Sleep is the Holy Grail to... well, everyone.
The battle to get enough of it is a constant source of stress – and (let's be honest!) bickering.
We all know feeling knackered is a common result of staying up too late, but did you know your body has plenty of other ways of letting you know you need to catch more shut-eye? It doesn't matter whether it's work or the latest Netflix-gorge keeping you up at night, if you are prone to any of the below problems, you need to get to bed earlier.
1. You're always starving
If you can't stop eating (anyone say midnight munchies?!), don't be so quick to put it down to that missed breakfast or the run you went on last night. There is a big chance you are just tired.
According to research by the Society for the Study of Ingestive Behavior, lack of sleep is linked to higher levels of the hormone ghrelin - also interestingly the very same hormone that triggers hunger. So put that bowl of cheerios down and go to bed.
2. You cry at EVERYTHING
It is totally normal to shed a few tears at the likes of One Born Every Minute (Surely that's not just me?!) but if you find yourself weeping over every TV ad, puppy picture or minor discussion with your other half over dishwasher-emptying (happens too), you might need to look at your bedtime.
While we might be quick to blame the aul' PMS for our tears and tantrums, it might be something as simple as lack of sleep sending your emotions into overdrive. According to a 2007 American study, sleep-deprived brains were a whopping 60 percent more reactive to negative and disturbing images and thoughts.
"It's almost as though, without sleep, the brain reverted to more primitive patterns of activity," Matthew Walker, senior author of the study, said in a statement. "In that it was unable to put emotional experiences into context and produce controlled, appropriate responses."
3. You forget things
Find you have trouble remembering where you put the keys again? Or the debit card pin code? The good news is that you are probably not bordering on dementia, you just need to sleep more. According to WebMD, lack of sleep can bring on a whole host of cognitive problems, from difficulty focusing and paying attention to confusion, lower alertness, forgetfulness and even troubles with learning new things.
4. Your sex life is in a slump
Oh, we have all been here, haven't we? But the solution is probably a lot less drastic than you think, and doesn't need to involve either 50 Shades-like role-play or expensive Agent Provocateur. (Unless that's what you're looking for, of course). Just go to bed on time. Sleep enough, and watch the magic happen. Because according to a study published in Everyday Health,
both men and women who don't get their 40 winks experience a decreased sex drive and less interest in getting frisky with their other half in general.
5. You can't shake that cold
Many of us tend to blame the unpredictable Irish weather or even the kids, little germ spreaders that they are, for our never-ending colds and coughs. But if you find yourself unable to kick the constant sniffle, you might need to take a long hard look at your bedtime too. According to a 2009 study, people who sleep fewer than seven hours a night have almost three times the risk of catching a cold than people who slept at least eight hours.
