Why does a season that's supposed to be about happiness and joy so often result in just the opposite? A survey by Consumer Reports found that 90 percent of Americans find at least one thing stressful about the holiday season (who are these 10 percent who feel no holiday stress?). Of course, it's possible that just having such expectations of the season to begin with, and then feeling the guilt at not meeting them, might be part of the problem. But whatever the reason, stress is what a lot of people will be unwrapping this year. Fortunately, much of it is returnable. So what follows are tips not only for holiday stress, but for the rest of the year as well. If you're in that 90 percent who's stressed out this week and next, this might be the list you should be checking twice. Your mind and body -- as well as your family -- will thank you.
