Seems to me that this can only reduce blood flow to the fingers. Thus making them colder.
Using myself as an experiment. Today I didn't drink coffee before my ride, fingers were not cold. I drank coffee when I got to work and had to pee a lot. Thus coffee is a vasoconstrictor and a diuretic. I know more studies are needed but it worked for me.
Whether coffee is a diuretic or not does not affect the morning commute. I don't think I get hypothermic nor dehydrated on a 10 mile commute. Charlie
Coffee has no effect on my feeling cold or not, therefore, i know what you are saying is not true for me.
It just sounds like you have bad circulation.
