Sit me deadly

Standard

According to Owen, Bauman, and Brown

Research on physical activity and health has pointed clearly to increasing the time that adults spend doing moderate to vigorous intensity activities: 30 minutes a day is generally recommended. However, recent evidence underlines the importance of also focusing on sedentary behaviours—the high volumes of time that adults spend sitting in their remaining “non-exercise” waking hours. We provide a brief overview of recent evidence for the distinct relationships between ‘too much sitting’ and biomarkers of metabolic health and, thus, with increased risk of type 2 diabetes, cardiovascular disease and other prevalent chronic health problems. Particular concerns for this new field include the challenges of changing sedentary behaviours in the context of ubiquitous environmental and social drivers of sitting time; examining the effects of interventions for reducing or breaking-up sitting time and identifying the most relevant implications for clinical and public health practice.

According to Maria Cheng

While health officials have issued guidelines recommending minimum amounts of physical activity, they haven’t suggested people try to limit how much time they spend in a seated position.

“After four hours of sitting, the body starts to send harmful signals,” Ekblom-Bak said. She explained that genes regulating the amount of glucose and fat in the body start to shut down.

Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, independently of whether or not they exercised.

“People should keep exercising because that has a lot of benefits,” Ekblom-Bak said. “But when they’re in the office, they should try to interrupt sitting as often as possible,” she said. “Don’t just send your colleague an e-mail. Walk over and talk to him. Standing up.”

The last comment seems like from another century though. Yes, it would be convenient if all my colleagues were within walking distance, or even within driving distance, but it’s not going to happen. Plus it misses a main purpose of email, which is to communicate in a way that can be queued and does not interrupt concentration.
