People who lack face-to-face social contact are less likely to recover from frailty compared to those who lack only digital contact, suggesting that in-person relationships matter more than online...
Mechanism
Synthesis from 1 study
Being truly lonely keeps the body in stress mode, which stops muscles and nerves from healing properly — making it harder to recover from frailty. Just having internet access doesn’t turn off that stress response.
Most probable mechanism
When someone is lonely and lacks real human contact, their body stays in a higher state of stress, which slows down healing and weakens muscle and nerve repair. This makes it harder for frail older adults to get stronger or more active again. Just having internet access doesn’t lower this stress or help the body heal.
Chronic lack of interpersonal contact activates the hypothalamic-pituitary-adrenal axis, increasing circulating cortisol levels
Elevated cortisol suppresses protein synthesis in skeletal muscle and inhibits neurotrophic factor expression in the central nervous system
Reduced muscle repair and neural plasticity impair functional recovery from frailty, including mobility and strength restoration
