I noticed whenever it's starts getting cod outside, for example the winter time and I go to sleep, the next morning when I wake up, my throat feels dry/sour, my ears feels like it's been blocked somehow, and my nose are dry and it kind of hurts. Anyone knows the reason why this is occurring?, or any solution to it?. It's and of disturbing knowing you're about to go to sleep and the next morning you're going to wake up all weird. I don't think am sick, am fine, my temperature is OK and am pretty active during the day, but whenever I wake up, my nose, throat and ears feel like that.
