This is a serious question. When I sleep my outer ears become so cold that it wakes me up. I have no idea what is happening.
I'm afraid this is something you will have to talk to a doctor about as there cannot be found any condition, disease or disorder that causes cold outer ears. Talk to a doctor for tests, evaluation and proper diagnosis.
you should try sticking a cotton ball in your ear so it will block out any coldness
your outer ears are becoming cold
Off the air conditioner if it dosen work, u have a serious situation here
Try covering your ears with the sheet or blanket when you sleep. :)
Wear a sleeping hat like they did in the old days.
