People who were not active in their leisure time were almost twice as likely to have symptoms of depression compared to the most active individuals, the study found.

This finding is hardly surprising, but the researchers point out two particular tidbits that may be new:

Exercise during leisure time is the important part, not just physical activity in general.
The intensity of the exercise appears to be unrelated to its protective effects.

That means it's time to get up and get moving, even if it's just a little while for a little bit.
