Adult Thermal All Weather Suit Going To The Snow...and Having Asthma?

Going to the snow...and having asthma? - adult thermal all weather suit

I will be snowing and the surrounding areas in 2 months. I currently live in Brisbane, where we have relatively mild winters (eg, a sweater and jeans is enough to keep the heat - no heat or what was required) in the last year I is a diagnosis of asthma in adults was achieved with an attack twice per day at present (250/50 dose) that I wondered if the cold could affect all asthma and if I my doctor before you leave? I do not know much about asthma is no longer so sure that things like that. Thanks
