Studies from Harvard, Stanford, and other leading institutions have consistently shown that social connection is fundamental to human health. When we lack meaningful relationships:
- Stress hormones increase: Loneliness triggers the body's stress response, leading to elevated cortisol levels and inflammation.
- Sleep quality declines: People who feel lonely often experience disrupted sleep patterns, which further impacts mental health.
- Immune function weakens: Social isolation can suppress immune system function, making you more susceptible to illness.
- Brain health suffers: Loneliness is linked to increased risk of dementia and Alzheimer's disease.
