One survey by the American Psychological Association uncovered some interesting data about the holiday blues:While the majority of people in the survey reported feelings of happiness, love, and high spirits over the holidays, those emotions were often accompanied by feelings of fatigue, stress, irritability, bloating, and sadness.Thirty-eight percent of people surveyed said their stress level increased during the holiday season. Participants listed the top stressors: lack of time, lack of money, commercialism, the pressures of gift-giving, and family gatherings.Surprisingly, 56 percent of respondents reported they experienced the most amount of stress at work. Only 29 percent experienced greater amounts of stress at home.
