Getting cold hands and shivering after dosing

As the title says, I’m curious why I get cold hands and full body shivers after micro dosing. It can last 2-3 hours, generally starts 1 hour after dosing. This happens consistently whether I do 5-10 micrograms of LSD or 150-250 mg of mushrooms.

Typically I dose on an empty stomach in the morning with some black tea.

Thanks!
