Women have been found to wake their sleeping partners up at night because they are jealous of their partners nodding off within moments of hitting the pillow.
Sleep envy - as it is known - can turn a lovely lady into a less than likeable partner.
Figures show that 1 in 4 women admitted to deliberately waking up their partner because they are jealous they aren't able to fall asleep as easy.
The most common revenge is to simple toss and turn until their sleep-eyed partner wakes up.
The next wake up tactic is the 'accidental' poke or prod in the ribs.
Others used less than subtle tactics such as chatting until they got a reply, making a loud noise and even turning on the light or television.
One in ten actually confessed to pinching their partner to wake up.
The sleeping envy confessions came about after a poll was conducted about women and their sleeping habits. Around 25 per cent of the women took up to an hour to drop off, while most men said they fell asleep in under ten minutes.
A third of women said that they felt frustration at watching their partners effortlessly fall asleep while they toss and turn, leading to unnecessary arguments before bed.
"Not being able to sleep can be frustrating enough, bout our survey shows that it is made worse when you are next to someone who is sound asleep," the Daily Mail quoted for Silentnight, which carried out the poll, as saying.
"However this sleep envy phenomenon is actually doing more harm than good and will only prevent you from getting to sleep longer.
"Sleepless Brits should try tiring themselves out by reading or having a warm drink in another room, so as not to disturb their partners," he added.
