Episode notes
Loneliness Raises Mortality Risk
- Chronic social isolation raises mortality risk roughly comparable to heavy smoking due to long-term health effects.
- Ben Rein links this to sustained stress responses and inflammation that reduce resilience to major health events.
Isolation Triggers Chronic Stress
- The brain treats prolonged isolation like chronic stress by activating the HPA axis and elevating cortisol.
- Over time this dysregulates anti-inflammatory effects and increases chronic inflammation harming multiple organs.
Match Social Dose To Personality
- Assess whether you feel lonely or simply prefer solitude and match social dose to your temperament.
- Maintain occasional social 'watering' so your social needs don't completely dry out over time.
