There are times when your nose is blocked and you can't breathe all too well. And these are the times when you can't really sleep that great and that keeps you annoyed through the whole of next day, which might lead to feeling tired and fogging of the brain. So it's all just co-related.

When your body starts feeling one of the symptoms of an allergy, it releases histamine which makes you feel fatigued. The inflammation that takes place in your sinus during an allergy can cause more infection which tends to make you slow.

If you are about to get some allergy, you might lose your sleep which might lead to brain fog the next day. This is when you're not functioning all too well like the regular days and can't really get yourself to focus well throughout the day. This is called brain fogging as you're unclear of what's exactly happening around you and you aren't too attentive.

You often get mucus when you're feeling the symptoms of common seasonal allergies. And one of them is mucus which your stomach doesn't support that well when you get a post-nasal drip and you end up swallowing it. It makes you lose your appetite as your stomach doesn't really know what to do with the mucus.
