Getting a "beauty sleep" is apparently a thing and there's a specific number of hours you should stay in bed for to look your best the following day.
If you want to avoid the rough look a bad night's sleep can give you - bloodshot eyes, bad skin - read on.
A study has revealed the optimum time to go to bed. Bed manufacturer Sealy UK, which conducted the study, found people who get an average of 9 hours and ten minutes of sleep a night reported the most improvements to their physical appearance.
These people reported clearer skin and brighter eyes, all because of a good night's sleep.
According to RSVPLive, the study also found the best time to go to bed is at 9:45pm, with a wake-up time of 6:55am.
