People in the UK lost a bit of sleep over Brexit, their fitness trackers show

It appears people in the UK lost some shut-eye after casting their ballots for the EU referendum.

Sleep data from Jawbone showed its users in London slept, on average, 35 minutes less the evening of June 23, the night of the Brexit vote, than in the week before. Meanwhile, those in Dublin slept 15 fewer minutes. Data for the broader UK was not available.

With results not expected until “around breakfast time“ on June 24, it seemed many people also woke up earlier than usual.

In London, people wearing Jawbone’s tracker went to bed at 11:43pm, 11 minutes later than the week prior, and rose at 6:37am, 22 minutes earlier. Overall, they averaged 6.3 hours of sleep.

In Dublin, meanwhile, residents turned in at 11:50pm, seven minutes later, and woke at 7:08am, nine minutes earlier, averaging 6.8 hours of sleep.

All across the EU, people went to bed later and rose earlier, according to data for a subset of cities provided by Jawbone. There is, however, one curious exception: In Barcelona, which kicked off its Sant Joan festival that evening, people actually got eight extra minutes of sleep compared with the week before. Looks like they slept in: People in the city went to bed 59 minutes later and woke up 72 minutes later than usual.

Correction: A previous version of this article misstated the number of minutes Jawbone users in London woke up earlier by on June 24.
