In the US, from the ripe old age of about 5, children are trained to sit for ever increasing periods of time. By the time they are in middle school, it’s not an unreasonable expectation that students are expected to sit for about 45 minutes straight during class.
Fast forward to working a “desk job” after college and the number of hours we are expected to sit each week is staggering. Many folks through the 2020 work from home era were hard pressed to find opportunities between hour long meetings to take “bio breaks” to even meet their own needs with the restroom. Yes, I am definitely speaking from experience.
But a new study published in PLOS Medicine found a 9% increase in cancer death risk with each hour of prolonged sedentary behavior (aka. sitting). The good news is that they also found that movement has the opposite effect with each hour of interrupted sedentary behavior (defined as less than 30 minutes of sitting straight) saw a 19% reduction in cancer death risk.
As you might suspect, they also found that adding in activity reduced cancer death risk with a 12% benefit with an hour of light physical activity added into the day, an 8% benefit with 30 minutes of moderate activity added, and 22% benefit with 5 minutes of vigorous activity.
Sitting is the New Smoking
I know that we have well established the fact that “sitting is the new smoking”, but what have we done with that information as a society? What would work-life end up looking like if we actually took this study seriously and started to change our habits, starting with the youngest among us?
I’ve said before that even hamsters get wheels in their cages, but our children are definitely getting less fun in their school days than the common house pet. If we mandated that they were not to be sitting for more than 30 minutes stretches, how might we help teachers to implement such a shift? How would we adapt the job market to be ready for those children once they were ready to start working? Could we make a dramatic shift in the next 18 years?
I think we could. But we would have to rethink productivity and how we work. As someone who has been work from home for 6 years now and is self-employed for 3 years, I struggle to walk away from my desk.
Recently though, my body has had enough in the form of an injury from sitting. Well, most likely from driving while sitting, but it was not helped by the great deal of sitting I was doing when not driving either. It’s stopped me from being able to work the way I’m used to. Which has been frustrating and enlightening at the same time.
The Research and Life Collide
This injury has forced my hand. I can’t work for long stretches at my desk without getting up and moving around. Instead of suffering, I want to fully embrace this new schedule. This study, and the Apple News article that led me to it, are definitely helping to encourage me to keep working to find what works for me. Even if it isn’t what I would have done when working a corporate job.
But what about the rest of the folks that are dutifully sitting for hours at a time without getting up to move? Well, the results of the study would suggest that even just small adjustments in your work day could reap huge rewards. Breaking up sitting sessions (when possible) with a quick 5-minute walk to the water cooler or restroom and back would be a good start. If you work from home and are physically capable and can toss in just 5 minutes of vigorous activity into the middle of your biggest work blocks, you may even get the best ROI on your efforts.
Sad Corporate Reality
Corporations often expect long stretches of sedentary behavior, especially out of their more senior team members. But they are doing their employees a serious disservice that is reducing their mental capacity and work output. More is not always better.
Global corporate spending on wellness programs is set to top $94.6 billion this year (2026), and yet the research consistently shows that the results are not matching the investment. Well-being programs are failing, in part, because they focus on individual solutions rather than the broader systems that affect workers.
Fixing problems that come from structural issues isn’t something that individuals are going to be able to handle on their own during their lunchbreaks. And no amount of meal planning will get them out of it either. (Especially for busy families with youth athlete schedules – I talk more about that here).
But how many companies would be okay with someone getting up every 30 minutes, especially when children in middle school are trained ‘better than that’? Probably not many, unless we figured out a way to hold employers more accountable to their employees’ wellbeing.
What Change Might Look Like
Think it can’t be done? Japan has already done it through their Metabo Law, enacted in 2008. The Metabo law mandates annual health screenings and weight-loss counseling programs, creating a structure where the state, insurers, and corporations share accountability for employee health rather than leaving it entirely to the individual.
Instead of the victim blaming that we get in the US, Japan has written a social contract where the state is meant to provide educational resources and support for the wellness of its people. In order to do that, they need corporations to encourage their employees to adopt healthier lifestyles and make sure not to stand in the way of them participating in programs to do just that.
The accountability is financial. In Japan, companies face direct monetary penalties when employees are not getting the health support they need, shifting accountability from the individual to the institution. Individual workers can decline without facing any legal penalties, but companies cannot.
The best part of this law is that the data suggests that it’s working. A higher percentage of people participating in the support programs had reductions in obesity profiles at year three compared to non-participants. Participants also showed better reversal of metabolic syndrome.
Data like this support the idea that weight management is not just a personal moral issue. It’s a systemic one that needs community support to successfully tackle.
Fight for Your Right to Move
So many people I know have gone through the same transition from a more active work role in something like waiting tables, bartending, and retail through college to a desk job. And as their hours at the desk increased, so did their waistlines. That is no coincidence.
We know that obesity is linked to numerous types of cancers. So, it’s not surprising that one of the leading causes of obesity, sedentary behavior, is also linked to increased cancer death risk.
So here is the call to action. Everything is pointing to finding a reason to move more. But what if you did it in a way that was more fun than just moving for the sake of it?
Play might just be the ticket we all have been searching for and didn’t know it.
Play is something worth fighting for. Whether it’s the ability to play with your grandchildren or your desire to play another game of baseball, basketball, soccer, volleyball or any other sport, it’s way easier to stay motivated and moving so you can have more fun, right?
For me, this injury has been a forced experiment in doing what the research has been telling all of us to do for years. And honestly? I’m not mad about it anymore.
That is not to say that you don’t also need to find ways to break up long sitting sessions. Which I know is easier said than done. I’m a fellow traveler with you on this, on everything on this blog. But I believe that together we can push ourselves to make small changes that make a lasting impact on our wellbeing and help to keep our golden years looking cooler.
What’s the alternative? Never spend a dime of your retirement because you worked until the day you died? I’ve sadly seen that movie play out a couple of times already and I think I’ll choose a different path. I would love to have you along for that ride so we can get a little better at it every day. Together.
