We already know that insomnia is more prevalent in women than men; now a new study tells us that women who drink are more likely to suffer with sleeping problems than male drinkers.
The study found that women who drank alcohol in quantities high enough to get drunk got around 20 minutes less sleep than those who drank caffeine-free cola.
Now, that may not sound like a lot of sleep loss, but it's the equivalent of 4% of your total sleep time if you're aiming for eight hours of sleep each night. It's especially relevant as a 2010 study found that women need 20 minutes more sleep than men.
So why are women more susceptible to sleep disruption after drinking alcohol? Apparently it's down to the fact that women metabolize alcohol differently - because women tend to have more body fat and less body water than men, they tend to end up with a higher breath-alcohol level even after drinking the same quanities as men.
On the plus side, female bodies process alcohol quicker than male bodies - so at least the hangover might not be quite so bad the following day. Enough to make up for that loss of 20 minutes?
