After work, I sat down on the sofa, and my watch vibrated. It was a notification saying I had only walked a little over 4,000 steps today, far from my goal.

Honestly, I felt a bit annoyed at that moment. After a whole day of meetings and emails, it felt like I was being treated as a failure for not reaching 10,000 steps.

However, after reading a study that came out last summer, my perspective changed significantly. Today, I'll take my time to summarize that information.

First, we need to look at where the number 10,000 steps comes from. It wasn't derived from medical research.

In the lead-up to the 1964 Tokyo Olympics, there was a fitness boom in Japan, and in 1965, a company released a pedometer called the "manpo-kei," which literally means a device that measures 10,000 steps.

As the product's advertisement spread, the idea of 10,000 steps became a symbol of health. It's an easy-to-remember round number, which fitness apps later adopted as a default goal.

So, what does the actual data say? A meta-analysis published in The Lancet Public Health in July 2025 provides a pretty clear answer.

A research team led by Professor Melody Ding from the University of Sydney gathered studies published from 2014 to 2025. They reviewed a total of 57 studies and included 31 in the meta-analysis.

The important thing is that they only looked at studies that measured step counts using devices like pedometers, accelerometers, and fitness trackers, rather than relying on self-reported surveys. This makes the numbers much more reliable than what I might remember.

The comparison baseline was set at 2,000 steps. They examined how health indicators changed as step counts increased from this nearly sedentary level.

People who walked 7,000 steps had a 47% lower risk of all-cause mortality compared to those who walked only 2,000 steps. The risk of dementia was 38% lower, and the risk of death from cardiovascular disease was also 47% lower.

The risk of cancer mortality was 37% lower, depressive symptoms were 22% lower, and the risk of falls was 28% lower. The incidence of type 2 diabetes was found to be 14% lower as well.

I was genuinely surprised by these numbers. It's not even 10,000 steps, and yet there's such a significant difference at just 7,000 steps.

What's even more interesting is the shape of the graph. For metrics like mortality, dementia, and falls, the curve flattened out between about 5,000 and 7,000 steps.

In simple terms, the benefits gained from increasing the first few thousand steps are the greatest, and after that, the additional benefits from walking more diminish. The research team also explained that beyond 7,000 steps, there weren't significant additional benefits for most metrics.

That doesn't mean that 10,000 steps are useless. For conditions like cardiovascular disease, there are still benefits that continue to accumulate as step counts increase.

If you're currently around 2,000 steps, there's even better news. The research team noted that even increasing from 2,000 to 4,000 steps showed meaningful health benefits.

Similar results have been observed before. A study published in JAMA Internal Medicine in 2019 analyzed 16,741 women with an average age of 72 using accelerometers over a week.

In that study, women who walked about 4,400 steps per day had a lower risk of mortality compared to those who walked around 2,700 steps. While the risk decreased as step counts increased, it plateaued around 7,500 steps.

One thing I want to emphasize is that these studies are observational, so they don't prove a causal relationship that walking 7,000 steps directly reduces disease risk.

It's possible that healthier individuals tend to walk more. Therefore, I believe it's more appropriate to view these numbers as indicators that provide direction rather than guarantees.

It's also good to consider the CDC guidelines. Adults are recommended to engage in moderate-intensity aerobic exercise, like brisk walking, for 150 minutes a week, along with strength training on two or more days.

Those 150 minutes can be broken down into 30 minutes a day for five days, or even smaller increments. Sometimes, it's better to include some time walking at a pace that makes you slightly out of breath rather than just focusing on hitting step counts.

I'll share a method I've actually changed. I lowered my watch goal from 10,000 steps to 7,000 steps.

After lunch, I take a 15-minute walk around the neighborhood, and I intentionally park farther away from the entrance at the grocery store. I also take phone calls while standing and pacing.

Just by doing this, I find that I often reach 7,000 steps on weekdays more frequently than I expected. It's interesting how achieving my goals more often makes me want to walk even more.

However, if you have joint issues or chronic conditions like heart disease or diabetes, please consult with a doctor or pharmacist before suddenly increasing your step goals. Safe levels vary from person to person.

In conclusion, I've decided to stop feeling guilty about not hitting the 10,000-step mark. I believe that consistently walking 7,000 steps is much more realistic than occasionally hitting 10,000 steps and then taking several days off.

Even if my watch alerts me again today, I think I'll be less concerned about it. I encourage you all to start by adding just 2,000 more steps to your current count.
