Even the “King of All Media” needs to unplug sometimes.

Howard Stern shocked his fans by unexpectedly canceling his show and taking a personal day on Wednesday, which long-time listeners claimed the SiriusXM host has never done before.

Concerned fans fretted on social media that marital troubles, sick parents or Stern’s own health were behind the 63-year-old shock jock’s sudden absence.

While no one from “The Howard Stern Show” has offered an explanation yet, the truth is that personal reasons exist for just that: personal reasons.

The average American gets three paid personal leave days a year, or flexible paid time off (PTO) when sudden needs arise that don’t call for a sick day, but that you also wouldn’t want to waste a vacation day on. These include taking care of a sick child or attending a parent-teacher conference, going to a doctor’s appointment, voting or observing a religious holiday.

These can also be used as mental health days to invest in a little self-care, like catching up on sleep, going for a walk, meditating, or spending extra time with your family. Studies show that people who take time off to decompress return to work more productive. And paid personal leave increased 20% between 1992-1993 and 2012, according to the Bureau of Labor Statistics, so that more than a third of U.S. workers have access to personal days.

Too bad we don’t take them. There’s still a stigma attached to taking care of ourselves, which is why more than half of us don’t use all of our paid time off. A CareerBuilder.com survey revealed that employees uncomfortable with officially taking a mental health day have called in sick to make their own personal days, with 27% of people taking the day for a doctor’s appointment, 18% catching up on sleep and 11% running personal errands.

Stern is expected to return Monday, so stay tuned.
