How people get it: Free. Standing up and moving more often during the day.
The basics
What it is
One study team said sitting too much is not the same as lack of exercise and has its own effects on the body.
How people are exposed, and how it may affect health
Sitting is thought to affect the body differently from lack of exercise, including lower enzyme activity in leg muscles. Standing and brief sit-to-stand moves use little energy but are thought to engage muscles and improve blood flow.

What the research has found so far
Researchers said people who exercise but still sit for hours may have higher risk than expected, though findings are mixed. Standing-focused programs have been shown to cut sitting by up to two hours a day.

On too much sitting and aging, PubMed lists 672 trials in people, 3,196 studies that watched people over time, 31 animal and lab studies. See the counts and searches
Stage 4 because it is recommended in the US Physical Activity Guidelines for Americans (adults should move more and sit less throughout the day). See the source ↗

Side effects and risks
The WHO says higher amounts of sedentary behaviour, such as sitting, are linked to poor health outcomes in adults, including higher death rates from all causes.
Who may be more affected
Pages say that in children and teens, more sitting is linked to more body fat, poorer heart and metabolic health, poorer fitness and behaviour, and less sleep.
Questions to ask your doctor
- Is my exposure to too much sitting something to think about, given my health?
- Is there a test that measures it, and would it tell us anything useful?
- Which ways of lowering exposure are worth the effort, and which aren't?
- Is anything in my home, work or diet likely to be a big source?
This is general information gathered from the sources listed, not medical advice. Talk to your doctor before starting anything new.

Too much sitting hurts even young, active people ↗
“Lengthy sitting sessions can raise even a younger adult’s BMI nearly a full point compared to people who sit only a few hours out of the average day.”
Prolonged sitting raises heart disease and obesity risks in young, active adults, and current exercise guidelines may not offset the harm.
Too much sitting hurts the heart ↗
“A new study shows that being sedentary increases the risk of the most common types of heart disease, even among those who get enough exercise.”
A Mass General Brigham study found that sedentary behavior raises heart disease risk, even in people who exercise enough.
Your standing desk isn’t making you any healthier ↗
“Sitting for long hours is bad for our health. Standing up may not be much better, though.”
A large study found standing over two hours a day does not protect against the cardiovascular risks of too much sitting.
