The tracker isn't the doctor

Sleep doctors have a name for people whose sleep got worse while they tried to perfect a tracker score: orthosomnia, roughly "correct sleep". The name comes from a report on three patients. In each, worry about the numbers had become part of the problem. Evidence: worth trying

Three people is a story, not a study. But if the morning score decides your mood for the day, try a week without it.

If the data worries you, take the worry to a doctor, not to the app.
