If it seemed as if Washington-area residents were stumbling around like the walking dead the day after last week’s presidential election, it may be because they stayed up late waiting for results and awoke early the next day.

According to the folks at Fitbit Inc., the maker of the wrist-worn, wireless fitness trackers, residents of the nation’s capital lost more sleep the night of Nov. 8 than people elsewhere in the country. D.C. residents who wore Fitbits logged 49.75 fewer minutes of shut-eye than on a typical night — far above the national average of 29.62 minutes of lost sleep.

Fitbit said Monday that researchers reviewed a sampling of its 10 million users across the nation to see how sleep patterns were affected by the wait to see whether Republican Donald Trump or Democrat Hillary Clinton would emerge as the nation’s 45th president.

What the Fitbit could not tell was whether anxiety, excitement or other emotions played into the sleeplessness. The devices track movement to tell whether a user is slumbering.

“Was it excitement, stress? That’s not known, but we were surprised and impressed to see such a change in sleep in a typical day,” said Karla Gleichauf, Fitbit research data analyst.

In addition, Virginia and Maryland ranked among the top 10 sleep-deprived states.

Virginia residents came in fourth with about 40.03 minutes of lost sleep, and Maryland residents came in 10th with 36.93 minutes. Other East Coast states, including New York, Florida and Massachusetts, were in the top 10. Alabama and Arkansas also made the list.

Researchers at the San Francisco-based company said this presidential election night marked the greatest sleep-loss numbers since it began tracking patterns in 2009, two years after the company was founded. The second-biggest loss of sleep for users was the night of Super Bowl 50 in January, when average users lost about eight minutes of sleep.

Fitbits measure data such as the number of steps walked, heart rate and the number of stairs climbed to help the user monitor health and weight.

The devices also measure sleep patterns. They can even tell when the user awakens briefly during the night but doesn’t realize it.

Manassas, Va., resident Lorrie Grant has owned her Fitbit since July, when her older brother gave it to her as a birthday gift.

Grant said she did not go to bed on Nov. 9 until about 2 a.m., about two hours after her normal bedtime. She woke up about 8 a.m., nearly an hour later than normal, and had to rush out to a 10:30 a.m. work meeting as managing editor for Transport Topics, a weekly publication about the freight­ ­industry.

“I was lethargic and sluggish,” the 53-year-old said. “I just attributed my mood to Trump winning. But I didn’t have enough rest.”

Anthony Lorenzo Green, 30, of the District, does not own a Fitbit. But on the morning after the election, he had to request two hours of personal leave so he could come in late after saying up until 5 a.m.

“I didn’t expect to stay up that late. I was just sitting in shock for a while. I kept thinking something was missing. I was afraid to go to sleep on bad news,” the D.C. Department of Employment Services employee said. “That next day, everyone was walking around like it was a funeral. I thought it was just the results of the elections. But it was probably lack of sleep as well.”
