Americans are taking fewer vacation days now than they have in the last 40 years, according to a study published in the Harvard Business Review. Yet more and more data reveal that employees show greater success at work when they vacation more.

This is the premise of a new nonfiction book advocating for more vacations and family fun. "Top 10 Reasons Vacations Keep You Healthy" by David J. Nozar endorses a lifestyle that includes vacationing more. The book, billed as the "workaholic's cure for stress, debunks the destructive "all work and no play" mentality, providing information about vacations and how they play an integral part in health and wellness.

"If you are a business owner looking to increase your sales by 20 percent or more, your employees need to read this book and you need to make sure they take all their allotted vacation time," Nozar said. "All work and no play make Jack a dull boy. It can also make you tired, depressed and affect your physical health."

Top 10 Reasons Vacations Keep You Healthy dispels the common myth of hard continuous work leading to greater productivity, recommending time to break through this mindset to create greater health and happiness.

"It may seem simple, but studies have proved that getting away from it all can reduce stress, improve productivity and change your life for the better," Nozar said. "Not enough Americans take their designated vacations and this needs to change."

Previously an owner of a timeshare property, Nozar always felt there was a better option for families who wanted to vacation together and not break the bank. So he scoured the internet for the very best vacation club to market. During his in-depth search, the inspiration for Top 10 Reasons Vacations Keep You Healthy hit him full force. Through his research, he discovered that taking vacations can drastically improve one's overall health and well-being.

Nozar's short guide reveals the benefits of taking that much-needed vacation. The book is available at Amazon and Barnes and Noble in Kindle and Nook formats.
