NBA players perform worse after late-night twitter use, study finds

STONY BROOK, N.Y. — Twitter has long been a popular soapbox for professional athletes to speak their minds or simply converse with fans, but could it damaging to their careers? A new study finds that late-night tweeting causes NBA players to perform worse on the court the next day.

Researchers at Stony Brook University examined 112 NBA players’ Twitter accounts from 2009 through 2016 and then analyzed their game-by-game statistics using Yahoo Sports. The authors specifically looked for tweets posted between 11 p.m. and 7 a.m. Statistics were only utilized for the study when a game occurred within the time zone that corresponds to where the player lives.

A new study finds that NBA players perform worse during games if they were up late the night before posting on Twitter.

After examining the 30,000 tweets among the players, the researches determined that when players tweeted late at night, their shooting accuracy dropped by about 1.7 percent in games the next day and they averaged about 1 point less. They also took fewer shots, and recorded fewer rebounds, steals, and blocks.

The researchers point to sleep deprivation as a primary consequence of late-night tweeting, which can impact a player’s performance.

“Using late-night tweeting activity as a proxy for being up late, we interpret these data to show that basketball skills are impaired after getting less sleep,” says lead researcher  Dr. Jason J. Jones, an assistant professor of sociology, in a press release by the American Academy of Sleep Medicine. “While experimental studies have shown the impact of sleep deprivation on performance, this study uses big data to provide interpretable results on real-world performance of basketball players.”

Players who tweeted after hours also averaged about 2 minutes of less playing time in the following game, a serious result that could have an interesting impact on team or even league rules regarding the use of social media — especially during playoffs. The researchers believe the most important takeaway is that less sleep means less productivity, no matter what your career.

“Our findings are relevant beyond just sports science research,” says study co-author Dr. Lauren Hale, Professor of Family, Population and Preventive Medicine in the Program in Public Health at Stony Brook. “Our results demonstrate a broader phenomenon: to perform at your personal best, you should get a full night of sleep.”

The study’s findings are being presented today at SLEEP 2017, the 31st Annual Meeting of the Associated Professional Sleep Societies, in Boston.


  1. It’s a good thing Twitter wasn’t a thing while Shaq was in his early days. If his free throw percentage dropped by a percentage point he’d statistically be more likely to make it in the wrong basket.

  2. That’s because if they aren’t tweeting they’re doing boom boom getting the poison out so they can focus on the game the next day.

  3. With an average IQ of 70, it takes all of a black man’s strength to get those two word tweets out.

    1. How is it that you conservatives try to claim that you’re not racist, but then you go and say stuff like this?

      1. Fact; 1 in 3 black males will be incarcerated. That means locked up in jail. Go check Virginia. Terry mcaulfluff admitted that a large % of his blacks were in jail.. Isn’t that wonderful?

      2. It’s not a question of Conservatism. Sadly, it is a matter of fact, though the actual number is closer to 85. Look around the world. There are always exceptions but who has succeeded and who has failed in the collective sense?

        Europe has a problem with Muslims “assimilating.” After 300 years, the US has an unfortunately similar issue that, of course, can never be discussed in polite (politically correct) society.

        FBI stats:

        Black males between 16 and 36, though only 2 to 3 percent of the population, are responsible for a third of all our crimes. (Hey, that’s ONE-THIRD of all crimes. Got that? One-third of ALL crimes. ALL crimes. Yes, ALL CRIMES.)

        The black crime rate is seven times as high as the white rate. It is a country where white criminals choose black victims in 3 percent of their crimes, but black criminals choose white victims in 45 percent of their crimes.

        Here is a sad insight from a well respected black pastor:

        I don’t know what the solution is. Maybe we really weren’t meant to “all just get along.” 🙁

  4. Yeah, there’s something I care about: Grossly overpaid leaping mutant illiterates not getting enough sleep.
