Maintaining close friendships over years could protect your physical health as much as your mental wellbeing.
In brief
Maintaining close friendships over years could protect your physical health as much as your mental wellbeing. Strong, lasting friendships are linked to slower biological aging and lower inflammation, making them as important for health as diet and exercise. Originally reported by Psychologies.
Friendship gets scientific recognition
Long overlooked, friendship is finally being studied seriously. The bonds we form throughout life shape our journey far more than we realize.
Friends may slow biological aging
A study in Brain, Behavior, and Immunity found that people with strong social ties show biological markers of slower aging and less inflammation.
Quality matters more than quantity
Researchers analyzed 2,000 middle-aged Americans, measuring cumulative social advantage: emotional support, family ties, community engagement, not just friend count.
Blood tests reveal the connection
People with stronger social networks showed slower biological aging and fewer inflammatory markers, which are linked to chronic diseases.
Harvard study confirms the pattern
A 90-year Harvard study found relationship quality at age 50 predicted health at 80 better than standard medical indicators.
“Prendre soin de ses relations est aussi une manière de prendre soin de soi.”
Friends encourage healthy habits
Friends push us to go out, move more, and talk through stress. These interactions may reduce inflammation, boost immunity, and preserve cognitive abilities.
What to remember
Strong, lasting friendships are linked to slower biological aging and lower inflammation, making them as important for health as diet and exercise.
