Economist John Pencavel from Stanford says that calculation would vary by a bit for other professions, though.
"What neuroscience is showing is that we require down time in order for our bodies to go through the process of restoration," she told ABC News. "Without time and opportunity to do this, the neural connections that produce feelings of calm and peacefulness become weaker, making it actually more difficult to shift into less-stressed modes."
In fact, the mood-boosting effect of thinking about an upcoming trip has a more noticeable effect on your happiness than any post-vacation attitude shift, according to the same research.

A study funded by Air New Zealand in 2006 found that vacationers traveling from LA lowered their heart rates by around 4% after visiting New Zealand. People in the study also slept deeper and longer (around 20 additional minutes a night) when they returned to the US.
The effect on vacationers after the New Zealand study was measurable: "Reaction time was 30 to 40% higher than it had been before the trip," lead researcher Mark Rosekind told the New York Times in 2008.
"The only study that has ever come close to producing results this compelling was our NASA study testing the performance of airline pilots after taking a 26-minute nap," Rosekind said in a release.
Studies of middle-aged men with heart issues from around the world suggest they can be around 37% more likely to die from things like coronary heart disease if they go on vacation regularly, regardless of how much money they make.
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.
In 2017, researchers studied 38 people who went on a three month yoga and meditation retreat. They found the participants reported feeling less depressed and anxious, and their bodies showed changes, too.
Participants increased their plasma levels of brain derived neurotrophic factor protein (BDNF), which keeps nerve cells healthy, and saw reductions in markers of stress and inflammation in the body.
Even if you can't make time for a full-blown vacation, meditation has been shown to help relieve stress, ease feelings of depression, and boost your immune system.
Vacationers reported they were happiest when their trips excluded snaking lines or long, jet lag-inducing flights.
In a 2014 study published in the Academy of Management Journal, researchers examined 11 years of fashion-house trends and compared them to executives travel schedules. The results showed that more travel arguably made the couture better in the eyes of consumers.
Leadership experts Jack Zenger and Joseph Folkman published a comparison of vacation time and productivity around the world in the Harvard Business Review in 2015.
"Spending less time at your desk forces you to waste less time," they concluded.
Internal research from accounting firm EY (formerly Ernst & Young) suggests that the more vacation hours people take, the better their work reviews are, and the less likely they'll be to leave the company.
Cardio exercise has been shown to improve your mood, reduce risk of heart disease, and combat stress.
In 2012, researchers asked 13 desk workers to quit emailing for one week and hooked them up to wearable heart rate monitors.
They found that the participants' stress levels dropped and their focus improved. People found new ways to contact colleagues if they really needed them.
Katie Denis, who researches American vacation trends for the US Travel Association, recently called emailing on vacation "a quick way to ruin company culture" in the Harvard Business Review.
She said your colleagues will appreciate knowing that you trust that they will get things done and are organized enough to take a break.
