Why WHOOP Stands Behind Blood Pressure Insights

Unlocking human performance and healthspan starts with understanding your body better. That’s why we introduced Blood Pressure Insights, a cutting-edge feature that helps you see how your blood pressure relates to sleep, stress, recovery, and exercise. It’s a critical indicator of how you feel and perform, but until now, has been hard to measure consistently or easily.

Our Response to the FDA

WHOOP recently received notice from the U.S. Food and Drug Administration (FDA) asserting that Blood Pressure Insights should be reviewed as a medical device before being available in the United States.

We respectfully disagree.

Blood Pressure Insights is a wellness feature, not a medical device. It’s designed to help you understand how your body responds to daily life, not to diagnose or treat any condition. Wellness features like this are common in wearable technology, like tracking your respiratory rate or HRV, and provide valuable insights to support better decisions about your performance without requiring FDA clearance.

We’ve always supported responsible regulation, and we were proud to receive FDA clearance for our ECG feature. But we also believe it's critical to protect access to wellness innovation, especially when wellness tools and features help people make smarter, more informed decisions to reach their full potential.

How Blood Pressure Insights Works 

After a one-time calibration with a standard blood pressure cuff during setup, WHOOP uses your heart rate, HRV, and blood flow patterns during sleep to estimate your blood pressure each morning when your body is rested and results are most accurate. You’ll see two numbers:

• Systolic: pressure when your heart beats
• Diastolic: pressure when your heart rests

These readings can help you understand how your body responds to:

• Increased training loads
• Poor sleep
• Stressful days

WHOOP trained its model using over 32,000 sleep sessions from 11,000+ members, then validated the results against clinical readings. We stand by its accuracy, which the FDA has not questioned.

Why Blood Pressure Insights Matter

Blood pressure acts like a mirror. It reflects how your body responds to everything from exercise to life stress to recovery demands. Research shows that blood pressure plays an essential role in:

• Hydration: Paired with heart rate, blood pressure can indicate dehydration after exercise, helping guide fluid and electrolyte replacement.
• Stress & Recovery: Higher blood pressure overnight can signal that your body hasn’t fully recovered from physical or emotional stress, and may be especially informative post acute increases in training load.

Over time, learning about your blood pressure can help you make smarter decisions to optimize how you feel and perform.

The Bottom Line

Blood Pressure Insights was built to help you:

• Track how your body responds to life’s demands
• Understand how lifestyle habits impact recovery
• Stay ahead of stress, dehydration, and fatigue
• Make smarter, more confident decisions

This is a feature designed to empower you. As always, we encourage you to speak with healthcare providers for any clinical concerns.

WHOOP is proud of this innovation, and we’ll keep building tools that help you take charge of your performance, recovery, and long-term health.
