So after summer i moved back to uni, into a new accommodation. My room is on the ground floor and the floor is always ICE cold (because it’s winter) and recently i noticed one of the windows in my flat is not fitted right or something so it never actually closes, obviously then meaning my whole room is just ice cold and there’s always a draft. could that be a reason i’m getting sick so often? literally i have flu symptoms non stop for months and it gets a little better for two days and comes back worse and repeat. Not sure what it could be
