A sedentary lifestyle is a significant risk factor for numerous noncommunicable diseases, including cardiovascular diseases, cancer, and diabetes. In a comprehensive study conducted by researchers who reviewed Cochrane systematic reviews (CSRs) from the Cochrane Library, evidence was gathered on the effectiveness of exercise and physical activity in improving various health outcomes. This study spanned reviews published between 2000 and 2019, encompassing randomised controlled trials involving healthy individuals as well as those at risk or medically compromised.
The analysis included 150 CSRs covering 54 different conditions. The findings were compelling: engaging in regular physical activity resulted in a 13% reduction in mortality rates and modest improvements in quality of life (QOL). Specifically, data from 10 CSRs involving 27,671 participants showed a significant decrease in mortality risk, while 15 CSRs with 32,984 participants highlighted small yet meaningful enhancements in QOL.
These results underscore the broad benefits of physical activity across diverse populations. Exercise not only lowers the risk of death but also enhances mental and physical well-being. For instance, patients with mental health conditions experienced the most substantial improvements in QOL. Given these findings, incorporating regular exercise into daily routines can be a powerful tool for enhancing overall health and longevity.
