I do not know so much of foreigners in Finland, but when there are problems, it is often that the problematic aggressive persons have too thin clothes or too little room for warm air inside clothes, so machine knitted thick fabric of a very loose size would be much better. If you feel cold, winter time indoors clothes may be needed already in the sjmmer time. Or then they have not eaten the normal foods of the season of where they are in Finland, for example now in November that could be laatikko ( foods called "box" ) that is warm and with it some butter too, plus raw carrot or the like in tiny pieces, and maybe a glass of milk.
