Pattern Library
Patterns Otto observes in your data.
The patterns Otto observes are not invented. They are documented in peer-reviewed studies. Here we explain the most important ones — what they are, why they happen, what you can do with the information.
Short sleep → carb cravings the next day
After a night under 6 hours, tomorrow around 3pm you tend to reach for something sweet. Not because you want to. Because your leptin is low.
Salt at dinner → lower HRV the next morning
High sodium in the evening tends to affect overnight recovery. Your wearable sees it before you feel it.
Protein at lunch → no 3pm crash
The "3pm crash" is not fatigue. It is a glucose drop. Protein at lunch tends to prevent it.
Slightly low hydration → attention and memory affected
A 1.8% drop of body weight in water is enough to derail your day. You will not feel it as thirst.
Consistent self-monitoring → long-term maintenance
People who track their data consistently — without rigid goals — tend to maintain their progress about twice as often as those who do it sporadically.
Coffee after 2pm → fragmented sleep at night
You think a 4pm coffee does not affect you. Polysomnography says otherwise. You tend to lose about an hour of sleep — without noticing.
Alcohol in the evening → higher resting heart rate the next morning
Your heart tends to work harder overnight after 2–3 glasses. The wearable sees +3 bpm and whole nights of incomplete recovery — even at moderate intake.
Dinner less than 3 hours before bedtime → fragmented sleep
It is not the food itself that wakes you up at night. It is digestion still active when you should be recovering.
Consistent daily steps → more efficient sleep at night
You do not need sport to sleep better. You need to not sit still. 2,000 extra steps a day tend to reduce night-time awakenings significantly.
Protein at breakfast → fewer afternoon cravings
The 5pm sugar craving does not come from tiredness. It comes from a breakfast that did not set the satiety signal early enough.
Slowly declining resting heart rate → rising fitness
You do not measure VO2max at home. But your RHR over the last 6 months tends to approximate it surprisingly well — without effort, without a test.
Natural light in the morning → better mood and more aligned sleep
20 minutes outside between 7 and 10 in the morning. That is it. The effect on mood and sleep tends to be greater than that of most supplements you take.
