Idiopathic Hypersomnia. Sleep inertia and naps, finally counted.
IH is the sleep that never refreshes and the mornings you can't surface from. Leo's IH hub tracks sleep inertia, counts naps, and keeps last night's sleep in view — so the burden that's hard to describe shows up as data.
The grogginess that doesn't lift, on record.
A sleep-inertia card surfaces recent “groggy on waking” entries with severity, a naps-today card counts short sleeps and totals their time, and last night's sleep comes from your existing sleep records — including time in bed when you log it.
It reuses Leo's sleep and symptom tracking rather than building a parallel app, so an IH log is the same data the rest of Leo sees.
Inertia, naps, and night sleep.
Sleep inertia
Recent “groggy on waking” entries with a 0–10 severity, so the morning burden is visible.
Naps today
Short sleeps counted, with total nap time for the day.
Last night
Total sleep and time in bed pulled from your sleep records.
Symptoms & flares
An 8-symptom IH set — long unrefreshing sleep, brain fog, automatic behaviors — plus flare logging.
Labs
CBC, CMP, thyroid, iron, B12/folate and vitamin D come pinned, with trends and ranges.
What ships in the Idiopathic Hypersomnia hub.
Leo tracks. It doesn't diagnose.
IH is diagnosed by a clinician with sleep studies, and overlaps other sleep disorders — Leo has no screener and makes no claim about whether you have it.
Everything is descriptive and on-device-first. The cards describe what you logged; they never predict or give medical advice.
Sleep inertia and naps, on the record.
Sleep-inertia tracking, nap counts, and last-night sleep from your records — organized for the conversation with your sleep specialist.
