Jawbone data finds UK residents lost some sleep during the vote for the country to leave the European Union, according to Quartz.

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, 35 minutes earlier. Overall, they averaged 6.3 hours of sleep.
