In U.S., Exercise Has Bigger Emotional Payoff for Low-Income

Low-income Americans also reap more gains from healthy eating

WASHINGTON, D.C. -- Although all Americans report better emotional health when they exercise frequently and eat fruits and vegetables regularly, low-income Americans experience an even bigger emotional boost from practicing these good health habits than do those at higher income levels.

Mood Boost effect for Americans who Execise frequently and get fruits and vegetables daily, by income

These findings are based on 180,299 interviews with American adults conducted between Jan. 2 and July 8, 2012, as a part of the Gallup-Healthways Well-Being Index. The Emotional Health Index score is based on Americans' self-reports of positive and negative daily emotions, as well as self-reported clinical diagnoses of depression. Specifically, Americans are asked whether they felt or did "a lot of" each of the following the day before the survey: smiling/laughing, learning/doing something interesting, being treated with respect, enjoyment, happiness, worry, sadness, anger, and stress.

Low-income Americans experience greater improvement across almost all of the items in the Emotional Health Index when they exercise frequently and eat produce regularly than do those who are at a higher income level. For example, low-income adults who exercise three or more days per week are about seven percentage points more likely than their counterparts who exercise less than that to report experiencing happiness "a lot of the day yesterday." This compares to about a four-percentage-point increase for high-income adults who exercise frequently versus those who don't. Low-income Americans experience a bigger exercise "bonus" than do those with higher incomes in terms of daily smiling and laughter, enjoyment, and happiness.

Low-income Americans who exercise frequently also see a greater reduction in daily sadness and clinical diagnoses of depression than do those with higher incomes. However, Americans who exercise frequently at all income levels see an equal decrease is daily worry, and it is actually those making $90,000 or more per year who see the greatest stress reduction from routine exercise.

Percentage Point Difference in Emotional Health of frequent exercisers by income

Similarly, Americans in all income brackets who eat five or more servings of fruits and vegetables at least four days per week see widespread emotional health benefits, but it is particularly evident in those earning less than $36,000 per year. For example, low-income Americans who consume produce regularly are 3.9 points less likely to experience sadness "a lot of the day yesterday" than are their counterparts who don't. But, the reduction in sadness for high-income Americans who consume produce regularly is lower -- a decline of 1.9 points for those with annual incomes of $36,000 to $89,999 and -0.8 points for those making $90,000 or more per year.

Frequent exercise and healthy eating can help promote positive emotions and reduce stress levels. For low-income Americans these activities are particularly beneficial to their emotional state. They experience an increased emotional boost from exercising and healthy eating when compared to those with higher income levels, although even those who eat right and exercise routinely fail to match the emotional health of their more affluent counterparts.

It's possible that the mood-boosting side effects of exercise and healthy eating make more of a difference for those who experience more uncertainty in meeting basic needs every day. Low-income Americans also more generally report lower levels of positive emotions and higher levels of negative ones than do those with higher incomes, and thus have more room for improvement. Regardless, these results suggest that the ability to access safe places to exercise and affordable produce plays an important role in improving the emotional health of all Americans, particularly for the less wealthy.
