American scientists have found that regular communication with loved ones and friends can slow down the aging process and keep the mind sharp for years. The study, supported by the National Institute on Aging, was led by psychologist Susan Charles from the University of California, Irvine, reports infohub.kz.
As part of the project, researchers plan to analyze data from the large-scale MIDUS study, which involved more than 2,900 adults aged 24 to 97. They will examine participants' diary entries collected over twenty years, as well as biomarkers reflecting health status. Special attention will be paid to cortisol levels, inflammatory markers, gene expression profiles, and indicators of biological cell aging.
According to the authors, even simple actions—like calling a friend or having lunch with a neighbor—stimulate mental activity and reduce stress levels. Accumulating over time, such interactions can slow age-related changes and reduce the risk of chronic diseases. The researchers hope to prove that social connections should become as essential a health habit as exercise and a proper diet.
