According to an article published today by The Independant new paper,
"There are a few things you can do if you're lying in bed and struggling to sleep. What you shouldn't do is play on whatever is making you feel anxious. Tiring your brain is a good idea. So, for example, think of an animal for every letter in the alphabet. Another good way of distracting the mind is thinking of very positive scenarios. When we interviewed super sleepers (people who can sleep at the drop of a hat), most of them were doing that. They build a fantasy world in their head and drift off with very positive imagery. It's also quite fun. Interestingly, if you ask people to stay awake, it helps them get to sleep. Being told they must keep their eyes open (blinking is allowed) makes them nod off more quickly. Insomniacs are often told to try this."
