I could not find relevent research
I lived 3/4 of my life in relatively warm weather
the time I lived in cold areas or during vacationing in less than 10 degrees centigrade my digestion track which is at the heart of my health issues improves significantly. my IBS disappears like it never existed.
I feel more comfortable in cold weather.
are there genes for such things?
I also eat twice as much more and do not add weight in cold weather.
