3 years 4 months ago


Stress is a part of modern life, but its long-term effect on our health and productivity can be dramatic. Chronic stress can literally kill you, increasing your risk for heart attack and stroke by up to 50%.


Lief Smart Patch tracks and optimizes your resiliency to stress by increasing your natural heart rate variability (HRV), a biomarker of your physical and psychological health. A low HRV score is linked to anxiety, distraction and poor performance - things we'd all prefer to avoid. Yet, Lief Smart Patch can improve your HRV and train yourself to stay focused and in control throughout your day. It's safe, drug-free and has improved stress, mood, and focus for thousands of people.
