What Mouth Tape Is Actually Made Of
You are putting this on your face for eight hours a night, roughly 2,900 hours a year. The backing material and the adhesive are the only two things that matter — and most brands tell you about neither.
Sleep is the north star
You get 24 hours.
Sleep decides what you do with them.
Every hour of your day is downstream of the night before. 24 North is a field guide to the full cycle — how you wake, train, eat, wind down, and breathe while you sleep — and how to set each one so the next hour gets easier instead of harder.
Evidence-first. No supplements to sell you. No sleep hacks that need a $3,000 mattress.
The premise
One day, four windows
Nothing in your day stands alone. Light in the morning sets the clock that releases melatonin at night. How you breathe at 2am sets the heart rate you wake up with. Treat the 24 hours as one system and the levers get obvious.
01
~6am — 12pm
Morningset the clock
Light, timing, and the first hour. What actually anchors a circadian rhythm, and how long you have to do it before the day drifts.

Dayspend the energy
Caffeine half-life, training windows, the afternoon dip. Where your output actually comes from and what quietly borrows against tonight.

The last four hours decide how fast you fall asleep. Light, food, alcohol, temperature, and the wind-down that doesn't require an app.

Eight hours you don't consciously control, that control everything else. Breathing, architecture, HRV, and the interventions with real evidence behind them.

From the field guide
Mouth Taping With a Beard: What Actually Sticks
Most mouth tape is designed for bare skin, and facial hair breaks the assumption it was built on. Here is why tape fails on a beard, what to look for instead, and how to take it off without the 4am eyebrow-wax experience.
When to Stop Drinking Caffeine (Work Backward From Your Bedtime)
The advice is usually "no caffeine after 2pm." That number is made up. The real cutoff depends on one thing you can calculate in about ten seconds — and for most people it lands earlier than they'd like.
What Your Recovery Score Is Actually Measuring
Your ring gives you a number out of 100 every morning. Underneath it is mostly one thing — heart rate variability — and understanding what moves it turns a mystery score into an actually useful instrument.
Pick One Wake Time and Defend It
Everyone tries to fix their sleep by controlling bedtime. Bedtime is the output, not the input. The wake time is the lever — and weekend lie-ins are jet lag you give yourself every Saturday.
How to Reset Your Clock After a Long Flight
Jet lag is not tiredness — it is your internal clock and your destination's time disagreeing. That is why sleeping it off does not work. The fix is light, timed correctly, and the direction you fly changes everything.
Why "24 North"
North is the fixed point you steer by. Sleep is that point for everything else — energy, training, mood, body composition, focus. Get it right and the other 16 hours cooperate. Get it wrong and no amount of optimizing the day makes up the difference. We write about all 24 hours, but we always navigate from the same star.
