Any idea where is Sweden? That would work against your temperature hypothesis. I personally believe that a lot has to do with people behavior, Northern Europeans tend to be more organized, respect the rules/laws More than the average Mediterranean European and less incline to touching (hugging, kissing etc.) which makes them perceived as ‘cold’...
UV radiation instead of temp?
