The clocks going back hold the tantalising promise of an extra hour in bed. But the modern attitude towards that champion of indolence, the sloth, shows that sloth is still very much a deadly sin.

Imagine being unable to talk or move when faced with an evil intruder.
Sleep paralysis is an enigmatic, terrifying condition in which the mind is awake but the body is asleep. But how much do we actually know about it?
We now have the technology to do track our sleep through the night, but that may be doing more harm than good.
Tracking sleep is now routine in monitoring overall well-being. But are the devices used to do this actually useful, or have we simply found a more sophisticated way to clock watch?
Popular characters such as Sleeping Beauty illustrate our enduring interest in tales of people who sleep continuously or cannot stay awake.
Perhaps because we all need sleep, we have an enduring interest in sleep disorders such as narcolepsy, which causes a constant irrepressible need for sleep.
The activities we do during the day – from having a fight with a partner to using our iPhones at night – also affect our hormone levels and, in turn, our quality of sleep.
Sleep allows many of our hormones to replenish so we have the optimal energy, immunity, appetite and coping ability to face the day’s highs and lows.
