A study has found a direct relationship between how much sleep a person gets and their level of desire the next day, the amount of shut-eye also affects how aroused they will become.
The study, involving 171 women, showed that each additional hour of sleep increased the likelihood of sexual activity with a partner by 14 per cent.
Sleep was also important for genital arousal, according to the research, published in the Journal of Sexual Medicine.
Specifically, women who slept longer experienced fewer problems with vaginal arousal than those who obtained less sleep.
'The influence of sleep on sexual desire and arousal has received little attention in the field,' said Dr David Kalmbach, of the University of Michigan, but these findings indicate that insufficient sleep can decrease sexual desire and arousal for women.'
He added: 'I think the take-home message should not be that more sleep is better, but that it is important to allow ourselves to obtain the sleep that our mind and body needs.'
It's not just women, previous research found men with poor sleep patterns have significantly lower levels of testosterone, which results in a lack of sex drive.
Experts say that reduced levels of the hormone can bring a host of other negative consequences for young men, including reduced libido and poor reproduction.
They can fail to build enough strength through muscle mass and bone density, leading to low energy levels, poor concentration and fatigue.
Low testosterone levels are also linked to the metabolic syndrome, a cluster of metabolic risk factors that increase the chances of developing heart disease, stroke, and type 2 diabetes.
Scientists from the University of Chicago found men who get less than five hours sleep a night for a week or longer suffer have far less levels of testosterone than those who get a good night's rest.
Other reasons for low libido include poor diet, being overweight and low iron levels.
