Regular physical activity boosts immune function by increasing natural killer cells and cytotoxic T cells production.
Being physically active aligns with human evolution, activates repair mechanisms, and preserves health with age.
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.
The Importance of Being Active as Grandparents
Being physically active, even as grandparents, is crucial as it aligns with human evolution. Grandparents historically played active roles in helping their grandchildren and maintaining food surplus. Physical activity activates repair mechanisms in the body, counteracting the effects of aging. Staying active becomes more vital as individuals age to preserve muscle, chromosome, and cell health for longevity.
Overcoming Instincts to Avoid Exercise
Human instincts, honed over millions of years, often discourage physical activity due to the historical need to conserve energy. Modern lifestyles and conveniences remove the necessity for physical exertion, making it a choice rather than a requirement. Despite the well-established benefits of exercise, many people struggle to incorporate it into their routines due to ingrained instincts. Finding ways to make exercise enjoyable, socially engaging, and necessary can help overcome resistance to physical activity.
One of the key ways to keep ourselves healthy is to stay physically active.
Feel Better Live More Bitesize is my weekly podcast for your mind, body, and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests.
Today’s clip is from episode 128 of the podcast with paleoanthropologist and Professor of Human Evolutionary Biology at Harvard University, Dr Daniel Lieberman
In this clip he explains why movement is so important for our immune system and our health, and how we can work with our biology to incorporate more movement into our life.
