New research suggests that social interaction may help reduce the risk of frailty later in life.
researcher From Newcastle University Data from more than 2,000 men over the age of 65 who were assessed eight years apart were examined.
Participants were asked questions about their social lives, including descriptions of time spent with friends and family, volunteering, religious or social clubs, vacations, and reading.
The results showed that people with high social engagement at the start had a 31% lower risk of frailty, while those who increased their social activity over an eight-year period saw a 23% lower risk.
These findings highlight how social connections can have massive benefits on our physical health, especially in later life, but what impact might staying connected have on our brains?
We spoke to consultant neurologist Dr Steven Elder Rejuvenating HealthWho gave some information on this topic…
Can staying social later in life help prevent cognitive decline?
“Maintaining strong social connections later in life may help reduce cognitive decline by keeping the brain active and adaptable,” explains Elder. “When we connect socially, we stimulate many areas of the brain responsible for language, memory, attention and emotion.
“This ongoing stimulation encourages the formation of new neural pathways, a process known as neuroplasticity, which helps preserve cognitive function and flexibility as we age.”
What effect can social interaction have on our memory?
sociability Neurologists say it may play an important role in supporting and even enhancing memory later in life.
“Meaningful conversation connects many parts of the brain together, from areas that process language and emotions to areas that store and retrieve information,” explains Elder. “When we talk, listen and share stories, we are essentially giving the brain a workout, activating the hippocampus and prefrontal cortex, which are important for forming and retaining memories. This constant stimulation helps maintain neural connections and may even encourage the growth of new ones.
“Research has shown that older adults with frequent social interactions perform better on memory and cognitive tests, suggesting that an active social life may help maintain mental acuity and slow age-related decline.”
Can socialization help improve any other cognitive process?
“Beyond memory, socialization supports executive functions like attention, problem-solving, and decision-making,” says Elder. “Connecting with others challenges the brain to adapt, process information quickly, and manage multiple stimuli, similar to cognitive training exercises.
“Regular social activity helps preserve these skills, which are essential for maintaining independence and everyday functioning.”
Can regular social engagement help reduce the risk of dementia?Neurologists highlight how growing evidence suggests regular social engagement is linked to a lower risk of developing dementia.
He explains, “Social interaction stimulates the brain in the same way as mental exercise, keeping neural circuits active and adaptive.” “It also helps regulate stress hormones and reduce chronic inflammation, both of which are linked to an increased risk of cognitive decline.
,People People who maintain close relationships and frequently engage in social or community activities are more likely to remain physically active, mentally stimulated, and emotionally balanced, all of which contribute to long-term brain health. Although social interaction alone cannot prevent dementia, it is an important part of an overall prevention strategy, along with a balanced diet, regular exercise, good sleep, and lifelong learning.
What effect can social interactions have on our mood and stress levels?
Positive social interactions, especially face-to-face, trigger the secretion of happy hormones, promoting feelings of trust, connection, and happiness.
“Positive social interaction releases oxytocin and endorphins. Hormones that promote relaxation, reduce cortisol levels and improve mood,” says Elder. “Feeling connected also provides emotional support during stressful times, protecting the brain from the harmful effects of long-term stress, which is known to impair cognitive performance.”
Can social interaction have a positive impact on our mental health in later life?
Neurologists say maintaining an active social life at all stages of life can have a profound positive impact on mental health. “Regular interactions with friends, family and community provide emotional support, reduce loneliness and strengthen a sense of belonging, all of which are essential for psychological well-being,” says Elder. “Social connections stimulate the release of mood-enhancing neurotransmitters like serotonin and oxytocin, which help regulate stress and promote feelings of peace and happiness. They also encourage purpose and routine, which are important factors in maintaining mental resilience as we age.
,studies Older adults who remain socially connected have consistently been shown to have lower rates of depression and anxiety, greater life satisfaction, and improved overall quality of life compared to those who remain socially isolated.
