According to a study published in the journal Circulation, the risk of cardiovascular disease (CVD) in older people can be greatly decreased by walking 6,000 to 9,000 steps per day. The study revealed that the risk of CVD, including heart attack and stroke, is reduced by 40 to 50%.

In the study, the researchers analyzed the data collected from 20,000 people in the US and 42 other countries. The average age of the study participants was 63.2 years, plus or minus 12.4 years, out of which 52% of the participants were women.

The findings of the study showed that with every additional 1,000 steps, the risk of CVD was reduced exponentially. They also saw a progressive reduction in CVD risk for people who walked up to 15,000 steps per day. However, the study also showed that there was no association between increasing one′s steps and lowering CVD risk for younger adults.

Additionally, the researchers suggested that people who want to reduce their risk of CVD should set goals that feel more attainable rather than setting goals, which is not based on scientific research.
