Sleep staging trackers, often using electroencephalography (EEG), measure brainwave activity to accurately classify sleep into distinct stages (Light, Deep, REM). This data provides actionable insights into sleep quality, which is fundamental for cellular repair, memory consolidation, and hormonal regulation, all critical processes for maintaining healthspan. By identifying deficiencies in specific sleep stages, users can implement targeted interventions to improve overall sleep architecture.
