Of course, regular vacations aren't as effective at keeping our hearts healthy as other important behavioral changes like stopping smoking, getting exercise, and keeping cholesterol levels in check.
But the finding was still impressive to the researchers behind the study.
"It shows how the body reacts to a lifestyle of stress," co-author Elaine Eaker told the New York Times.
Another study of rural women from Wisconsin in 2005 revealed that those who vacationed once every two years or less were more likely to be depressed and unhappy with their marriage than those who vacationed twice a year or more.
In general, the researchers found that the more time women spent without a vacation, the worse their stress levels were.
