People in the Midlands get the most shut eye in Britain - but one in 10 of us nationwide only gets less than four hours sleep, a new study reveals.
In central England, almost two-thirds of people (63%) believe they get a decent night's sleep overall - but one in 10 people in Wales said they only get between three to four hours of sleep a night on average.
In the South East of England, a similar amount (62%) are happy with the amount of shut eye they get on average.
That's in stark contrast to Northern Ireland which has the worst sleepers according to the data - with just over half (55%) revealing that they do not sleep well most nights.
The Midlands get the most amount of sleep
In Scotland one in two people said they usually have a bad night's sleep.
But people in the Midlands appear to have the most sleep, with one in 20 getting over 10 hours a night.
Sleeping arrangements vary from region to region and might affect the quality of sleep.

In the Republic of Ireland 49% of people admit to letting their pets in the bed.
And in Wales, sleeping next to a partner is the preferred sleeping arrangement, while a third of those in the North of England would much prefer to sleep alone.
The research of 2,000 adults by the Wool Room and Leeds University found that a third of Brits blame the hot weather for a lack of sleep at this time of year.
Changing the sheets regularly can help with a good night's sleep
Changing the sheets can also help with a better night's sleep, according to the research, which says 40% of Scots change theirs one a week.
The average amount people change their sheets is twice a month.
