Here's Why You Feel So Exhausted After a Vacation — and What You Can Do to Fix It

Before you leave for vacation, do the necessary prep at work to ensure a calm return. "Let people know you'll be out of the office and not to contact you unless it's a dire emergency," Dr. Jackson said. "Better yet, leave someone else in charge in your absence to take care of things." By preparing mentally and doing as much as you can on your to-do list beforehand, you'll give yourself a much smoother transition back into everyday life once the vacation is through.
