How Often Should You Get Up from Sitting? Every Hour or Every 30 Minutes

How long should you sit at a time before getting up?

The Dietary Guidelines for Chinese Residents (2022) recommend getting up to move every hour. The American Diabetes Association recommends that people who have diabetes or are at risk for it break up sitting at least every 30 minutes.

What each organization says:

Dietary Guidelines for Chinese Residents (2022): cut down on sitting, and get up and move every hour.^[1]
World Health Organization guidelines, 2020: “Adults should limit the amount of time spent being sedentary.”^[2]
The American Diabetes Association (ADA), in its Standards of Care in Diabetes—2026, recommends that people who have diabetes or are at risk for it break up sitting at least every 30 minutes, for benefits that include blood sugar control.^[3]

Getting up from sitting every hour vs. every 30 minutes: what’s the difference?

“Every hour” is everyday advice for all adults; “every 30 minutes” comes from the American Diabetes Association’s advice on blood sugar and from a study that tracked risk of death.

In one study, 7,985 Americans aged 45 and older wore sensors that recorded their activity and were followed for about 4 years. People in the quarter with the longest average sitting bouts were about twice as likely to die as those in the quarter with the shortest; the larger the share of sitting time spent in bouts under 30 minutes, the smaller the added risk. Based on this, the authors suggest that getting up every 30 minutes may be a reasonable goal.^[4]
In a study of 4,757 U.S. adults, the quarter who got up from sitting most often had waists 4.1 cm (1.6 inches) smaller on average than the quarter who got up least often (95.1 cm against 99.2 cm). In this study, even 1 minute of activity counted as a break, and participants took about 92 breaks a day on average.^[5]
An analysis pooling 37 studies found that breaking up sitting with activity lowered after-meal blood sugar, insulin, and triglycerides compared with sitting the whole time; people with a higher body mass index saw bigger drops in blood sugar.^[6]

The two numbers don’t conflict: if you get up every 30 minutes, you’re also getting up every hour.

If you use Apple Watch, you can’t set its stand reminder to every 30 minutes; for the built-in workarounds, see Can You Set the Apple Watch Stand Reminder to Every 30 Minutes? How to Get a Reminder Every Half Hour. If you want a reminder only after you’ve sat for a time you set, consider MoveMonkey, a stand-up reminder app: it counts from when you last got up and reminds you only after you’ve sat for the 30, 45, 60, or 90 minutes you set.

Why does sitting affect blood sugar, and how does getting up to walk help?

When a muscle contracts, it takes glucose out of the blood, without needing help from insulin; while you sit, the big muscles in your legs do almost no work.

A joint position statement from the American College of Sports Medicine and the American Diabetes Association: when muscles contract, they move glucose from the blood into the muscle through a pathway independent of insulin, and neither insulin resistance nor type 2 diabetes impairs this pathway.^[7]
Skeletal muscle is where most glucose goes after a meal: under lab conditions that keep insulin high, skeletal muscle takes up about 80% of the glucose.^[8]
One study measured 84 adults: during 30 minutes of sitting, their thigh muscles were inactive about 90% of the time.^[9] In another study, thigh muscle activity while standing was about 2.5 times that while sitting.^[10]
In energy use, measured in METs (sitting quietly = 1): sitting quietly is 1.0, standing quietly is 1.3, and walking slowly (2.0–2.4 mph, or 3.2–3.9 km/h) is 2.8.^[11]

What counts as sedentary behavior?

The World Health Organization’s definition: “Any waking behaviour characterised by an energy expenditure of 1.5 METs or lower while sitting, reclining or lying.” Most desk-based office work, driving, and watching TV count as sedentary behavior.^[2]

How long should you walk after sitting? Is standing up enough?

In an experiment, walking slowly for 2 minutes every 20 minutes lowered after-meal blood sugar by about a quarter; getting up to walk works better than just standing.

In one experiment, 19 adults aged 45 to 65 who were overweight or obese got up after every 20 minutes of sitting and walked slowly at 3.2 km/h (2 mph) for 2 minutes. Over the 5 hours after a test drink containing glucose and fat, their blood sugar rose 24% less than when they sat the whole time, and their insulin 23% less; walking briskly instead made no clear difference compared with walking slowly.^[12]
An analysis pooling 7 experiments found that, compared with sitting the whole time, getting up to walk slowly lowered after-meal blood sugar by about 17% on average, and just standing up by about 9.5%.^[13]

How many hours of sitting a day is too much?

Canada’s guidelines recommend sitting no more than 8 hours a day.

Canada’s 2020 guidelines for adults: limit sitting to 8 hours a day or less, including no more than 3 hours of screen time in your free time, and break up long periods of sitting as often as you can.^[14]
