Research has long found those who sleep between six and eight hours a day are less likely to develop a host of diseases - and even live longer.
But what about bedtime?
Surprisingly, recent research suggests that maintaining a consistent sleep routine could be more beneficial than more time in a slumber.
Dr Chris Winter, neurologist, sleep expert, and host of the Sleep Unplugged Podcast, told DailyMail.com that he recommends going to bed and waking up at the same time every morning.
'In general, sleep schedules are important because our bodies work best when they're able to anticipate what's coming rather than simply react to it,' he said.
