Narrative review: lifestyle strategies and age-related immune decline
This narrative review discusses physical activity, nutrition, fasting-related approaches, stress reduction and vaccination as possible modulators of age-related immune decline and chronic low-grade inflammation; it notes that longitudinal trials are still needed. [1]
Automatic summary · not editorially reviewed
The key findings
The review describes age-related immune decline as including reduced naïve lymphocytes, senescent cell accumulation, impaired function of all immune cell types and chronic low-grade inflammation. [1]
The review reports that vitamin D supplementation reduced autoimmune disease incidence by 22%, and caloric restriction lowered CRP and TNF-α by 40% and 50%. [1]
The review states that longitudinal trials are needed to define optimal intervention parameters, population-specific thresholds and long-term durability of immune rejuvenation. [1]

Immune aging features described in the review
The review describes age-related decline in immune function as reduced numbers of naïve lymphocytes, accumulation of senescent cells, impaired function of all immune cell types and chronic low-grade inflammation, called inflammaging. According to the review, these alterations contribute to greater susceptibility to infections and malignancies as well as to autoimmunity and other age-associated diseases.

Lifestyle strategies and reported inflammation markers
The article reviews lifestyle interventions that may mitigate immune aging: regular physical activity, nutritional interventions such as different diets, caloric restriction and other fasting-related approaches, stress reduction and vaccination. It reports that vitamin D supplementation reduced the incidence of autoimmune diseases by 22%, while caloric restriction led to a decrease in CRP and TNF-α by 40% and 50%, respectively. Mind-body practices and controlled cold exposure are described as promising but with limited and inconsistent evidence.

Review conclusion and need for longitudinal trials
The review concludes that integrated lifestyle strategies may slow aging-related immune decline and support healthy aging. It states that longitudinal trials are required to define optimal intervention parameters, population-specific thresholds and the long-term durability of immune rejuvenation.
