ITV This Morning doctor Michael Mosley says one of the classic mistakes made by anyone who can't sleep is to try to spend MORE time in bed.
The popular TV doctor said the most effective way to cure insomnia is to "reboot your brain".
Mr Mosley said: "It might sound like a good idea, but lying in bed wide awake, worrying about how tired you’re going to feel in the morning, can be very stressful and certainly not conducive to a good night’s sleep.
