You can do a lot of things in 29 hours: work a part time job, watch 58 episodes of a sitcom, or listen to ‘Don’t Worry, Be Happy’ about 435 times. According to a study from Bar-Ilan University, working moms spend 29 hours a week worrying.

This study, picked up by Babble.com, demonstrates the “cycle of guilt” experienced by working moms who “feel they are being bad mothers for going to work and bad workers when they put their children first.” Trapped in this catch-22, worry results in less time, not to mention mental energy, for sleep, work, and childcare for working mothers.

Professor Shira Offer suggests that women bear a “double burden” of worry due to the tendency of women to change their work schedules to accommodate family issues. For example, mothers are more likely than fathers to take a day off of work to care for a sick child. That’s not to say men are worry free. Working men are reported to spend 24 hours a week worrying, losing a whole day.

Worry does more than just take up time; it can also contribute to lack of focus and a decrease in performance. If we didn’t spend so much time worrying, maybe we wouldn’t have as much to worry about.
