Illustrative ranges. Your physician sets yours.
(01) How it’s done
On the day
Seven nights of data from a ring we lend you before your day, plus a structured sleep questionnaire.
If the results suggest sleep apnoea, we arrange a home sleep study.
(02) Why it matters
What it tells us
Poor sleep raises blood pressure, blood sugar, appetite and the risk of cognitive decline.
It is the cheapest thing we can fix, and often the first part of the plan we start with.
(03) Same system
Brain & sleep
Measured on the same day, read by the same physician.
