Thinking of nixing your summer vacation because of a heavy workload or a demanding boss?

Most Americans lose an average of four vacation days per year, according to a survey conducted by the travel website Expedia. That means if all employed Americans forfeit four days, we’re wasting 500 million unused vacation days annually!

Why? Expedia says that most people cancel due to work concerns, some find it difficult to coordinate family schedules, while others prefer to cash out their unused days instead.

A summer getaway puts you in better moods — it’s a fact.

5. It reduces stress levels at work.

Tired of him constantly complaining about his tough boss? He needs a break. Evidence shows that leisure pursuits such as taking vacations alleviated job stress levels, in a study of 900 lawyers, conducted by Canadian researchers Joudrey and Wallace.

6. It strengthens family bonds.

The family that travels together, stays together.

“Family vacations contribute positively to family bonding, communication, and solidarity,” according to a study of international researchers led by Purdue University Xinran Lehto, which explored the positive impacts that vacations can have on families.

This is due to the time families spend together on vacation outside of their daily routines, making shared memories to last a lifetime.

7. It cultivates intimacy in your relationship.

According to research commissioned by the U.S. Travel Association, those couples who travel together are “significantly more satisfied with their relationships, enjoying better sex and improved romance long after the trip ends.”

In fact, the research found that taking even a weekend getaway was more likely to spark romance than giving small or large gifts. Lastly, we should note that not taking a vacation actually harms work productivity and the economy.
