Rethink the 10,000-a-day step goal; study suggests fewer steps are just as effective

Walking has always been touted as a great form of exercise, but just how many steps do we need to take each day to reap the health benefits? A recent study led by the University of Sydney suggests that walking 7,000 steps a day may offer similar health benefits to walking 10,000 steps, challenging the widely accepted notion that 10,000 steps is the gold standard for optimal health.

Published in The Lancet Public Health, the study analyzed data from 57 studies conducted in more than ten countries, including Australia, the U.S., the UK, and Japan. Led by Professor Melody Ding from the School of Public Health, the researchers examined the impact of different daily step counts on the risk of dying from cardiovascular disease and cancer, as well as the development of diseases such as cancer, type 2 diabetes, dementia, and depression.

The findings suggest that aiming for 7,000 steps a day is a more achievable goal for many people who may struggle to meet the traditional exercise guidelines. Professor Ding emphasizes that even small increases in daily step counts, such as going from 2,000 to 4,000 steps a day, can lead to significant health benefits.

The study looked at participants who wore step-counting devices, such as pedometers and fitness trackers, to track their daily step counts. Comparing health outcomes at different step counts, the researchers found that walking 7,000 steps a day reduced the risk of death by 47%, a benefit similar to walking 10,000 steps a day. Additionally, the risk of developing dementia dropped by 38% at 7,000 steps, with only a 7% extra reduction at 10,000 steps.

Other benefits included a 22% decrease in the risk of type 2 diabetes at 10,000 steps, with a further reduction to 27% at 12,000 steps. The study also found that significant health improvements were seen when people increased their daily steps from 2,000 to between 5,000 and 7,000 steps.

Dr. Katherine Owen, co-author of the study, notes that while 10,000 steps a day is beneficial for those who are already active, the extra benefits beyond 7,000 steps were modest for most health outcomes. The researchers are now working with the Australian government to use this evidence to inform future updates to physical activity guidelines.

In conclusion, the research suggests that focusing on progress rather than perfection is key when it comes to physical activity. Small increases in daily movement, such as aiming for 7,000 steps a day, can lead to meaningful health improvements. So, lace up your walking shoes and start stepping towards better health today.
