Adults aged 50 and older who experience both digital and social isolation at the same time have a higher risk of dying compared to those who experience only one or neither form of isolation.
Mechanism
Synthesis from 1 study
When older adults lose both human contact and access to digital tools, their bodies stay in a constant state of stress. This wears down their immune system and speeds up aging inside the body, making them more likely to get seriously ill or die sooner.
Most probable mechanism
When older adults are cut off from both people and technology, their bodies stay stuck in a high-stress state for too long. This keeps stress hormones elevated, weakens the immune system, and makes the body less able to repair itself, which over time leads to faster aging and higher risk of death.
Persistent lack of social interaction and digital connectivity reduces opportunities for positive emotional regulation and social support.
Reduced emotional regulation leads to sustained activation of the hypothalamic-pituitary-adrenal (HPA) axis, resulting in chronically elevated cortisol levels.
Elevated cortisol suppresses immune cell function and promotes systemic low-grade inflammation.
Chronic inflammation and reduced immune surveillance impair tissue repair, increase vulnerability to infection, and accelerate age-related physiological decline.
