I have this issue often. I know if I scratch, it will wake me up and take longer to sleep because of my body movement. If I don't scratch, my mind only focuses on the itch. Sometimes I'll wait 5 minutes for the scratch to go away and then I just cave and start scratching any minor itch I have on my body. Has anyone just not moved and let the itch subside or does everyone scratch?
It's the easiest when in bed to scratch an itch! Imagine you're going downhill on a bike, and your back is itchy all the sudden, or you're swimming in the olympics and you're now itchy... people take this for granted!
