You say to yourself, "Oh no...no...no... I don't want to stay awake for another 2 hours! Body fall to sleep now!"
But the more you try to force yourself to sleep, the more you mind powers up, and you panic and start to become more restless...
If this is the case, maybe this tip will help you get more sleep for the next working day. It's something that I do when I'm on the verge on going to sleep immediately or laying in bed for the next 1 to 2 hours wasting time.
When my body is feeling tired and needs its sleep, but more mind wants to stay up, what I do is pretend that instead of having 8 more hours of sleep, I only have 10 more minutes of sleep before I need to get back to working again for hours (no break).
No break? My body says, "No! I must have my sleep now!" Then magically, I start drifting back to tiredness again. That's how I kind of use reverse psychology to trick myself to sleep sometimes.
I'm sure you've also had those days where the alarm clock rings 10 minutes before it should and you immediately press the snooze button or your parent or spouse tells you to get up and you tell them 10 more minutes!
What you are really doing is savoring these 10 minutes of precious sleep before you go into a full day's of work again, so you shut your eyelids and roll back in bed.
That's what we're trying to do here - to trick the mind to using scarcity, or a scarce amount of time left before getting back to work. If you really believe in it right before you're body starts to become active again, you'll start to appreciate just lying there and letting your body rest.
So I hope this random tip helps. Try it out when you come across times where your body is tired and wants its usual 6 to 8 hours of sleep, but your mind wants to suck out an extra 1 to 2 hours of sleep from you by staying restless.
