D
Whether in the office or at school, most people sit most of the day. For those hours of long-time sitting, there is now a healthy way to restore body and mind. According to a study published in Sports & Exercise in January, we can enjoy health benefits all round by walking for five minutes every half hour!
The research designed five exercise options for participants who sat for eight hours. The participants were asked to take a minute’s walk after 30 minutes’ sitting, take a minute’s walk after 60 minutes’ sitting, take a five-minute walk every half hour, or take a five-minute walk every hour. The last option is no walking at all. The researchers then compared the participants’ health.
They discovered that five minutes of walking every half hour was the only amount that showed decreases in blood pressure and blood sugar in significant amounts. Moreover, researchers observed improved moods. “The effects on mood and tiredness are important. People tend to repeat behaviors that make them feel good and that are enjoyable,” lead researcher Keith Diaz explained. As those feelings of getting up and moving around were positive, they could become a motivation for more routine walks during the day.
But sitting all day at work has become accepted. To change this, Diaz is trying to explain to employers that moving during the day is good on an individual level and also for the bottom line; a healthy worker is a more productive and satisfying employee.
When it comes to standing desks, he said, “I’m unsure whether there’s really strong scientific evidence that standing is really better than sitting. I worry people have this false sense that they’re healthy because they’re using this desk, and maybe they’re not actually that much better.”
If you’re sitting and haven’t walked around for a while, get up! Treat yourself to an exercise “snack” and then take another one in a half hour. The benefits of a simple, easy five-minute walk are obvious!
