didn’t help. But the late bedtime? That’s the culprit.
Food stayed clean. Red pepper soup — nine plants in one bowl. Creamy pork casserole, homemade. Rye crackers with pâté. Seventeen plants total, nearly 50 grams of fibre. The eating was solid. The sleep timing let me down.
