Spending hours in front of a computer or TV screen could harm your heart.

Reports in the journal "Heart Asia" found that screen time results in poor heart health. Scientists did a series of treadmill test and determined that after those tests, participants who engaged in excessive screen time had a longer recovery period.

Scientists say compared to other sedentary behaviors, screen time expends even less energy than reading, writing or driving.
