Physical Inactivity Leads to Earlier Ageing

Feb 04, 2008

The latest research shows that sedentary way of life is not only an enemy to your health, leading to age-related diseases, but also one of the major factors contributing to early ageing.

The study published in the Archives of Internal Medicine analyzed physical activity level, smoking habits and socio economic level of 2,401 twins. The results showed that physically active people had lower rates of development of many diseases, including cardiovascular disease, type 2 diabetes, cancer, high blood pressure, obesity and osteoporosis than those who led sedentary way of life.

Scientists also concluded that physically inactive people had shortened leukocyte telomeres - markers of biological age. Telomeres are areas of highly repetitive DNA at the end of a linear chromosome in leukocytes. Physical inactivity causes oxidative stress that leads to destructive processes in cells, speeding up ageing process.

Physical activity otherwise contributed to less stress and lessened its effect on telomeres and the aging process.
