Sit less
Middle-aged women who sat for more than seven hours a day were 
47 percent more likely to show signs of depression than those who sat for four or fewer, Australian researchers found. Those who engaged in no physical activity were 26 percent more likely to have symptoms of depression three years later than those who met exercise guidelines. The research can’t prove that sitting makes you sad: It may be that people who are prone to depression are more likely to spend time sitting down. However, people who are more active may also be more likely to engage in social interactions with coworkers or neighbors. Plus, physical activity can release mood-boosting endorphins that fend off sad feelings.
