Can Exercise Make You Happy? Or Does Happiness Help You Exercise?

Whether and how exercise fuels happiness has been the subject of much research with few solid conclusions. But the evidence is getting much stronger, as more and more findings tie physical activity to happiness, even if they often leave open the question of which causes which.

The case is bolstered by a new study that provides some of the strongest objective evidence yet that exercise can thwart depression—arguably the inverse of happiness, or at least an obstacle on the road to mental wellbeing.

Importantly, it doesn’t seem to take much time to improve your mood, if the exercise-causes-happiness claims are directionally correct. Taking the stairs at work, sweeping out the garage or tending to your garden, in combination with other physical activity, appears to sow some seeds of happiness, a recent review of nearly two dozen studies found.

“The link between exercise and mood is pretty strong,” says Michael Otto, a professor of psychology at Boston University, speaking to the broad body of research. “Usually within five minutes after moderate exercise you get a mood-enhancement effect.”
