Nearly nine out of ten Britons wake up in a bad mood, but a sunny day and breakfast in bed can lift the blues, a new survey shows.
Those interviewed gave lack of sleep, oversleeping and the rush hour commute as the main reasons for morning grumpiness.
The survey was carried out for the Home-Grown Cereals Authority, organisers of Farmhouse Breakfast Week, which runs until Saturday.
More than half of those questioned - and 73% of 18-24-year-olds - said not getting enough sleep put them in a foul temper in the morning.
Three in ten blamed their bad moods on oversleeping, 25% their trip to work, 17% missing the bus or train, 17% thinking about work and 15% running out of milk or toast.
The survey said families with children were more likely to find mornings stressful, with women bearing the brunt of the strain.
More than a quarter of women said tidying up after everyone else put them in a bad mood, while 14% blamed their children's behaviour and 10% blamed their partner's behaviour.
By contrast men were less likely to blame their families for their early morning blues - but 27% said traffic jams put them in a foul temper.
Most likely to lift the spirits of Britons is the weather, with 29% of those interviewed saying a nice day would cheer them up.
A quarter said they felt better after listening to a favourite CD or radio station and 23% after having a cup of tea or breakfast in bed.
