Why San Francisco Residents Are Upgrading Their Labs

Many individuals in California are turning to preventative testing for three main reasons:

  1. Find Answers Standard bloodwork can miss issues like thyroid, hormone, or autoimmune problems.
  2. Longevity Optimization: You cannot optimize what you do not measure. Function tracks APOB, Insulin, and Cortisol to measure aging.
  3. Family History: Early detection of cancer signals or heart disease risk factors is possible.

San Francisco’s lifestyle aligns well with Blue Zone principles through its inherent activity and access to nourishing food. The city’s walkability, challenging hills, and abundant parks naturally encourage daily movement, fulfilling the “Move Naturally” principle. Additionally, its rich access to fresh, local produce and a thriving plant-based culinary scene makes adopting a “Plant Slant” diet remarkably accessible.

However, the high-pressure work environment and intense cost of living pose a significant challenge to the “Down Shift” principle. Chronic stress, often a byproduct of this environment, can disrupt sleep, social connections, and overall mental well-being, demanding a conscious effort from residents to prioritize rest and stress reduction.

To fully embrace longevity, San Franciscans should proactively cultivate their “Right Tribe” and prioritize “Belong” by fostering supportive communities and intentionally scheduling downtime to counteract the city’s demanding pace.
