A new international study has found that walking just 7,000 steps a day may significantly lower the risk of serious health conditions, including heart disease, type 2 diabetes, and dementia — challenging the long-held belief that 10,000 steps per day is necessary for optimal health.
Published in The Lancet Public Health, the research analyzed data from over 160,000 participants across 31 global studies and concluded that 7,000 steps may be the “magic number” to improve health outcomes. Researchers found a 38% reduction in dementia risk, a 28% decrease in falls, and a 6% drop in cancer risk among individuals reaching this daily step threshold.
“These findings debunk the myth that 10,000 steps per day is required for good health,” said Dr. Daniel Bailey, a sedentary behaviour and health expert at Brunel University London, who was not involved in the study. “The real-world implication is that even small increases in daily movement — such as 1,000 extra steps — can lead to measurable health benefits.”
While prior studies have linked walking to improved cardiovascular health, this is the first major review to assess its effects across a broad range of conditions. Researchers noted that even people who walked as few as 4,000 steps a day showed better outcomes compared to those with very low activity levels, such as 2,000 steps or less.
The health benefits, however, appeared to plateau at around 7,000 steps for many outcomes — suggesting that pushing toward 10,000 may not be necessary for most people.
Though the study shows promising associations, researchers acknowledged some limitations. Data on cancer and dementia outcomes came from a smaller number of studies, and not all research included in the analysis accounted for key variables such as age and frailty.
Experts continue to stress that while step count is important, exercise intensity also matters. Health guidelines recommend adults engage in at least 150 minutes of moderate activity or 75 minutes of vigorous activity per week.
Still, the findings offer encouragement for those struggling to meet traditional fitness targets. “This study adds to the growing evidence that physical activity — in any amount — is vital for our physical and mental health,” said Professor Steven Harridge of King’s College London.
In a world increasingly shaped by sedentary lifestyles, researchers say the message is clear: even modest movement can make a meaningful difference.
