Episode notes
How Stress Shifts Bone Remodeling
- Bone remodeling is a continuous balance between osteoclasts (breakdown) and osteoblasts (building).
- Chronic stress and high cortisol shift that balance by increasing osteoclast activity and suppressing osteoblasts, causing net bone loss.
Cortisol Undermines Nutrition And Bone Density
- Chronic elevated cortisol reduces calcium absorption, disrupts the gut microbiome, and increases calcium loss.
- The combined effect is lower bone mineral density and higher fracture risk, particularly harmful with aging.
Loneliness Behaves Like A Physiological Stressor
- Loneliness and emotional load drive chronic inflammation and cortisol similar to physical stressors.
- Social isolation reduces motivation to exercise and eat well, creating a vicious cycle harming bone health.
