Is exercise the elixir of youth? It may lower risk of early death by up to 40%, new study finds
Context:
Engaging in regular exercise that elevates heart and breathing rates can significantly reduce the risk of early death by up to 40%, as revealed by a comprehensive meta-analysis of 85 studies involving 7 million people globally. The positive effects of physical activity on longevity are more pronounced in older adults, who can reduce their risk of death by an additional 10% to 15% when they become active, even later in life. While adhering to the World Health Organization's exercise guidelines maximizes benefits, even moderate activity levels can substantially lower mortality risks compared to inactivity. The study emphasizes that the benefits of past physical activity may diminish if individuals cease exercising, highlighting the importance of sustained physical engagement. Exercise not only decreases risks of cardiovascular diseases and cancer but also enhances overall well-being, with recommendations to incorporate resistance training for added health benefits.
Dive Deeper:
A meta-analysis of 85 studies involving 7 million people indicates that regular exercise can reduce the risk of early death by up to 40%, highlighting the critical role of physical activity in promoting longevity.
The research found that older adults benefit significantly from increased physical activity, with potential risk reductions of 10% to 15% due to their higher likelihood of facing multiple health challenges.
Meeting the World Health Organization's exercise guidelines can maximize health benefits, though even minimal activity is beneficial compared to a sedentary lifestyle, with a 22% decrease in early death risk for new exercisers.
Consistent physical activity is necessary to maintain longevity benefits, as those who stop exercising face similar early death risks as those who are consistently inactive.
Exercise is particularly effective in reducing the risk of heart disease and cancer, with the greatest increases in lifespan observed when individuals engage in at least 300 minutes of moderate exercise weekly.
Incorporating resistance into workouts, such as using weights or swimming with fins, can enhance the benefits of aerobic exercises by combining cardiovascular and strength training.
The study underscores the importance of personalized exercise routines, suggesting that matching physical activities to personal preferences and capabilities can improve adherence and health outcomes.
