Feeling listless and sleepy on Monday? Well, the condition might be explained by the fact that Sunday happens to be the most sleepless night of the week.
The finding is based on a poll of 3,500 adults, commissioned by the hotel chain Travelodge, which found that nearly 60 per cent of workers sleep the worst on a Sunday.
A bad night's sleep certainly does have its repercussions, with one in four calling in sick at the start of the week, 46 percent being unable to concentrate at work, 30 percent showing an irritability towards their bosses and 20 percent dozing off at the desk.
And if Sunday is the day when you get your worst night's sleep, then Friday is the best, with eight in 10 people getting enough of time snoozing, reports the Telegraph.
16 million adults in the UK say that they suffer regularly from insomnia, with the majority blaming work related concerns for keeping them awake.
All that worry causes Brits to lose an average of 51 minutes of sleep each night. A figure that totals to a month's worth of sleep every year.
