Here's how much of summer Britons have lost to hangovers this year

Hungover Britons lost 22 hours of their summer this year recovering from nights of heavy drinking, research has found.

While much of July and August has been a washout, the study found that boozing cost drinkers almost an entire day in the sun (or rain) over the past three months.

New figures released today by Cancer Research UK show that an average hangover lasted six and a half hours, while one in eight sufferers admitted their most recent one dragged on for more than 12 hours.

The survey of 2,000 drinkers also found that 24 per cent admitted the after-effects of their boozing stopped them going outside to enjoy good weather, rising to 40 per cent for 18- to 34-year-olds.

Close to 280,000 Britons have missed a flight due to a hangover, according to Office for National Statistics figures, and 23 per cent of young Britons admit they have missed a day out after a binge.

The charity is launching a second month-long alcohol-free “Dryathlon” challenge in September.

A study released last week found that downing water does not prevent hangovers.
