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 lifestyle often aligns robustly with the “Move Naturally” and “Plant Slant” Blue Zone principles. The city’s challenging hills, extensive parks, and strong active transit culture naturally embed physical activity into daily routines. Coupled with an abundance of fresh, diverse, and plant-forward culinary options, residents are well-positioned for a diet rich in nutrients and regular movement.
However, a significant challenge arises with the “Down Shift” principle. The high-pressure tech industry, combined with an exceptionally high cost of living, can lead to chronic stress and an intense pace of life. This makes it difficult for many residents to consistently unwind, practice mindfulness, and implement the necessary stress-reduction routines vital for long-term well-being and longevity.
