We all recognise the value of a good night’s sleep and over the years some simple rules-of-thumb have been established to maximise our sleeping potential; yet much of what is known about sleep isn’t accurate, according to a leading lifestyle expert. In an interview with Today this week (October 3rd), medical contributor at Prevention magazine Dr Holly Phillips exposes some major ‘sleep myths’. Some common misconceptions that could be making us more tired include: many people are “short sleepers”, napping only makes you more tired, sleep catch-ups at the weekend do the job, and it doesn’t matter what time you go to sleep. She went on to say that most people require at least six hours of sleep each night and, contrary to popular belief, a brief snooze of less than 20 minutes can work wonders. Furthermore, sleep-deprived weekdays cannot be made up with a mammoth sleep at the weekend, while there is also an optimal time to go to bed and wake up in the morning – though, the reasons for this have not yet been established.
