When you wake up in the middle of the night, it may be for one of several reasons of which you are not aware:
Perhaps you unconsciously became hungry during the night.
You may have too much covering on and not realize it. Being too warm may make you just uncomfortable enough to wake you and keep you awake, yet not uncomfortable enough for you to know why you awoke.
Maybe you are not physically tired—maybe you -went to bed too early. Don't think it's necessary for you to have eight hours (or any other particular amount) of sleep every single night.
