Stress & Aging

Chronic stress and poor recovery accelerate aging at the cellular level — affecting your hormones, immune function, and resilience. Your biological age can be years ahead of or behind your calendar age depending on how your body handles these pressures. Blood tests measuring stress hormones and aging markers show whether your lifestyle is protecting or depleting your long-term health.

Biological Age
x2

Biological age measures how your body is aging at the physiological level, independent of your birthday. Using validated algorithms based on key blood biomarkers, it calculates whether your organs and systems are functioning like someone younger or older than your chronological age. Unlike calendar age which only moves forward, biological age can improve — making it both a powerful health benchmark and a motivating target for lifestyle optimization.
