Why do we get sick? And is a cold really just our body being overdramatic? In this episode of Explain It Like I’m 5, Alex dives into the sneezes, sniffles, and science of sickness.

From bacteria, viruses, fungi, and parasites to the immune system’s dramatic defense strategies (fever, mucus, sneezing at 100 mph), we’ll explore why being sick often feels worse than the germ itself. Learn why some people get sicker than others, why colds are so stubborn, and how vaccines train your body like a superhero squad.

Plus, quirky facts (yes, chicken soup actually helps) and the evolutionary reason sickness exists at all.
