I can usually sleep through a night pretty well, but any time I happen to get woken up by a loud noise or something, I almost immediately get a runny nose, my eyes get itchy, and I start sneezing. I can be in perfect health the night before and the morning after, but something about my sleep getting disturbed makes me feel like I have a cold for about an hour. This has been a normal thing for me since childhood, in every house or apartment I’ve lived in, any season.
