How To Review Low-Energy Windows With Hydrogen
Low-energy windows are one of the fastest ways to turn raw tracking into useful interpretation, especially when they repeat across normal workdays.

Repeated windows matter more than one-off bad hours.
Hydrogen gets stronger when you ask about recurrence, not isolated dips.
The right follow-up question is usually about what changed around the window.
Look for repetition first
A single low-energy afternoon might just be noise. A repeating low-energy window across comparable workdays is far more useful.
That is why the best first question is usually about recurrence, not explanation.
Three prompts that work
These prompts narrow the question enough for Hydrogen to work with stable patterns.
Which low-energy window repeats most on workdays?
Compare my last 10 workdays and show where energy dips cluster.
What changed before my lowest-energy window this week versus last week?
What to do after you find one
Once the window is clear, the next step is to ask what changed around it. That could be total workload, activity decline, irregular tracking, or missing wearable context.
