A new study found that doing a variety of physical activities can help you live longer. The researchers looked at data from two large studies and found that people who did different types of exercise had a lower risk of death.

This one change to your exercise routine could add years to your life. Regularly engaging in a variety of physical activities can be one of the most effective ways to extend lifespan, according to research published in the open access journal BMJ Medicine.

The findings suggest that the relationship is not simply about doing more exercise. Instead, benefits appear to level off after a certain point, indicating there may be an optimal amount of activity.

Researchers analyzed data from two major long-term studies: the Nurses' Health Study (121,700 female participants) and the Health Professionals Follow-Up Study (51,529 male participants). These studies tracked participants for more than 30 years, with regular updates on lifestyle, health history, and exercise habits collected every 2 years through questionnaires.

Participants reported a wide range of physical activities over time. Since 1986, this included walking, jogging, running, cycling (including stationary machines), lap swimming, rowing or callisthenics, tennis and squash or racquetball. Later surveys added more detail, covering weight training or resistance exercise; lower intensity exercise, such as yoga, stretching, and toning; vigorous tasks like lawn mowing; moderate outdoor work such as maintenance and gardening; and heavy outdoor work like digging and chopping.

The analysis included 111,467 participants for total physical activity and 111,373 participants for activity variety. To measure activity levels, researchers used MET scores, calculated by multiplying the average time spent on each activity (in hours/week) by its MET value. METs indicate how much more energy an activity uses compared to resting.

Higher levels of physical activity, along with most individual types of exercise except swimming, were linked to a lower risk of death from any cause. However, the relationship was not linear. The benefits of total activity appeared to level off after about 20 weekly MET hours, suggesting there may be a point beyond which additional activity provides less added benefit.

Walking showed one of the strongest associations, with those who walked the most having a 17% lower risk of death compared with those who walked the least. Climbing stairs was linked to a 10% lower risk. Other activities were also associated with reduced risk when comparing the least active to the most active participants.

The researchers emphasize that staying active overall remains important. Habitual engagement in most types of physical activity was associated with lower mortality. The variety of physical activity was inversely associated with mortality, independent of total physical activity levels.

Overall, these data support the notion that long term engagement in multiple types of physical activity may help extend the lifespan.

Why It Matters

As Indian students prepare for competitive exams and life beyond school, it's essential to prioritize their physical health. This study shows that exercising regularly and trying different activities can have a significant impact on longevity.
