Sleep quality is a different complaint from sleep quantity: the hours happen, but the morning arrives broken. Quality lives in the architecture — the proportions of deep and REM sleep — and it has specific thieves, led by alcohol and late caffeine. It also has a measurement problem: people misjudge their own sleep quality badly. This guided journey covers all three.

Health information, not a diagnosis. BodyFinds helps you explore evidence-based health information. Sleep disorders are clinical diagnoses — a sleep study is the only way to diagnose them.

When poor quality deserves a sleep study

You cannot feel your own apneas — that's the trap. Snoring, witnessed pauses, waking unrefreshed despite adequate hours, or morning headaches, together, are a sleep-study conversation, and treating apnea is among the highest-yield sleep interventions in medicine. Chronic insomnia has first-line treatment (CBT-I), not a supplement shelf. And poor sleep arriving alongside persistent low mood deserves both halves of the conversation — with a clinician.
