When’s the last time you went on vacation? If you’re a millennial, there’s a good chance it’s been a while.

According to Expedia’s recently released 2017 Vacation Deprivation report, millennials are the most vacation-deprived age group in the U.S. The report, which examines the vacation habits of more than 30,000 working adults across 30 counties, reveals not only that millennials are less likely to take time off than older workers, but that they also receive less vacation time and are more likely to take shorter trips due to impending workloads.

But millennials aren’t the only ones who fail at striking a work-life balance. The report states around half of all U.S. workers said they feel “somewhat or very vacation deprived,” despite the fact that nearly all Americans recognize the benefits of taking time off. According to the report, Americans said they return from vacations feeling happier (96 percent), better rested (93 percent), less stressed (94 percent), in better health (93 percent), and closer to their partner or family (90 percent).

The report also noted some of the professional benefits that come with taking time off, including improved attitude, higher productivity, and feeling more relaxed at work.

“This study confirms what we already know — that taking time off is a critical piece of living a happy, balanced life,” said Nisreene Atassi, global head of communications for Expedia.com. “If the thought of taking a week or more off work is causing you to put vacation plans on hold, consider taking a long weekend or adding personal time onto a business trip. Even a short refresh can be a game changer for your mental and emotional health and wellbeing.”

Even though vacation deprivation levels are on the rise worldwide (53 percent up from 49 percent in 2016), the report did reveal that American attitudes around time off and vacations are shifting. According to the report, Americans this year reported a reduced vacation deprivation level, down four percent from 2016. Furthermore, Americans also said they feel less guilty about taking time off than they did one year ago. Despite this, however, the number of vacation days used and lost by the U.S. workforce remains the same, with most Americans using fewer vacation days than they receive.
