Tired all the time? Need a coffee or SEVEN to get through the day? Then perhaps you're not getting enough sleep.
Even if you're racking up nine hours of kip per night you might just need a little more. But how do you know whether you're getting enough shut eye? If only there was some sort of 30 second test you could take...
Fabulous news - there is! Richard Wiseman, a psychologist, pro-sleeper, and author of Night School, has created a quick and easy way to find out. Watch the video below to discover whether you need to spend more time in bed. You might just surprise yourself.
1) Listen to relaxing music.
2) Avoid using technology. Stay away from computers, smartphones or tablets in the two hours before you head to bed. The blue light stimulates your brain and prevents you feel sleepy.
3) Make a list. Jot down all the things you have to do the next day or that are playing on your mind.
4) Tire your brain. If you are struggling to sleep, make your brain tied by thinking of an animal for each letter of the alphabet ('A' is for 'Ant', 'B' is for 'Bear').
5) Move your bed. We have evolved to feel safe when we can spot danger early and have time to run away, and so will feel most relaxed when your bed faces the door and is furthest from it.
6) Eat a banana. They're rich in carbohydrates, and these help relax your body and brain.
7) Reverse psychology. Actively trying to stay awake actually makes you feel tired, so try keeping your eyes open and focus on not falling asleep.
8) Wear socks. If you have bad circulation, your feet will get cold and cause sleeplessness.
9) Avoid booze. (Sorry).
10) Do a jigsaw. If you lie awake for more than 20 minutes, get up and do something like working on a jigsaw.
