Is Sitting the New Smoking? Here's What the Science Actually Says

You've probably heard the line: sitting is the new smoking. It gets repeated so often it starts to feel like fact. But after 14 years teaching Pilates to people well into their 50s, 60s and beyond, I think it's worth asking: is it actually true?

Short answer: no. University of South Australia epidemiologist Dr Terry Boyle put it plainly: "Smoking is one of the greatest public health disasters of the past century. Sitting is not, and you can't really compare the two. Unlike smoking, sitting is neither an addiction nor a danger to others." Smoking raises your risk of dying early by around 180%. Sitting more than eight hours a day raises it by 10 to 20% — serious, but not in the same league.

Still, that doesn't mean sitting is harmless — especially as we get older.

Why movement matters more as you age

Our bodies were built to move. For most of human history, daily life meant walking, lifting, bending and reaching. It's only recently that so many of us spend hours a day sitting — at a desk, in the car, in front of a screen.

As we age, the cost of inactivity compounds. Muscle mass naturally declines after 50 (a process called sarcopenia), and long stretches of sitting speed it up. Weaker muscles mean a higher risk of falls, slower recovery from injury, and less independence down the track. Regular movement isn't just about how you feel today — it's about the life you want to be living at 70, 80 and beyond.

The research backs this up: just 2½ to 5 hours of moderate activity a week, plus muscle-strengthening work on at least two days a week (as recommended by the Australian Department of Health), makes a measurable difference to long-term health.

How Pilates helps

This is where Pilates earns its place. Strengthening your core and improving your posture directly counters the effects of a sedentary day — it's an approach I've spent 14 years refining with clients, as a Certificate IV Mat Instructor (Polestar Pilates Australia), a Pilates Association Australia (PAA) member, and someone who keeps learning through ongoing CPD.

Two things you can do right at your desk:

Neck stretch: Sitting or standing, tilt your head so your ear moves toward your shoulder. Rest your hand gently on top of your head and apply light pressure. Hold, then switch sides.

Shoulder rolls: Engage your core, then roll your shoulders slowly forward, up, back and down, five times. Reverse the direction and repeat.

The takeaway

Sitting isn't the new smoking. But staying still for most of your day, especially as you get older, is a habit worth breaking — for your strength, your balance and your independence.
