I know this might be a weird question, but I'm really interested in the ways that the senses can really alter your physical and emotional state, other than sight and hearing. 

I bought some Icy Hot patches at the grocery store today, and I HATE going there. For some reason grocery stores seem to flare my anxiety horribly and I don't know why. Anyways, I was still feeling super panicky even though I was home, and I went to put the Icy Hot on my back since I have a pinched nerve. I hasn't used these in a while and I forgot about the rather strong 5% menthol scent, but holy *shit* I felt so calm after I smelled it. 

I literally just sniffed the paper you peel off of it for a few minutes after I put the patch on my back. I felt totally fine after those few minutes. 

My fiancée has a Yankee candle in her room that she doesn't actually light, but she'll just sniff it if she's feeling anxious (it's the Macintosh apple one, it smells so good!). 

What about you guys? Any scents than can bring you down from 100 - 0 real fast?
