Researchers in Australia have found that even for those of us who exercise every day, spending the rest of the time sitting still is dangerous to health. As they put it, “Prolonged sitting is a risk factor for all-cause mortality, independent of physical activity.”
At the same time, a study in Finland used biosensors inserted into people’s clothing to see how much time they sat during the day. The scientists discovered that even exercisers spent about 70 percent of their waking hours sitting, an amount that threatens health.
