We all know that sitting for too long isn’t good for you. If you haven’t perfected your desk set-up and are hunched over your screen or slouched down in your chair it is even worse for you. However, a new study by Liverpool John Moores University revealed that we should be getting up and moving every half an hour.
The researchers discovered that sitting down for prolonged amounts of time can slow the blood flow around our body and to our brains. The study of a small group of men and women was split into three sessions to determine the best method for keeping the blood flow to the brain on an even keel. The first test was four hours of sitting and working at a computer screen, the second included a two and half minute walk on a treadmill every 30 minutes, the third session was an eight minute walk on a treadmill every two hours.
While taking an eight minute break every two hours did help increase blood flow to your brain, it wasn’t able to sustain it as well as taking a shorter break every half an hour.
The study didn’t look into the impact of low blood flow to your brain or whether it impacted productivity, but it did put more weight behind the theory that spending too much of your day sitting down isn’t good for you.
Previous studies have linked sitting too long with excessive weight gain, type 2 diabetes and other serious diseases. According to the NHS, many adults in the UK spend over seven hours sitting each day and as a result, it recommends we do at least 150 minutes of exercise each week. One study recently revealed that doing an hour of exercise each day could help ward off the effects of prolonged sitting.
If that feels you with dread, making small tweaks such as requesting a standing-desk at work, choose to stand rather than sit on the train et cetera. It goes without saying that swapping watching TV for playing tennis after work will also help improve your health. Whichever tweaks to choose to make, it’s definitely worth setting a reminder to get up more at work.
