Why San Francisco Residents Are Upgrading Their Labs
Many individuals in California are turning to preventative testing for three main reasons:
- Find Answers Standard bloodwork can miss issues like thyroid, hormone, or autoimmune problems.
- Longevity Optimization: You cannot optimize what you do not measure. Function tracks APOB, Insulin, and Cortisol to measure aging.
- Family History: Early detection of cancer signals or heart disease risk factors is possible.
San Francisco’s vibrant lifestyle naturally encourages several Blue Zone principles. The city’s iconic hills and dense, walkable neighborhoods mean residents often incorporate significant physical activity into their daily routines, embodying the “Move Naturally” principle. Additionally, the abundant access to fresh, diverse, and often plant-forward culinary options supports a healthy, whole-food diet.
However, a key challenge for San Franciscans lies in the “Down Shift” principle. The demanding, high-pressure work environment, coupled with an exceptionally high cost of living, often leads to chronic stress and a struggle to find adequate time and space for relaxation and decompression. Prioritizing mindful stress reduction and genuine downtime is crucial for residents aiming for Blue Zone longevity.
