Health Alert: Sitting less could add years to your life

(CBS) - Not sitting so much could boost your life expectancy. A study in the British Medical Journal found reducing the amount of time you sit to under three hours a day, could add two more years to your life. Researchers also found watching less than 2 hours of TV a day may add one year to your life. Previous studies have linked a sedentary lifestyle to increased health problems, including diabetes and heart disease.


(CBS) - There's more evidence out that how much you sleep impacts how much you weigh. Researchers in Germany and Sweden conducted sleep experiments. They found sleep deprivation increased how hungry patients felt and also raised the amount of the so-called "hunger hormone" in their blood. In addition, staying awake reduced the amount of energy the body used when resting -- meaning when we are sleep deprived, we burn off fewer calories.
