Bedroom / sleep zone checklist

A quick walkthrough of common bedroom setups, with practical, no-cost suggestions.

How to use this checklist

Each item reflects a common, practical setup question — not a measured risk. Checking an item shows a plain-language, no-cost or low-cost suggestion; it does not calculate an exposure level. Pair this with the room explorer to plan where to measure, and the measurement log to record readings before and after a change.
