Why Northridge 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.

Northridge often fosters strong family and community bonds, particularly within established neighborhoods and around CSUN. This nurturing environment aligns well with Blue Zone principles of “Loved Ones First” and “Right Tribe,” providing vital social support networks crucial for emotional well-being and a sense of belonging.

A primary challenge for Northridge residents is the car-dependent lifestyle. The sprawling layout and reliance on driving for daily errands limit opportunities to “Move Naturally,” making it harder to integrate effortless physical activity into routines and potentially leading to more sedentary habits.
