For healthy aging, light exercise or sleep beats being sedentary

If you want to increase your odds of living a long and healthy life, watch less television and become more physically active, because even a small amount of physical activity can improve overall health, according to an observational study published last month in JAMA Network Open.

While there have been many studies showing that moderate to vigorous physical activity is associated with healthy aging, researchers wanted to know if light physical activity compared with sedentary behaviors also improves healthy aging, and if not, how can people’s time be reallocated.
