We all know that late night Netflix binges and nights out drinking our body weight in tequila shots doesn't make for great skin.
Almost half of Brits get just six hours' sleep a day which is 25 per cent less than the recommended 7-8 hours.
But, if you've ever found yourself going to bed early and still waking up before your alarm clock next to a sound-asleep partner and having to apply thick levels of concealer to your lower eyelids, science has found an explanation.
A new study has found the reason women why women sleep worse than men is because their circadian — the biological clock that controls when we're asleep and awake — is two hours ahead of men’s
Published in the Proceedings of the National Academy of Sciences, the research involved Canadian scientists following a group of 25 men and women for 72 hours to observe their body clocks and analyse their natural sleep patterns.
For three days, the volunteers were placed in a laboratory and kept awake for an hour before being allowed to nap for an hour, if they so wished.
During this time, the scientists monitored their alertness levels and their circadian rhythm which encompasses their core body temperature and melatonin levels (the hormone that makes you want to go to sleep).
In the end, the research found insomnia to differ between the sexes, with women 50 per cent more likely to have troubles sleeping than men and boast a circadian rhythm between 1.7 and 2.3 hours in advance of men.
Great. Yet, another biological function we drew the short straw on.
Jokes aside, a lack of sleep for women is detrimental to the well-being of their skin and can result serious tissue problems including in inflammatory conditions, fluid accumulation (hello, puffy eyes), dark circles and premature aging.
