Start with the evidence, not the score
Before reading an overall summary, check the report date, recording window and sample coverage. A shorter recording, a gap in the data, a device that was not worn consistently, or a noisy environment can all limit what a report can show. Treat every chart as a record of the available data, not a complete account of the night.
Read the timeline in context
Look for timing rather than a single explanation. A timeline may show periods of sound, movement, wakefulness, or other recorded signals. Compare those periods with your own notes: when you went to bed, whether you remember waking, illness, alcohol, travel, medication changes, exercise, or anything else that could have affected sleep.
Separate observations from conclusions
A report may describe snoring, snore clusters, disturbed-breathing signals, movement or wakefulness. These are observations to review, not confirmation of sleep apnoea, insomnia, a breathing disorder or another condition. The cause and clinical importance of a pattern need appropriate professional assessment.
