Let it go: Reaction to stress more important than its frequency

A study by Penn State and Columbia University found that individuals who experience more negative emotions and perceive stressful events as more stressful have lower heart rate variability, a risk factor for cardiovascular disease. This suggests that reaction to stress is more important than its frequency in determining health risks.
