Been thinking about this since… 6 days ago!, haha

and! This:

"Cis-urocanic acid, a sunlight-induced immunosuppressive factor, activates immune suppression via the 5-HT2A receptor"

https://www.pnas.org/doi/10.1073/pnas.0603119103

(We are all coated in urocanic acid. Right now. We secrete it. ahhaha. what!! And. It isomerizes in UV light and plops into the 5-HT2A receptor and downregulates inflammation.)
