ELI5: Why are symptoms more potent in the morning and evening when you are sick?

I am sitting here right now with some kind of cold (swallowing hurts, bit coughing) and I always wondered why my symptoms always seem to be less potent over the day but very potent in the morning and evening?

In the morning it's usually because you've been dehydrated due to sleep or if symptoms just arose, you aren't used to it. In the evening, because of being tired and talking all day, you get worn out. Just think of going to a sporting event all night yelling then getting home and having a sore throat. Wear and tear of everyday things just exaggerates your ailment.
