Study after study has [1]linked extended periods of sitting to cancer, diabetes, and heart disease. Unfortunately, even exercise doesn't offset the harm done by sitting. 'Now a consistent body of emerging research suggests it is entirely possible to meet current physical activity guidelines while still being incredibly sedentary, and that sitting increases your risk of death and disease, even if you are getting plenty of physical activity,' Travis Saunders, a Ph.D. student and certified exercise physiologist at the Healthy Active Living and Obesity Research Group at Children's Hospital of Eastern Ontario [2]told Runner's World. The common answer to the hazards of sitting is a standing desk, or even a treadmill desk, but not everyone can take advantage of those. Most people work in offices where they have little say over what kind of equipment they can use. Some people have health issues that prevent them from standing all day. Others, like yours truly, can't concentrate well while standing. Fortunately, research shows that frequent breaks every 20-30 minutes offsets the damage done by sitting. You could manually set a timer to remind you to stand up, but I've found a free solution to make it even easier: [3]Stand Up! by [4]Raised Square LLC. It runs on your iPhone, so you can use it at your home or office. Stand Up! does one thing and does it well. Open the app, select which days you would like alerts on, set a time range for those days, set an alert interval, and if you choose, even set alerts to work only at your current location. For a 99-cent in-app purchase, you can choose from a selection of alert sounds, though the free default is perfectly audible and pleasant. [5][tn_Stand-Up.jpg] By default, the app features a yellow theme, but if you wish, you can change it to a number of other colors. But not that it matters much; after setting your preferences in Stand Up!, you're done. Now, every few minutes (45 by default), you'll receive a notification on your iPhone telling you to stand up. [6][tn_Stand-Up-colors-notification.jpg] I've been using Stand Up! for a couple of weeks now, and I've noticed less pain in my back and posterior. There are a lot of apps out there that remind you to stand up, but Stand Up! is free, well-designed, and can be taken anywhere. In addition to that, it might extend your life. What else could you want?
