LATE nights make people crave a drink the next day, 研究显示.
It’s bad news for Brits with Christmas party hangovers.
Experts believe a tired brain may have less power to resist temptation.
And wanting to booze in working hours could be linked to combating stress and anxiety.
A team at the University of Washington, 我们, tracked 409 people aged 18 到 25.
They were quizzed for 70 days about their sleep habits and cravings for alcohol and cannabis — which is legal in the state.
Participants slept eight hours on average. Many had no desire to drink in the day — unless tired.
Study author Dr Scott Graupensperger told journal Addictive Behaviours: “Stronger craving was reported on mornings and afternoons after shorter sleep duration.”
A third of British men and one in seven women drink unhealthy amounts of booze.
The NHS suggests 14 units a week — six pints of beer or six medium wines.
The World Health Organisation previously found those working 49 or more hours a week guzzle an extra pint or glass of wine, compared to those doing nine-to-five.
