Deep dives

Physical Activity and Immune System

Regular physical activity, such as a brisk walk for 150 minutes a week, significantly lowers the relative risk of mortality. Exercise boosts immune function by increasing natural killer cells and cytotoxic T cells production, which help fight infections. It also enhances antibody production, particularly beneficial for older individuals, improving their responses to vaccines. Engaging in physical activity triggers repair and maintenance mechanisms in the body, slowing aging processes and reducing the risk of diseases.
