CNN —Sitting at your desk all day may put you at greater risk for heart disease –– even if you work out in your spare time, according to new research. This study was particularly helpful in investigating sitting because of its large sample size and the methodology it employed, Diaz said. “We would really recommend that as many people as possible avoid sitting more than 10.6 hours a day,” Ajufo said. The study is also observational, which means that while it can make associations, it can’t prove that the sitting was the cause of the heart disease, she added. To do their job well, muscles need movement.

CNN —As little as one or two minutes of vigorous exercise a day could lower your cancer risk, according to a new study. Participants reported not regularly exercising in their leisure time, and they wore accelerometers to track their VILPA, or vigorous intermittent lifestyle physical activity, the study said. Adults who incorporated about 4½ minutes of vigorous activity in short one- or two-minute bouts had more than 30% lower incidence rates of cancer, the study found. “The large majority of middle aged and older adults, more than 70-80% in most countries, are not regular exercisers in leisure time, or simply never do any exercise,” Stamatakis said via email. “Previous early-stage trials (showed) that VILPA leads to rapid improvements in cardiorespiratory fitness,” Stamatakis said in an email.

“If we don’t use them, things don’t work right.”When it comes to blood pressure, moving around helps improve circulation, Diaz said. Blood pressure and blood sugar were measured during each phase of the study. The strategy that worked best was five minutes of walking for every 30 minutes of sitting. All walking strategies resulted in a significant reduction of 4 to 5 blood pressure points, compared to sitting all eight hours. "When you do it without breaks, your blood pressure goes up and there are elevations in blood sugar.”Do standing desks help?
