The Dangers of Physical Inactivity to our health – The lancet
What if the simplest path to better health, longer life, and more joy wasn’t a supplement, diet, or program — but simply moving your body a little more each day?
A landmark 2012 study published in The Lancet — one of the world’s most respected medical journals — sought to answer a powerful question:
How much disease, death, and loss of life expectancy is caused by physical inactivity worldwide?
The findings are staggering. But they also offer hope.

I’ve created a new video unpacking the key takeaways from this global study — and how we can shift our habits in a way that feels aligned, joyful, and sustainable.

In this post, I want to share the core insights from the research — and why this matters so deeply for anyone committed to long-term vitality.
The Study:
“Effect of Physical Inactivity on Major Non-Communicable Diseases Worldwide: An Analysis of Burden of Disease and Life Expectancy”
Published in The Lancet, Volume 380, Issue 9838, Pages 219–229, July 21, 2012
By I-Min Lee et al.

This global meta-analysis reviewed population data from around the world to estimate how many cases of major chronic diseases could be attributed to physical inactivity — and what could be gained if we moved more.
Specific Health Impacts of Physical Inactivity
According to the study:
- 6% of all coronary heart disease (CHD) cases are linked to inactivity
- 7% of all type 2 diabetes cases
- 10% of breast cancer cases
- 10% of colon cancer cases
- 9% of all premature deaths globally — equivalent to over 5.3 million deaths per year
This makes physical inactivity one of the most significant — and most overlooked — preventable causes of death worldwide.
What Happens If We Reduce Inactivity?
The study also explored the potential benefit of even modest reductions in inactivity:
- A 10% reduction in inactivity could prevent over 533,000 deaths per year
- A 25% reduction could prevent over 1.3 million deaths annually
- Eliminating inactivity altogether could increase global life expectancy by 0.68 years
(with variations between 0.41 and 0.95 years, depending on region)
Why This Matters — And Why It’s Not Just About Fitness
These numbers aren’t just statistics — they represent real people, real lives, and a global health challenge that affects us all.
But here’s what’s often missed in the conversation:
This isn’t about gyms, six-packs, or routines. It’s about moving through daily life with energy and presence. About walking, playing, lifting, climbing, dancing, sweeping, gardening — whatever helps your body live like it was meant to.
This is about reclaiming our natural rhythm of movement — in ways that are joyful, human, and doable.
My Take: Movement as Medicine, But Also as Joy
In the video, I share why this message has guided so much of my own work — and how I’ve personally re-imagined what healthy living can look like. Not punishment. Not restriction. But rhythm, play, and connection.
We’ve created a world of comfort. But we’ve traded in something essential.
It’s time to bring that back.
