Apple Watch Series 11: Sleep Index and blood‑pressure alerts

Apple has introduced two new health features with the Apple Watch Series 11: blood‑pressure alerts and a Sleep Index that scores nightly recovery. These expand the Watch’s health toolkit and aim to give users clearer, actionable insights about their cardiovascular health and sleep quality.

Key features

• Blood‑pressure alerts: Uses machine learning to detect patterns consistent with high blood pressure over time and notify users of potential signs of hypertension.
• Sleep Index: A sleep score that evaluates sleep quality and nightly recovery, helping users understand and improve their sleep habits.
• Other highlights: Up to 24-hour battery life, 5G connectivity, more durable glass, and a thinner design with new personalization options in watchOS.

These features complement existing sensors and analyses already available on the Apple Watch, targeting users who want more detailed day‑to‑day health monitoring.
